We are super excited about tonight’s new episode of Grey’s Anatomy (Season 9, Episode 22: “Do You Believe in Magic?”). We already know that the episode will feature One Tree Hill’s Hilarie Burton in a guest-starring role as a visiting craniofacial surgeon and a magician’s trick gone terribly wrong, but what else can we expect?

Jessica Capshaw (Arizona Robbins) has a few words for us. Yesterday (May 1), Jessica tweeted, “Tomorrow night’s epi....get ready!! Draaaaama!! Thrrrrrriiiillllssss!! *i wish u could have heard me sing "drama" & "thrills" as I typed this.”

There's plenty of drama ahead for Callie, especially when an old friend (and possible flame!) comes to Grey Sloan Memorial to help out on an emergency case. Here's ABC's full episode synopsis:

“The doctors reach out to Bailey but she continues to shut everyone out; after an incident with Ethan's grandmother, Owen fears the child could end up in foster care; and a new craniofacial specialist (Hilarie Burton) arrives at Grey Sloan Memorial Hospital to work on a young patient; meanwhile, a magician's assistant is rushed into the ER after a magic trick goes terribly wrong.”

Sounds good to us! We’re so ready for a little excitement, especially since tonight’s episode is the last one before the two-part “bold and shocking” Season 9 finale we’ve been promised. 

What do you think will be the “drama and thrills” in tonight’s episode?

Catch the next new episode of Grey’s Anatomy on Thursday, May 2, 2013, at 9 p.m. ET/PT on ABC.
