Guys Alison was never hit (the doctor didn't find anything on her head lol), I think she was part of  the 'Agreement' between Peter Hastings and Jessica Dilaurentis (don't you remember Peter reminding Jessica about their agreement?). That would explain why Jessica was killed once Alison was back (The agreement was broken because Ali was back! That's why peter told Jessica at the PD 'Do we still have an understanding?').

This is why 'Two can keep a secret if ONE of them is dead'

I got this theory from here
