Mercy West residents invade Seattle Grace and we don't like them at all! As Lexie says, "They're aggressive, they're vindictive and they are not team players!"
"They're like locusts, feeding on our surgeries," says Meredith, who's recovering from having donated her liver. She urges her friends to fight for surgeries, but Cristina sighs, "I don't know what I'm fighting for anymore."
When Jackson, a Mercy West resident, suggests they split the ER into zones, Owen likes the idea. So each Seattle Grace resident is paired with one from Mercy West and we don't have to wait long for the sparks to fly.
