She left because she lost her steroids in a game of snap against Jay.:h
Her lack of steroids would account for the adut acne she's been suffering.
And his winning of steroids would account for Jay's renewed cheeriness.
Who cares anyway I'm glad she's gone all she did was mope around, bad mouth Aaron & make Faye miserable.
She is so obviously jealous of Faye. Faye got the looks & the semi level head. Gem got the scowl & the spots.
