Aria's dealing with Ezra's absence as well as she might -- mostly by putting on her most ridiculously infantile outfits and lounging around -- when little brother Wesley appears, clearly on the run from prep school. After some sudden violence, we learn the truth: Wesley attempted to sleep with one of his teachers, and got thrown out. The only thing more unbelievable than that? Aria's response, to wit: "That's the stupidest thing I've ever heard." Girl, we know. We have been saying that for three years.

Hanna forces a very shirty Caleb into helping go through old crap from his mean aunt's house -- the one that tossed him into the system -- with help from her brother, the foxy Jamie Doyle. But what Hanna eventually figures out, and Caleb cannot accept, is that Jamie Doyle might well be Caleb's father. For a person with no parents, I gotta say Caleb sure has a shitload of parents.

Now that Alison's body has been found on the Halloween Train, it's time to put her to rest for like the tenth time. This time she's going in a mausoleum, presumably due to some kind of diminishing returns situation where there's probably not a lot of left of her after all this constant molestation of her remains. Jason seems a little miffed that Spencer isn't more interested in her latest memorial, but the other ladies are on board.

Aria and Emily are kind of paranoid about being in receipt of their mementoes (Ouija planchette, those ubiquitous earrings), since it makes them look like graverobbers, but it's actually Emily's that take center stage this week: Apparently she popped 25 postcards in the casket, remembering one beautiful flirty day with Alison when postcards were a thing. Of course, now that means that A has 25 chances to blackmail the ladies, and the first one starts with a message in French reminding Emily that she killed a dude.

Which is all it takes to send her down the rabbit hole. She heads off to Therapy Anne to deal with her murder situation, and while it's eventually good old Pam that fixes the problem, Anne loads Em up with a host of new issues (before receiving a suspicious visit and orchid from Miss Vanderwaal): Namely, some random false memories of that night Roofie Emily did one thousand things. One of those things, turns out, involved helping A and Red Jacket Girl dig up Alison's grave. She muddles the memories, though, and spends most of the episode thinking she was the one that killed Ali, but once they hit the mausoleum she works it all out. And not only that, but the nature of Red Jacket's role as A+ on the A-Team.

Spencer, on the other hand, continues her downward spiral into crazytown, letting little things like Mona's continuing menace and the iffiness of her private investigator send her reeling. When the guy eventually tracks down Lair 3.0, she's somehow got it in her head that Toby might still love her and/or be sticking around, but 3.0 turns up as dry and depressing as the rest of her life, so she somehow goes even more crazy over the course of about five different musical montages. In the end she goes on a rampage through the mausoleum, making all the girls cry and telling Jason about Ali's pregnancy from sleeping with Wilden in Jersey, before finally carving Toby's name on his mother's own gravestone in some kind of firing-blindly act of desperation.

In the end, the Liars focus on the fact that they're losing Spencer, but may have figured out the basics of a third A-Team member -- and that possibly she is Alison DiLaurentis, who not only stalked herself backwards in time but is now also digging up her own grave from the future.

Next week: Spencer flies through the air like the Vampire Queen, burying her teeth in Mona's neck. Aria and Wesley continue to moon about, while Hanna devises some kind of ill-advised scheme to reunite Caleb with yet more of his many parents, which will probably result in their near-deaths also. Emily's therapy reveals more flashbacks to lesbian yearning and/or gravedigging, and she helps Jason figure out the shitstorm Spencer just stirred up.
