'Grey's Anatomy' Season 10 Premiere: Bobby Campo And Heather Hemmens Check In For Disaster

Two familiar faces are checking in for the two-hour "Grey's Anatomy" Season 10 premiere: Bobby Campo, from Syfy's "Being Human" and Showtime's upcoming "Masters of Sex," and "Hellcats" alum Heather Hemmens.

According to, who first reported the casting news, the two will play an engaged couple -- he a fireman named Brian, and she a police officer named Sasha, both of whom are involved in a disaster in the big Season 10 premiere (Thurs., Sept. 26 at 9 p.m. ET on ABC).

A rep for ABC confirmed the news to The Huffington Post, saying they are both set to appear in the two-hour season premiere. No word on THR's claim that there's "potential to continue beyond" that.

In the Season 9 finale, the doctors of Grey Sloan Memorial Hospital were knee-deep in superstorm problems and completely powerless. (Literally. All the power went out.) So, of course, Meredith went into labor and needed an emergency C-section, and then some; Arizona and her new pal Lauren got all kinds of cozy, essentially breaking Callie's heart; Jackson and Owen almost died saving kids from an explosive bus crash fire; and then we actually (maybe, probably) said goodbye to one of our original Seattle Grace docs.

To hear that there's another "disaster" coming -- a "major accident," according to THR's intel -- raises some questions. Is it the bus crash that happened right outside their doors? Or is something else big about to happen? We know Shonda Rhimes likes to do it up big for finales (see paragraph above), but could Season 10 be shaping up to be all action, all season long?
