'Pretty Little Liars' Recap: A Death Comes Undone

It's Halloween time on Pretty Little Liars, which can mean only one thing: crAzy reveals.
This particular episode almost served as two shows in one, with Aria, Hanna, Emily and Spencer in Ravenswood as they figure out where their dear friend Alison -- who they've just found out from Mrs. Carla Grunwald may be alive -- and Caleb making his way into town with new friend Miranda.
