Been re-watching season three of Pretty Little Liars and it occurs to me that CeCe isn’t someone to count out of the “A” team. The biggest clue, when the girls first meet CeCe.
Somehow only Spencer, Aria and Emily are the ones to meet them while Hanna goes to school. The clue here or easter eggs according to Marlene King, is when CeCe mistakes Aria for Hanna.
The shop lifting didn’t start until after Alison went missing. Hanna and Mona did this together when they became friends. If CeCe knows this, then how? Don’t count her out yet guys, trust me.
