USC Trojan Marching Band

My baby's having a baby-Elizabeth Banks guest stars - Carla goes into labor and an excited Turk strikes up the band -- literally -- while escorting her to the hospital, but he still feels upstaged by Elliot's attempts to make Carla more comfortable. A scheme to make himself look like the hero backfires and Turk is in jeopardy of missing the birth of his child. Lucky for him the whole thing is mistakenly being broadcast over the hospital's closed circuit TV. Meanwhile, J.D. and Kim contemplate their future and the future of their child.

The med students are thankful when Cole identifies his true calling; Lucy finds her inspiration.
