Most of the attending physicians of Seattle have already seen Addison Montgomery naked. Who hasn't? And more importantly, who still wants to? F/F. Meredith Grey/Addison Montgomery. MerAdd. Meddison. Rated E for Explicit. Addison is the go-to for adultery. How Derek found out. Meredith makes questionable decisions that sometimes turn out. Headfuck love square. Gay panic is resolved.
