So Kristin's got something up about the Grey's premiere, in which she says:
Derek is stabbed later in the episode, and Nurse Rose (Lauren Stamile) has something to do with it. That lady is full-on Looney Tunes.
Of Ausiello's five potential injuries to befall McDreamy, the stabbing was something I didn't even entertain. Now, I'm really confused.
What Kristin doesn't specify, however, is with what Derek gets stabbed.
Could be a paper clip.
Could be a mechanical pencil.
Mae says could be a scalpel, accidentally. One of those things that's an accident, but probably an accident that wouldn't have happened if Rose wasn't so angry. I mean, I highly doubt Rose is going to go all American Psycho on Derek Shepherd, but she might be annoying enough to let the knife slip 'cause she's pissed.
Still--accidental. Not life threatening.
