Grey's Anatomy Season 10 is already shaping up to be a thrill ride! 

Thanks to an earlier tweet from Ellen Pompeo, we already know the Season 10 premiere is going to be an emotional roller coaster, but now we have more intel on what to expect from the ABC drama's tenth season — including two new faces! Being Human's Bobby Campo and Hellcats' Heather Hemmens have both booked recurring roles on Grey's Anatomy, reports The Hollywood Reporter.

Bobby will play Brian, a "young and dedicated fireman who is introduced after the scene of a major accident." He's also engaged to Sasha, played by Heather, a "tough cop with a good heart who is also involved in the disaster." 

There's no word on whether the major accident Brian and Sasha find themselves involved in is the bus explosion featured in the emotional Season 9 finale, or if it has something to do with the "twisted sexual/medical case" Grey's writer Tony Phelan teased earlier this month. Of course, Grey Sloan Memorial still has to put out the electrical fire that was a result of the superstorm in the finale — and could possibly be the death of Richard Webber! But the fire won't rage for long. We know there will be firefighters on hand in the premiere episode.

Either way, it’s exciting that the show is gearing up for its milestone tenth season. We now know that it premieres on Thursday, September 26, 2013 at 9 p.m. ET with a two-hour episode, which means it’s going to be extra crazy.

Grey's Anatomy returns with a two-hour season premiere on Thursday, September 26 at 9 p.m. EST on ABC.
