Ok I just finished episode 7 and I have no idea who Mona is

I thought it was Angie Bolen which I personally ADORE, I love her son as well, he's so nice and HAWT, they maake a graet mother-son couple. The dad..errrrr, don't like him that much.
I believe this is the best season of the show since the first one, episode 4 was A-MA-ZING, Gaby rocks the show, and Katherine should just go away, get a shrink or something, that storyline is awful.
