The doctors go to investigate the music coming from outside and find a pipe band playing in the ambulance bay.
Meredith is waiting in line for coffee as Deluca joins her. Teddy and Koracick talk
about the food at the hotel they are staying at. Owen and Leo join them; it's
awkward.
Maggie and Meredith operate on Kiki; Owen and Alex operate on Colin but then run into some problems; Teddy operates on Lucille; Julian, Marvin, Seamus and the other pipe band members wait for news.
