Another original "Grey's Anatomy" character might be in danger, and fans want answers.

The threat emerged not in last week's episode itself, but in the promo for this week's, Episode 11, "(Don't Fear) the Reaper." The short clip showed Dr. Miranda Bailey (Chandra Wilson) telling a nurse that she might be having a heart attack. So far, we don't know whether or not her health situation is truly dire, but with all the key characters we've seen killed off over the years, we wouldn't put anything past show creator Shonda Rhimes.

We do feel somewhat comforted, though, by what Wilson recently told EW. She was purposefully vague in order to not spoil the episode's plot, but her hints did seem to indicate that Bailey will be sticking around and just needs less stress in her life.

"Let's say Bailey has been stressed," she said. "Is Bailey leaving? I think this is the right thing to say: Bailey's been stressed and needs to take care of herself."

Wilson went on to tease more of her storyline, highlighting that this episode will show how heart disease symptoms are different for women than they are for men. Additionally, she pointed out that the ER experience can be harder for women, and that "Grey's Anatomy" will show "how to be taken seriously when you walk into an emergency room situation so that you can be properly diagnosed and properly treated."

It could be wishful thinking on our part, but that seems like knowledge the show could pass on without killing off one of its oldest and most beloved characters. Long live Dr. Bailey!

"Grey's Anatomy" airs Thursdays at 8 p.m. ET/PT on ABC.
