Are you sitting down, Pretty Little Liars fans? ABC Family has released a new clip of Spencer (Troian Bellisario) and Melissa's (Torrey DeVitto) conversation on Season 2, Episode 22: “Father Knows Best,” and it's less of a sneak peek, and more of a sneak OMG WHAT.

In this super revealing video, Melissa tells Spence that she's been talking to Garrett (Yani Gellman) for emotional support after Ian's (Ryan Merriman) death, but now she thinks she's told him too much, including her suspicion that Ian isn't the one who killed Alison (Sasha Pieterse)...and that, on the other hand, her dad might have been involved.

That's right: Spencer isn't the only one who's noticed that Papa Hastings is hella sketchy about the murder, and now Garrett knows, too.

Watch the whole clip below.
