A helicopter crashes on the roof, falling into the ambulance bay where it lands on Romano and causes a huge explosion. Pratt and Morris are pretty lucky: Romano had just fired Pratt and caught Morris smoking weed in the ambulance bay. Susan worries that Chuck was onboard, although it turns out he wasn't, even though he does have some internal injuries. He'll be fine though. Abby daydreams about what Carter's up to in Africa. Luka enjoys Thanksgiving dinner with Sam and her son Alex.
