Anyone want to give me a recap?

Lets see........ I'll start with the beginning of the season. All of the girls thought that Ian killed Ali but then were sent a note from a so come to a cemetary. They ended up seeing the video of the night she dies that she made with ian, but it was continued to find that Ian did not kill Ali. also their old friend garrett is back in town and is now a police officer. He is secretly dating Jenna but they recently make it a public relationship.... and then Jenna broke up with him, and no one knows why o how. Also, Ren is back in town and Spencer and Toby break up and toby thinks its because of him. Then toby leaves and comes back later with Jenna after her surgery. He is mad at Spencer and keeps giving her attitude. Jenna takes off the bandage from the surgery on her eye and says that she cant see..... but later te find that the surgery did work and she can see, but no one knows. Also, Maya came back and is still smoking illegally. Later she asks emily is she will go with her to run away to cali but emily says no, and maya runs off on her own. emily goes to the bus station and the worker says that he saw her but she did not go on the bus but instead she got into a mysterious car. Also.. now garrett and melissa are dating which is a surprise to all of them. Another surprise is that Alison comes to Spencer in the middle of the night and takes a pill from the bottle and leaves the lid open. Spencer thinks its a dream but wakes up to the door being open and the pill bottle uncapped. She gets freaked out. AT the end of the episode... Garrett is arressted for the murderer of Alison DiLaurentis. In the successivo episode, 'UnmAsked', we will find who A is!!!!!
