Spoiler:

I suspect Melissa, something fishy is going on with her, feel the same way as I did with her like I did with Mona

Oop, you'll have to wait and see, you find out who red coat is sometime in the second half of season 4, I think you'll be surprised

Also if Alison was redcoat, why was she visiting mona?
