Where to begin? We left off halfway through Season 3 back in October, and finally FINALLY the resolution is here. First off, Aria is none too happy with Garrett’s tale of her father being with Alison the night Ali died. She can’t believe Spencer would believe him. No one is accusing him of being “A” or saying he was on the train.  Also, Mona is back at school. Hopefully, the Liars’ idea to be friends with her is a good one — keeps your enemies closer and all that. She’s not “A” so that’s a wash…but who is? Hopefully all will be revealed when  “Pretty Little Liars” returns to ABC Family Tuesday, Jan. 8, 2013.
