What to Expect from Grey’s Anatomy Season 21 Episode 12: Tom Koracick Returns, Teddy and Owen Hit a Breaking Point
Tom Koracick is back to cause trouble on Grey’s Anatomy Season 21 Episode 12, “Ridin’ Solo.”
When Meredith and Amelia present a funding proposal for their Alzheimer’s research, they learn that someone else has beaten them to the punch. It appears that person is Tom Koracick, according to the promo video for the episode.
Meanwhile, Teddy and Owen reach a breaking point in their marriage. Could they decide to change the terms of their relationship and try having an open marriage?
Based on clues we’ve been given so far this season and the introduction of Sophia Bush’s Cass Beckman, it’s possible.
The hospital also hosts a group of prospective interns, and Jules and Dr. Beltran have an awkward encounter.
Here’s everything you need to know about this episode, including the air date, cast, promo, and how to watch.
