Details about Radnor's character are being kept under wraps, but it seems Meredith finally agrees to let her matchmaker patient awaiting a kidney transplant help restore her romantic mojo, so the two will go on a blind date in Thursday's episode.
And the other doctors are, naturally, curious as to who it could be - or, at least, what's going on.
"What happened? Are you going to a funeral?" asks her sceptical sister-in-law, Dr. Amelia Shepherd (Caterina Scorsone).
And Dr. Alex Karev follows suit, remarking: "What's wrong with you?"
"Oh my god, you have a date", Dr. Maggie Piece (Kelly McCreary) says.
Radnor, who is best known for playing Ted Mosby on How I Met Your Mother for nine seasons, most recently starred in the short-lived show Rise. News, the 44-year-old actor is set to appear as the new love interest for Dr. Meredith Grey (Ellen Pompeo). And yes, she's a surgical marvel with new, game-changing medical ideas she'll be pursuing.
"What we're doing that's different than what we've seen is, she's gotta go on dates". And the one-two punch of meeting Nick Marsh awoke a desire in her that she can't put back to sleep. Noting that her romance with Derek was "pretty epic", Vernoff said there is a message "to all of the men and women who have loved and lost, whether they've lost to circumstance or to death, yes, to love again is possible".
