Ryan Devlin is quickly becoming an ABC staple.

Already having scored roles on Grey’s Anatomy (as Mandy Moore’s husband) and Cougar Town (as Busy Philipps’ boyfriend), he's signed on for a part on Brothers & Sisters, too.

Devlin has been cast as a fun, smart, and precocious grad student in Kitty’s law class. Rumors suggest the former Mrs. McCallister takes a special interest in Devlin’s character.

This could be a serious thing, too. He's booked for at least four episodes of the ABC drama. Perhaps it just isn't meant to be with K's new handyman love interest Jeremy Davidson.

We'll have to wait and see, but more Devlin is always a good thing.
