With Ali alive and lurking somewhere around town, the Liars have to go to work to find out what’s holding her back in Pretty Little Liars Season 4 Episode 15, “Love ShAck Baby.” From the synopsis for the episode, we’ve learned that Hanna finally came clean in the winter premiere about swiping Ali’s diary from "A"’s lair in the summer finale. So, what’s next?

Like many problem-solving seshes on PLL, the girls have to turn to the past to find out what to do next. In the episode, “the girls hope it can shed light on their many questions.” But what questions, exactly, are on their minds? It’s hard to imagine where they would start.

“With the diary full of stories that have been coded to cover the truth, each girl must take a turn to figure out which stories are about them.” Uh oh, Ali can be pretty cruel in her nicknames (“Hefty Hanna,” anyone?), so it’s hard to imagine the Liars will be quick to give themselves away with details they might have been hiding from each other. In fact, fans are told as much, since each story is “more personal than the last,” and they don’t “really want to admit” which story is about them.

Oh, and just to make sure we don’t forget about all the weird stuff happening at the DiLaurentis house, Spencer has spotted her dad interacting with Mrs. D, and is “suspicious.” Fair, but when is she not?
