The Hollywood Reporter interviewed Grey’s Anatomy creator Shonda Rhimes and at the end of the interview the Grey’s cast say what their favorite episode of the show has been. For Justin:

Justin Chambers (Alex Karev) Season 9’s “Perfect Storm”
“It’s nice that Alex has met his match in Jo. She can relate to growing up with struggles but getting through them and becoming a better person.”

Below are the photo captions with quotes from Justin and details about Alex’s story line.

Alex’s ‘Person’

Camilla Luddington, left, takes direction from director Rob Corn as her on-screen love interest Justin Chambers looks on. In the 200th, Alex invites Jo to the gala because, as Luddington says, “He doesn’t want to schmooze with rich people, which is Jo’s nightmare too.

“He is bringing her to help him and he is abandoning her throughout the whole episode,” she says. “He’s running away and he’s not present, and she’s feeling super stressed about it. So even in that tension between them I feel so invested in their relationship it breaks my heart to see them having problems.”

Luddington’s co-star Justin Chambers thinks Alex and Jo are really MFEO. “Sometimes it’s not about opposites attracting. Sometimes you need to be cut from the same cloth to move forward,” he says. “I think that they understand each other really well, but I think that she adds an excitement to him — a spark.”

Laughter at Grey Sloan Memorial?

Gaius Charles, Sarah Drew and Justin Chambers share a light moment between takes. Chambers is one of only a handful of original stars left on the Shonda Rhimes medical drama and believes departing co-star Sandra Oh should wind up “running a hospital somewhere.

“She should find happiness even if it’s through work,” he says.
