Grey's Anatomy First Look: Avery Suits Up With Mystery Date, Der and Mer Reunite For [Spoiler]

The return of Grey’s Anatomy on March 15 (ABC, 9/8c) looks to be chock full of big developments: Avery suits up with a mysterious date, who is most definitely not Lexie, and his mom Catherine (Debbie Allen) is back with a new crush, but this one is very familiar to viewers: Dr. Webber!

But who is the lovely lady on Avery’s arm? That would be a urology fellow (played by Outsourced‘s Rebecca Hazelwood), who has come to Seattle Grace with Catherine.
Elsewhere, Summer Glau continues to torment Cristina with her prettiness as the doc grows increasingly suspicious of Owen’s activities, and Derek and Meredith make a big move towards trusting each other again when he convinces her to work with him on a case.
