|This article is about the location. You may be looking for The Incident at Thornhill Lodge, the event that occurred at the lodge.|
The Lodge emerges for the first time when Spencer invites Emily, Hanna and Aria to a party, which turns out to be a set-up and a meeting place with "A." Later in the episode, Hanna, Aria, and Emily sneak up on Mona. Shana locks the building from the outside and Wilden sets the lodge on fire, trapping the girls and Mona inside. We see someone in a red coat land her plane on the landing strip. She pulls the liars out of the burning lodge. Hanna looks up and it is Alison DiLaurentis. As they are coming to, Mona runs over and asks if anyone else saw her, exclaiming that it was Alison that saved them from the fire. Hanna and Spencer both confirm that they saw her too.
Toby watches a fireman pull a red coat out of the debris the morning after the fire at the lodge. Spencer and Toby later go back to look for clues. While they where searching, Spencer sees a figure who quickly gets away before they could catch him/her.
Melissa reveals to Spencer that she sent Jenna and Shana over to the lodge in order to find out who the girls were going to meet because they were suspicious that it may have been Alison, and that Wilden showed up and he started the fire.
- The lodge is named after the character Roger O. Thornhill, played by Cary Grant, in the 1959 Alfred Hitchcock film North by Northwest. This goes along with the overall North by Northwest theme of the episode, "A DAngerous GAme."
- Melissa says Wilden was the person who set the lodge on fire.
- It is revealed that Shana was the one who locked the girls in the lodge.
