Grey's Anatomy is about to reveal Derek Shepherd's fourth sister
Get ready, McDreamy fans. Apparently, there’s another Shepherd out there who’s about to arrive in Seattle.
EW has confirmed that Grey’s Anatomy is on the lookout for an actress to play Kathleen, the fourth sister of the late Derek Shepherd (Patrick Dempsey). She will be introduced in a season 15 episode that will revolve around Amelia (Caterina Scorsone), one of Derek’s siblings. The other sisters who have appeared in the past are Liz (Neve Campbell) and Nancy (Embeth Davitz).
The existence of Kathleen, a.k.a. Kate, was first mentioned in season 3. TVLine was first to report the news.
There’s not much more to say about Kathleen other than she, like her sissies, has her doctorate. But she’s a psychiatrist.
It’s been years since a living and breathing Derek walked the halls of the hospital; his character was killed off in 2015. But in a special Dia de los Muertos-themed episode that aired in October, viewers saw him and his best friend Mark (Eric Dane) watching Meredith walk out the door.
“I had just watched the movie Coco with my daughter, whose name is Coco, and I was so moved to discover the idea that there is a day when our people can come back to us,” executive producer Krista Vernoff told EW at the time. “So [writer] Kylie Donovan pitched it and I said, ‘Let’s have [Meredith’s] dead people come visit.’ We talked about it for four months with the visual effects people. You have to really plan a sequence like that. What I love about that sequence is that we have combined some old footage that aired, some old footage that didn’t air — we pulled old dailies — and we shot some new stuff. Doc, we shot. Ellis, we shot. And the idea of that, for me, is that we don’t know if this is in Meredith’s imagination or memory, or if it’s actually happening. For whatever anybody believes, there is a little bit of something.”
Grey’s Anatomy airs Thursdays at 8 p.m. ET on ABC.
