Who do you think the tratior is that is working with Mona and the A-team?

i think the traitor is working with the A team then i also think their gonna tell someone about A and that person it gonna be the trator and go tell the As.

personally, i think it is Paige

i think alison is still alive and she's A

Alison's mom. She is hardly ever around for Jason. She I believe is on the board of hospital Administration-gives all pass access to come and go freely without too much questions asked. The body height,weight,frame build are a perfect match if you look carefully in S1EP6 I think that is when we first meet Alison's mom more closely. She is protecting Jason/and avenging Courtney. Thus Traitor to Alison.
