More info from the private detective. At :03 we see that Spencer meets up with her private detective again, which probably means he finds something on Toby (Keegan Allen).
The "A" key plays a roll. At :07 we see one person holding an "A" key, and another an envelope. We think it's the private detective returning the key to Spencer.
Wesley gets a call — and Hangs Out With Aria. Wesley (Gregg Sulkin) is back this week, as we see at :08. At :20 and :22 we see Aria (Lucy Hale) is with him.
25 opportunities to set Emily up. We hearEmily (Shay Mitchell) say, "'A' has 20 opportunities to set me up," which is explained in this sneak peek.
Emily freaks. We already knew Emily is going to undergo hypnotherapy this week. It sounds like she doesn't love it, since we hear her say "I'd like to wake up now," and at :14 she looks very freaked out.
"Stop!" We've already seen Alison (Sasha Pieterse) screaming "What do you you think you're doing?" in a flashback in the American preview, but here, it sounds like she also says "stop."
Hope? We see Spencer (Troian Bellisario) telling someone, "I open the door. If it's full of the things I think it is, then there's hope." However, at :22 we see Spencer gasping after entering a room. Is that the room she's talking about? If so, it sounds like things don't work out the way she wanted.
A fight. At :24 we see two people in what appears to be a fight. We think one of them is Wesley, but we're not positive.
