In Entertainment Weekly’s clip (viewable here), Garrett visits Spencer at her house. He tells her that it’s time for him to move on, away from Rosewood, so he can find closure.
“Why don’t you start the healing process by telling me what you know?” says Spencer. But that’s when Toby (Keegan Allen) walks in. “You’re leaving,” he tells Garrett, looking pretty scary considering we know he’s on the “A” team.
After Garrett’s gone, Spencer tells Toby, “He said he would tell me what happened the night Ali was killed, and who stole her body.” Clearly, Toby isn’t going to let that happen, which is why we think Garrett is going to be the character who dies on the Halloween ghost train. (Read four reasons why we think Garrett won’t make it to the winter season here.)
One of the reasons why this is such an important sneak peek is because of what PLL showrunner Marlene King recently revealed in an interview: “This character dies because he has a huge secret and is about to reveal that secret to a Pretty Little Liar. That’s the reason why this character is killed.”
Does that pretty much put the nail in Garrett’s coffin?
In a bittersweet moment from the clip, Spencer gives Toby a lovey-dovey hug, but when we see Toby’s face, all he’s thinking about is how he’s going to shut Garrett up — for good.
