tbh i don't get alison's relationship with cece.. i mean cece tells it like they were friends but how can you be friends with someone who kicked you out of university

you know how wren said something about ali pulling a stunt at a frat party that got cece kicked out of uni? maybe she was that girl someone pushed down the stairs in episode 18 of season 1 in that flashback.. we all thought it was Ian but I think it was Alison.. and then someone punches her in the face where she bleeds in last episode's flashback and she tells spencer that girls fight dirty than guys!!
There is definitely something suspicious about cece and her wearing the same clothes ali wore when she went missing and her lying to aria about her car being towed.
And I don't like this Melissa/Cece duo. They are up to no good.
