Guess who’s coming to Seattle Grace-Mercy West in an upcoming episode of Grey's Anatomy? George Feeny (William Daniels) from Boy Meets World! Yes, Cory and crew’s old mentor will play a pivotal role on a very important episode of Grey’s.

TVLine reports that “Daniels will play one of the doctors overseeing medical boards being taken by the Seattle Grace residents.” Of course, our faves aren’t all taking the exams in the same room, so which doctor does William get to proctor?

Sandra Oh (Cristina)! The actress tells TVLine, “It’s actually really hilarious!” She continued, “I just shot the entire boards episode with the wonderful William Daniels, who played Cristina’s proctor. It was phenomenal to be working opposite him.”

Since William’s episode is supposedly “one of the ABC drama’s final episodes of the season,” it’s safe to say that there will be heightened emotions throughout, but it’s nice to know we can expect some comic relief as well.

Grey’s Anatomy returns with an all-new episode on Thursday, April 5 at 9 p.m. ET/PT on ABC.
