Intern Jo keeps getting vomited on by a guy who looks like Santa Claus. The perpetually puking patient probably isn't the real Kris Kringle though. Owen says the guy has been coming in for years. He wants him discharged pronto. That's something Jo isn't ready to do. She cleans him up and runs some tests. There's no sign of illness.

Suddenly, the guy is a jolly old elf who no longer has to live with his longtime affliction.

Bailey hatches a plan to push the still-housebound Arizona into snapping out of her funk by asking for help with a pediatric case. Arizona is led to believe that Intern Leah (who is way hung up on Alex) left the patient's chart outside her front door. This forces her to strap on her prosthetic leg to retrieve something that was never there. That's because Bailey never sent it. The diabolical plan to lure Arizona into the hospital works brilliantly. Just like that, she's back in the game.
