Pete's also treating Katie, a pregnant woman with a history of psychotic behavior. But she's on her meds now and ready to have her baby. Except, when Dell performs an ultrasound, it reveals that the fetus has died inside her. Even worse, Katie refuses to accept the truth. She swears her baby is alive and kicking and runs out of Oceanside. Oops, looks like someone needs new meds.
Then, Dell gets a visit from his ex-girlfriend Heather. She's finally off drugs and has a great job. However, that job is going to take her to St. Louis—and she wants to bring their daughter, Betsy, with her. Unsurprisingly, Dell argues that Betsy has to stay with him, but it looks like a fight he unfortunately can't win.
Back at St. Ambrose, Noah approaches Addison. Isn't he stalking her at this point? Anyway, once again he professes his undying love for Addison, who remains calm and professional. But, after the encounter, Addison runs to Madison to tell her she has to drop her as a patient with the excuse that she's too busy to keep running to the hospital. Morgan is heartbroken since she likes Addison so much.
Figuring he's lost his fight, Dell knocks on Heather's apartment door to see if they can't work out some sort of visitation schedule. He pours his heart out through the door, but nobody answers. When he peeks in a window, he sees that the place is devoid of furniture and people. Heather has stolen Betsy!
