According to Entertainment Weekly, McKidd would play a doctor who comes to Seattle Grace after a stint working in Iraq. While the report doesn't say the role would be permanent, it is described as a "long story arc."
I just have one request for the folks at Grey's: Could you somehow make him a Scottish doctor who happens to land in Seattle? Because, while McKidd is attractive with any accent, his natural Scots brogue is — if I may be shallow for just a moment — really, really darn hot. We could call him McScottie!
I think the Grey's ensemble has been lacking something ever since Isaiah Washington left the show, and while adding Brooke Smith as Erica Hahn helped some, it didn't completely fix the show's energy. Could McKidd be the missing link? Weigh in on that — and any hot Scottish doctor fantasies that you might care to share — in the comments.
