It's so funny. I originally was a little worried that Will, who wasn't really in the show much last season, would be a weak link now that he's one of the main boys again. But the actor is killing it.
I don't like the image of a jealous El just because she's heard Mike trying to contact her for a year. She knows how much he still cares and that he hasn't replaced her. Although I do understand how emotions are hard to control - especially for a teenage girl.
