Below is the first promo for next week's episode of Grey's Anatomy, "Give Peace a Chance." The new episode will in fact air next week, despite previous reports of it being a repeat.

The tension we've seen building between Derek and the Chief all season long heats up in a big way next week when Derek wants to do a risky surgery to save a SGH lab technician.

All we've got to say is that we're excited for a Derek-centric episode, and happy that at least someone has been standing up to the Chief, who seems like he's steering a sinking ship.

Check out the promo below and see what you think ...
