For her part, Kristen Hager is coming to Med to play Dr. Stevie Hammer, who will be helping fill the void specifically in the ED as an emergency room attending, who is a brilliant doctor with scrappy sensibilities.
She doesn’t seem to be a direct replacement for Natalie, as Nat specialized in pediatrics, but another female doctor is on the way!
It should definitely be interesting to see how she fits into the ED with so many changes, especially since it seems she’ll be spending a lot of time in the ED with Steven Weber’s Dean Archer and the rest, almost certainly including Will Halstead despite that Season 6 finale cliffhanger.
