Adam Busch

You gotta love Shonda Rhimes’ devotion to the Buffyverse! Shonda’s love of Joss Whedon is famously one of the reasons she started writing for television in the first place, and she’s long hired Buffy stars like Seth Green, Amber Benson and Nicholas Brendon to guest on her shows Grey’s Anatomy and Private Practice.

So which Buffy boy is heading to Seattle Grace now? Here’s the exclusive scoop:

Adam Busch, who us Buffy fans will remember as Warren, one of the dastardly Geek Trio who contributed to the death of Amber Benson’s Tara is set to guest in the Jan. 13 episode "Start Me Up." (Busch and Benson later dated in real life, BTW, and Benson guested on the Nov. 4, 2010 episode of Grey’s Anatomy.)

Busch is playing a first-year resident who must shadow Dr. Cristina Yang (Sandra Oh). At the moment, the role is planned for one episode.

You know what this means, don’t you? That fishing-trip psychological breakthrough stuck, and our girl Dr. Yang is finally getting her medical mojo back. Woo to the hoo!
