Former Greys Anatomy star T.R. Knight is back in Shondaland!

The actor, 43, has joined the cast of The Catch, which is executive-produced by Greys creator Shonda Rhimes, for season 2 and PEOPLE has the First Look at the actor in action on the ABC drama.

The Catch centers on private investigator Alice Vaughan (Mireille Enos), whose fianc Benjamin Jones (Peter Krause) conned her out of her money before sacrificing himself to save Alice from wrongful imprisonment.

Knight, who spent five seasons on Greys as George OMalley, joins the show as Alices brother.

Youre boyfriend is a conman? Knights character asks in the clip.

Fianc, thank you very much, Benjamin corrects him.

Whatever the status of their relationship, it appears things will get very Mr. & Mrs. Smith between Alice and Benjamin, who point guns at each other at the end of the promo.

Were not going to shoot each other, Benjamin says before giving his statement a second thought. Are we?

Season 2 of The Catch premieres March 9 at 10 p.m. ET on ABC.
