|“||You’re really tiny and I love you||”|
— Spencer to Aria

In "To Kill a Mocking Girl," some of Spencer's supplies spills out of her locker. Aria helps her put the supplies back in, and Spencer asks Aria if there was a chance Aria's family could adopt her. Spencer tells Aria she's basically drowning AP Russian History, because she hasn't written her essay which is due Monday.
In "Reality Bites Me," Hanna says that Byron should in least be with someone who, "deep conditions her hair occasionally." Aria became offended. After seeing Aria offended, Spencer took some food from her fridge and said, "Here, put something in your mouth other than your foot", basically telling Hanna to say sorry to Aria.
In "There's No Place Like Homecoming," Spencer, Hanna, and Emily come over to Aria's, thinking she's feeling sullen because of her parents breakup, when she's really just sad about Ezra. While Aria is sleeping, Spencer wakes her up and touches her, and then starts convincing her to go to Homecoming with the other girls.
In "The Perfect Storm," Aria and Spencer practice for the SATs, which will be happening the day after. Hanna is also there, but as she phrases it, "They worked, and I annoyed them." Aria flipped through cards while Spencer said the definitions (without looking at them). Also, when Hanna says, "You don't need to know any more words than this. You're already scary to anyone under 50," and when Spencer says, "Am I scary?" Aria smiles and replies, "A little."
Later, when Spencer meets Alex at school the next morning, Spencer and Alex are kissing, and Aria tugs Spencer's arm so they stop kissing.
In "Keep Your Friends Close," Spencer and Aria arrive to Mona's birthday party together. As Mona welcomes them to her birthday party, "Camp Mona", they exchange glances.

In "Moments Later," when Aria reveals to her friends about her relationship with Ezra, Spencer is shocked. Spencer says that she's surprised to know that Aria's affair had been going on for a while. Aria says she, "didn't just get into his car last night. Who do you think I am?"
Later, Spencer and Aria walk in the woods and talk about Aria's affair with Ezra. Spencer comments on Ezra and Aria's relationship by saying, "Part of me thinks this is self-destructive behavior, but most of me just thinks this is really hot." They're looking for the tree with the "Alison + Ian" carving, but it turns out that the whole tree has been chopped off.
After that, Aria and Spencer arrive at Spencer's home to talk. Ian invites them outside to make a toast of champagne. Spencer asks Ian why they are celebrating and why he had canceled Varsity field hockey practice, and he admits that Melissa and him eloped. Aria and Spencer are both shocked, however Aria is the only one to congratulate them.

In "Touched by an 'A'-ngel," Spencer is worried about Aria getting close to Jason because she believes he's dangerous, so Spencer gets Ezra to try to talk to her and exposes the fact that she knows about their relationship to him. She expects Aria to be mad, so later she tells her "You're really tiny, and I love you!" as her excuse for being so nervous.
In "UnmAsked," Spencer wants to get a closer look at the guest book in the Lost Woods Resort, and Aria is the only one who volunteers to go with her to look at it, causing Spencer to look at her admiringly and say "You're little, but you're big". Spencer also calls her and Aria, "Team Sparia" in this episode.
In "Stolen Kisses," Dianne, Ezra's mother, invites Aria to go to a museum event. Dianne is very formal. According to Aria, she "wears diamond and Chanel on a Sunday morning". Aria asks Spencer to help her, saying, "I want something classy, but not frumpy." Spencer, offended, folds her arms. Spencer and Aria see Veronica's briefcase in Spencer's kitchen, so Spencer decides to open it and look in Garrett's file. Once they look through the file, Spencer and Aria find the name Bart Comstock in the prosecution witness list. Aria asks Spencer if she wants to come with her to find that man. Spencer says she wish she could, but she said she'd meet Caleb after school to crack open Maya's website. Aria says she will go herself. After cracking open Maya's website, Spencer and Aria talk over the phone. Spencer asks if she got information from Bart, and Aria tells her that Bart told her that he saw Maya get into a police car the night she died.
In "The Kahn Game," at The Brew, Aria shows Spencer a photo of Maya's arm with the same black eye tattoo that Holden had from the past episode. Spencer expresses no concern for the photo as she starts to stress about missing the early admissions deadline to the University of Pennsylvania. CeCe comes in and gives Aria back her phone which she left on the counter. She hears about Spencer's issue. CeCe says that she knows about a Friday night party where a man that takes UPenn admissions will attend. Spencer desperately pleads with "puppy dog eyes" for CeCe to let her and Aria tag along to the party so Spencer can give her application to UPenn. CeCe accepts.
Later, Aria and Spencer get ready for the party. They are talking on the bed. Aria revels to Spencer about how Ezra told Aria to leave his apartment earlier. Spencer proposes clothes for herself to wear, asking for Aria's opinion. Spencer first shows two suits, which Aria downright refuses. Spencer says, "Those are my most collegiate-looking blazers." Spencer then takes a dress from her mother's closet, to which Aria asks, "Is that your mother's?" At first, Spencer says no, but then she admits that it is her mother's. Aria jumps off the bed and looks into Spencer's closet. She picked something out for Spencer to wear.
In "Turn of the Shoe," Aria comes over to Spencer's house and sees Toby and Spencer (Toby looks sad). She asks Spencer if they're okay, and Spencer says she's fine. They talk about Aria's martial arts lesson and picking up Mona from the Police station.

Aria says she will meet her later.
Later, Spencer and Aria spy on Melissa outside of the barn. Spencer is taking a video with her phone, while both the girls move to wherever Melissa moves. When Melissa goes to Hector Lime's place, Spencer and Aria watch her and spy on her all the way there. Then, Spencer instructs Aria to spy on Hector while Spencer confronts Melissa. After getting answers from both Melissa and Hector, Spencer and Aria talk in Spencer's kitchen. Aria questions her about Spencer's answers and if she believes Melissa. She also asks her if she thinks Melissa killed Detective Wilden. Spencer doesn't reply.

In Under The Gun, Aria and Spencer discuss Spencer and Emily's fight at The Brew. Aria tells Spencer that she and Emily need to apologize to each other to get all heads in on -A. Spencer replies with, "Aye aye, Captain."
Later, at The Brew, Aria talks to Spencer. Aria gets worried and says, "First Hanna, and now Emily," [about going to the police station]. Then, Spencer said, "Don't say it like that." Aria said, "Like what?" Spencer replied, "Like one of us is next." Then, when they start talking about Shana, Shana immediately comes in and starts playing her violin.
In Into the Deep, at school, Spencer and Aria discuss Mona between classes. They know Hanna wants to believe she confessed for the right reasons, but Spencer knows Mona can easily twist it around and make it seem like they forced her to do it. Mona could also try to pin Wilden's murder on the girls since she has the photo of them tampering with his car. Aria shows Spencer Emily's birthday gift - a framed photo of Paige and Emily. Then the girls come across Jenna and Shana having a hushed conversation about Alison. Jenna says "they know I'm hiding something," that she should have told the police about Alison, and also that it's "too dangerous not to say anything at this point." Shana asks to give her a little more time to figure out where "she" is. Jenna expresses her anxiety about losing her sight again, and Shana says that she won't leave her side until she takes her back to Philadelphia the next morning. At Paige's aunt's lake house, Aria and Spencer are helping Paige set up for the party. They discuss what they overheard Jenna talking about and the possibility that Jenna knows Alison is alive. They decide they have to get Jenna alone to find out what she knows. Spencer says that Toby told her Jenna's eye-surgery had a low success rate and unfortunately Jenna is losing her sight again. At the party, Spencer notices Aria stewing in the corner and finds out her attitude stems from the fact Jake brought a leggy-blonde to the party. Aria is clearly jealous of the pair. Spencer says the girl is trying way too hard and that Aria should go talk to Jake, Aria chooses not to break up the "flirt fest" and though she clearly feels otherwise, insists to Spencer that she is not that into Jake. Spencer and Aria corner Jenna and Shana and Spencer asks about Jenna's eyesight. She says she sees everything she needs to see. In an effort to get Jenna alone, they say they are taking a big group photo outside.
In Love ShAck, Baby, at school, Aria leaves a pen on Ezra’s desk and Spencer asks her what she was doing in Ezra's classroom. When Aria makes up excuses, Spencer openly asks her if she is still in love with him. In Ezra's cabin, while in the la undry room to get blankets, Aria and Spencer are trapped there. Aria looks through the keyhole and sees a hooded figure walking around. They open a window and scream outside for help, and Hanna and Emily both hear them. They break a window to get into the cabin since the front door was locked. They open the door and let Spencer and Aria out, but discover that Ali’s journal is gone.
In Bite Your Tongue, after Spencer realizes that Ezra is Board Shorts, she is conflicted on whether to tell Aria as it would strain their frienship. After 'A' plants a message in Hanna's teeth, Aria, disgusted by this asks "Who is this monster?" and Spencer looks at her guiltily as she believes Ezra is 'A'.
In Spencer’s bedroom, Spencer is flipping through Bethany’s sketch book that Aria took from Rhonda, and she tells Aria that she knows it was her idea, but “you cannot go back to Radley”, to which Aria tells her she has to, “maybe Rhonda knows who visited Bethany and who Bethany’s friends were”. Aria goes on to say the more she finds out, the closer they are to exposing ‘A’. Finding a ripped page, Spencer asks to see the drawing that Eddie left for Ezra, and they work out that the Mrs DiLaurentis drawing was the last thing she drew, and that she must have left Radley after drawing the picture. Spencer wonders “did she leave hours later? Weeks? Days?” and Aria questions how she ended up at the DiLaurentis house. Going through the earlier drawings, Spencer comments that they’re “so normal”, and it’s just what you would draw in an art class. As they continue to go through the drawings, Aria asks how Spencer went today, “with Ezra”, and as Spencer tells her it was fine, Aria asks “you didn’t say anything, did you? About…”, but Spencer wonders why she would slip her into a conversation, “you guys have done enough slipping on your own”. Aria and Spencer watch as Bethany’s drawings get darker in content, and getting to one drawing, Aria comments that it looks like a Chagall, “flying like that”, but Spencer mentions that it’s not flying, and as she turns the page vertically, says “she’s falling”. As Spencer tells Aria to look at the vines and the bars on the windows, Aria concludes, “someone falling at Radley?” and Spencer questions, “Toby’s mother?”, before Aria wonders if Bethany saw that, only for Spencer to say she either saw it or heard about it. Aria wonders if Spencer thinks Bethany was the fragile patient that was on the roof with Toby’s mother that night, and Spencer questions who else knew Bethany at Radley. Flipping over the page, the girls find a picture of Jessica DiLaurentis with demon horns, and Spencer says that Mrs DiLaurentis was on the board, and she was part of the cover up, to which Aria concludes, “so Bethany left Radley, and went looking for Mrs DiLaurentis”, and Spencer finishes her thought process, “and found someone waiting for her with a shovel”. Aria thinks maybe that person was ‘A’, and Spencer tells her that she has to show the pictures to Toby, only for Aria to tell her to take a picture, she’s got to get the book back under the mattress before Big Rhonda finds out it’s missing.
In her living room, Aria is on her phone to Spencer and tells her that she’s walking out her door “right now”, and no she hasn’t talked to Hanna.
In the Hastings’ kitchen, Aria is watching Spencer’s security video of Alison with Emily, and asks Spencer where Alison is going and if she saw her come back, but Spencer tells her Alison hasn’t come back.
Spencer: You're really tiny, and I love you.
Aria: I love you too.
Aria [after taking a sip of coffee]: Ugh. Taste this. It's disgusting.
Spencer: No, you just spit in it.
Aria: You could've announced yourself.
Spencer: Hi I'm Spencer. I'm climbing into the crawl space.
Aria [referring to the red coat]: Can I touch it?.
Spencer: Yeah, it's a raincoat Aria. It's not a mummy.
Spencer: Am I scary?
Aria: A little.
Spencer (to Aria): You're little, but you're big.
Spencer: I'll do it. I just need you to stand guard. Come on! We're Team Sparia!
Spencer: Something’s now going on and, I really have to tell someone about it. I really have to tell you about it. But if I’m right, then that would just break your heart. And if I’m wrong, then you’re going to hate me forever. And that would just break my heart.
Aria: I've been seeing Ezra again. Really seeing him, if you know what I mean.
Spencer: Yeah, I think so.
Aria: But you said it yourself. I liked Jake, but I love Ezra. I do love Ezra.
Spencer: Who are you trying to convince?
