Talk:How the 'A' Stole Christmas/@comment-25547603-20141123142440/@comment-109.125.74.45-20141123145920

I think some time in 2B/endofA someone approached Mona, to join in her A game. Which led to Mona being more confident, joining the liars group and sending herself texts. Maybe it was even planned that she would reveal her A-ness as a betrayal to Hanna, (and why she continued that with Toby, for Spencer in season 3) but all in all it was a trick by the other A person.

Mona got sent to radley thinking she is still part of this super evil plan, while the other A started setting up camp and playing by her own rules.
