What happened last season of pretty little liars?

Hanna got ran over by "A" she's fine now though. She met a hot, homeless, bad boy, can't remember his name//: and they got really close, he crashed at her house for a while, she lost her virginity to him, but he apparentl was working with Jenna, but when he ended things cuz he had real feelings for Hanna, she found out, and he left. The gay friend's(cant remember name//: ) gf got sent to rehab or something, she started talking to the girl on the swim team, who happened to also be gay, and they kinda hit it off but she was ashamed to tell anyone so she said bye. Toby is n longer accused of murdering Alison, they suspect Spencer of it. But Spencer's sister's bf deffinitly has something to do with it. And he used to be sexually involved with Alison, the weekend before she disappeared. Aria's parents are starting to date again.
