On a snowy Chicago Thanksgiving, Carter enjoys a snowball fight and is surprised to learn about a Caribbean fruit poisoning from David, who confides he got his degree in Grenada. Mark hosts a turkey dinner for his father David, who keeps going on about World War II and kid daughter Rachel, whose 'patriotism' is way worse against British cook Elisabeth, yet Mark must leave them for a special patient. After getting up too late to do a shift, Carol 's water breaks on the train, but Luka finds her and brings her to ER, where she hates not being transferred to maternity being too far already.
