In this new sneak peek of Pretty Little Liars Season 3, Episode 23: “I’m Your Puppet” (airing March 12), the Liars try to convince Spencer (Troian Bellisario) that the body she saw wasn't Toby's (Keegan Allen).

In the sneak peek, Hanna (Ashley Benson) tells Spencer that the "park rangers found a body" — and it wasn't Toby. It was some random camper who's been missing for a while. According to Aria (Lucy Hale), he was "nowhere near where you thought you saw — "

Spencer doesn't even let Aria finish that thought, cutting in with "I know what I saw. It was Toby." And, to be fair to Spence, the rangers finding a potentially unrelated body in a different part of the woods isn't exactly compelling evidence that she's wrong about what she saw.

Suffice to say, the Liars' "good news" doesn't convince Spencer that Toby's alive, and it also doesn't convince her to check out of Radley. "I have to stay here. I need more time," she cryptically explains, before adding that she feels safe inside the mental institution. "Those bars don't just keep you from getting out — they keep other people from getting in."

Check out this sneak peek below. Those of you who don't mind spoilers can learn more from the official synopsis of the episode.
