Mona may know exactly what she's doing, but it certainly seems like she's a far cry from sane, don't you think? Acrtress Janel Parrish has said that her character is definitely a bit on the "crazy" side - and Pretty Little Liars writer, Joseph Dougherty agrees, who spoiled on Twitter yesterday that Mona will be returning next season.
Working on #PLL Season Four. The other writers seem to think Mona is crazy. I really don't know where they get that from. Certainly not me.

Ha. What level of "craziness" do you think Mona will achieve in season 4?
