If Mona knew that Alison was alive and hated her, then why did she give ups her game to a blonde girl in a Red Coat? Who did she think it was? If she suspected Alison to be A in season 5, shouldn't she have suspected in season 3 that that if Alison is alive and a bigger villain than Mona, she might as well be Red Coat?
