Last night, Kevin McKidd (Owen Hunt) live-tweeted the episode. About 45 minutes into the episode — right around when it came time to really say goodbye to Mark (Eric Dane), Kevin tweeted, "show is getting sad i know, was sad to film."
We're not surprised. The cast wasn't just saying goodbye to a beloved character — they were also saying goodbye to a valued co-worker.
Are you sad to see Mark go, too?
