Finding out Ali was alive was just the beginning of the drama for the Liars, as they’re about to find out in the Season 4 winter premiere, “Who’s in the Box?”

With her boyfriend off in Ravenswood, Hanna puts on her detective hat and “comes up with the idea that if they find out who is really buried in Ali’s grave it may lead to much needed answers.” We wonder if something she finds in the blue journal she took from “A’s” lair will lead her to anyone in particular.

Meanwhile, “as the girls search, Emily has trouble dealing with how she feels about Alison being alive.” This is perhaps the most intriguing sub-plot of the Ali reveal. Emily has matured so much since the days she was under Ali’s thumb, and since we know Ali was Em’s first love, she must be feeling confused about the shocking turn of events. Does Ali have any remorse for how she treated Emily? Will Ali and Emily share a moment in the premiere? And how will Paige feel abouit it all? We’ll have to wait and see!

Lastly, “Caleb returns to Rosewood,” which isn’t so surprising, seeing how he and Hanna shared a cute moment in the midseason finale of Ravenswood, but we wonder what brings him to town. Does this have anything to do with his near-death? Or perhaps his “unexplainable feelings” for Miranda?

As for our number one “A” suspect, Ezra has “clandestine meetings with Mona and Aria.” Hm. Why is Ezra secretly meeting up with Mona? Have these two been working together the whole time? Does he think the Liars might be catching on to his tricks? And why is he secretly meeting with Aria?! Is she somehow part of “A’s” plan?
