Maisie was Alex's college roommate, she is known to be bubbly and little dumb, she is everything Alex doesn't want in a college roommate, but Haley manages to convince Alex to let Maisie stay. Alex wanted a roommate who was like her, smart, a know-it-all. Maisie has been known to make a couple of inappropriate comments but all done unintentionally.
In "The Storm" Maisie is studying with Alex at the Dunphy house (and later at Jay and Gloria's) where she ends up admitting to Luke that she thinks he's really hot and could see herself making out with him under the right circumstances.
