Talk:How the 'A' Stole Christmas/@comment-79.112.255.226-20141003175437

Now I know why "A" killed Mona !

"A"s plan was like that : the girls shouldn't trust Alison, that way, it will be easier to get Alison.

Mona, Jenna and Sydney are the ones who know who "A" is. At the end of 5X03 and in 5X05 they met the person.

When the girls didn't trusted Ali anymore, Mona's role in all this was over. "A" owns the game Mona made, making her useless.

"A" is cruel. She killed Mona, because Mona's done with what "A" wanted. This person infliltrated "Mona's army", and convinced them that Alison is "A".

Then, Mona takes the girls to Radley, in order to get information about Bethany. They found out the proof on who "A" is, but Mona thinks is Ali. Because "A" is someone the girls know, they would've realized who she is, not Alison definetly.

That's why Mona was killed.
