Does anyone know what happened to Krista and why she's not in season 3?

She was just an intern, wasn't she? I mean, so was Paul, but he was actually hired by the hospital.
Maybe her internship is over?
But yes, I was wondering where she'd gone, too. It's weird she hasn't been mentioned. But maybe since Drew's back, and they were buddies, maybe she'll come up at some point.

I remember vaguely them saying they only had enough room to hire one of the interns krista, or Paul. Then next we see Paul no krista so I’m sure that’s the reason she’s gone, so they threw that line in to make her absence make sense? Idk I may be wrong, but I am just going by what I remember.
