This week: The Temu Newsies strike again as Ray and Gates leave the ER to help a pregnant teenager, Abby finds out what Luka has been doing to Ames, the Morris growth arc continues as he spends more time with Hope, Sam works to find out what really happened to an abandoned homeless woman, Neela is getting all sorts of attention (some professional, some creepy), and County General celebrates Christmas in a variety of ways.
