Mona's motive is plain stupid if I got it right...she was jealous of Hanna that got back with 3 other girls but those A messages brought them back together
Idk we still haven't found out who killed Ian and Garrett so ....
@popboi__ Marlene herself said Mona is and always will be original A. Once this new person stole the game from here in season 3 she wanted to expose him/her but didn't succeed
Andrew is being painted way too obvious to actually be involved in the grande scheme of things. Although I'm pretty sure he's the one who maced Mike and tied him up
So I rewatched the episode again amd found a new plot hole ... Leslie said she and Mona became close friends last summer but wasn't Mona at Redley at that time ?
