Fighting COVID had been Koracick’s main storyline for the better part of Season 17, after being part of an unfortunate love triangle with Teddy Altman and Owen Hunt.
The love triangle seemed to have lost its third angle by the end of “Tradition” anyway, with Owen and Teddy reuniting.
That’s despite the fact that Teddy slept with Tom on what was supposed to be her and Owen’s wedding day (on a voicemail for the whole OR to hear), and despite the fact that Owen said some pretty heinous things to Teddy about her former relationship with Allison, but that’s none of my business.
