Coincidence or Fate?

Quinn Fabray; a single mother and Santana Lopez; a single brunette, meet in a broken elevator at a hospital one day. They notice an instant lust for each other, and leave hoping to see each other again, not realizing it would be sooner than they thought. Was it coincidence or fate that brings them together in that elevator? AU (Don't think it's my best summary, but give it a try)
