Leah is sent up to the observation room to keep an eye on Richard, who believes she should be downstairs learning. But there's no way the intern is leaving his side. Bailey and Meredith are out of options to save Adele until Richard barks instructions over the intercom. His suggestion works. Adele is out of the woods and grateful to see Richard by her side when she wakes up.
Cristina and Owen never make it to Bailey's wedding ceremony. They are too busy making love in an on-call room.

He blames himself for the crash. The leader of the gang, a feisty lady who goes by the name of Gasoline, wants to see Stuart. Owen fears she wants to punish the guy. Security!
