ENTERTAINMENT WEEKLY: How did the cobalt poisoning story come about?
It felt like the actor had earned the right to play a story line this juicy.

But for the actor, it’s been a really exciting season.
We loved it for all of those reasons.
but every character in the show goes, “Oh my God, no, not Richard!”
It gives everybody something exciting to do.
It was so painful to watch Richard, of all characters, lose his mental capacity.
You don’t see that represented a lot on TV, and we loved that spin.
Obviously, this wasn’t originally your finale, but it almost felt like it was written that way.
What was your reaction when you realizedthisepisode would be the end of your season?
We got so lucky.
And then it became the season finale.
I do think we have to reset, I don’t know to what degree.
It was a relatively mild episode that followed an episode that was huge.
So for sure we’re going to have to reconsider a lot of things.
Just hey tell me we’ll get more Jo [Camilla Luddington] and Schmitt [Jake Borelli].
I love that dynamic!
You guys also delved a lot more into Koracick this season…
He is a complicated character.
What I love about that character is that we’re saying “yes, and.”
The big cliffhanger now is the Teddy-Owen wedding.
Culturally, if a woman cheats, she’s written off as a whore permanently.
