With his husband by his side, he signs-up for an operation that will need plastic surgery. The doctor in-charge (possibly Dr. Avery) informs him about his course of action.
Apparently, the doctor's strategy is to remove a portion of fat from his buttocks then transfer it into his lips through injection.
Ha! Looks like we're in for another funny episode, Grey's fandom!
Don't dare miss the airing on Nov. 7 at 9/8c.
