The boards: According to the press release about the episode, "the residents travel to San Francisco for the oral board" this week. Stressful! We know one resident won't pass the Boards, though it sounds like we won't find out who the unlucky person is until next week.

Obstacles to success: According to TV Guide, one doc will arrive late and a section of the Board because of it, and another will have a "medical-ish" emergency. Ellen Pompeo (Meredith Grey) has dished that Mer faces a "huge obstacle" in the middle of the boards, which makes it sound like she'll be the one with the emergency. In this preview of the episode we see that she is throwing up prior to the test, so maybe that's related (or maybe it's just nerves).

Cristina back to form: Cristina's (Sandra Oh) proctor will be William Daniels of Boy Meets World fame, which is awesome. And according to Sandra Oh "people will be quite happy with seeing Cristina back to form," during the Boards. "I call [this] episode 'Hoisting Oneself on One's Own Petard.' It's really funny."

Alex's guilt: According to the press release, "Alex Karev [Justin Chambers] feels guilty about being away from the hospital when Tommy's health takes a turn for the worse." We wonder if that will affect his performance during the test?

Jackson and April: As we see in the previewApril Kepner (Sarah Drew) and Jackson (Jesse Williams) hook up this episode. According to Sarah Drew, April is freaking out prior to the Boards (understandable) and it sounds like that's part of what fuels the hookup. Sarah hints that "there’s also something very cool revealed about April at the end of the episode," and mentions that "there's a lot of confusion between the two of them regarding what the relationship actually is after they hook up."

Slexie action: In this sneak peek of the episode Mark (Eric Dane) tells Lexie (Chyler Leigh) he "needs" her, though he's only talking about a medical case...though we're sensing a lot of subtext. 

Richard's sparks: According to the press release, Catherine Avery (Debbie Allen) is back, and "sparks fly" when Richard [James Pickens Jr.] bumps in to her "at the hotel." After last week, poor Richard deserves a little happiness!

Teddy vs. Owen: Finally, the press release says, "Bailey [Chanda Wilson] intervenes after Owen [Kevin McKidd] and Teddy [Kim Raver] get into a heated argument about their young car crash patient."

Catch the episode on Thursday, April 26 at 9 p.m. ET/PT on ABC.
