It’s time to finally resolve those 2015 cliffhangers, Shonda Rhimes! When “Grey’s Anatomy” concluded the first half of Season 12 in November, the mastermind behind the long-running medical series made sure to leave  fans sitting on the edges of their seats following the show’s drama-stuffed midseason finale.

From Jo’s (Camilla Luddington) lingering response to Alex’s (Justin Chambers) marriage proposal, to the reveal that Owen (Kevin McKidd) has a sister, audiences – including ourselves – couldn’t wait for the return of the ABC series. But while some questions will be answered in the winter premiere, others will be raised.

According to the newest “Grey’s Anatomy” promo video, which celebrates the return of TGIT (Shonda Rhimes’ three, Thursday-night shows), Meredith (Ellen Pompeo) will find herself struggling to breath in an upcoming installment. In the 30-second trailer, viewers can see Meredith, along with someone who appears to be her colleague, laying on the hospital floor covered in blood. And from the pained look on Mer’s face, it’s safe to assume the worst … after all, this is “Grey’s Anatomy.”

A clip from another scene of the trailer shows Meredith sporting an oxygen mask and some nasty lacerations on the right side of her face. But what exactly caused Meredith’s injury? Well, fans will find out when the new season returns in February.

During an interview with Entertainment Weekly, Rhimes dished that the first episode, directed by Denzel Washington, “is extraordinary and very, very powerful.”

“It certainly puts us on a path for the beginning of the second half of the season,” the executive producer dished before revealing that cast and crew have “been having a blast” while filming the second half of Season 12.

Is it possible that Rhimes could have been hinting that an explosion might take place in the premiere episode? Although that storyline has already been used in the past, we’re thinking a potential bomb might explain why Meredith and her colleague were laying injured on the floor.

What do you think caused Meredith’s injury? Sound off in the comments section below with your predictions and don’t forget to tune in to “Grey’s Anatomy” on Thursday, Feb. 11, at 8 p.m. EST on ABC.
