The winter finale of "How to Get Away with Murder" is finally here, and we can tell you: You are not ready to find out who's under that sheet.

With two people still unaccounted for, Laurel (Karla Souza) fighting for her life in the hospital, and Frank (Charlie Weber) holding a gun to his own chin, it's hard to see how only one person can be losing their life on Thursday (Nov. 17).

We talked with showrunner Pete Nowalk about the decision to kill off a major character, and what fans can expect the fallout to be from this death.

"It was a gut decision," Nowalk says of picking which character ends up under the sheet. "It's sort of like looking for the thing that's going to torture the characters most ... what resonates most painfully with the characters?"

What's been real torture is anticipating who's alive each week, and theorizing about the remaining characters left unaccounted for. Nowalk says that amid all the thousands of theories about how the night of the fire plays out, a few fans have managed to get it right -- he just won't say which ones!

"I think the people who are really hardcore fans ... they're savvy," Nowalk says. "It's a puzzle, it's not easy."

Beyond all the heartbreak at losing a beloved member of the team, if you're expecting to feel a sense of relief at finally knowing who's under that sheet, you might want to curb your expectations there. You should know by now that as soon as "How to Get Away with Murder" closes the door on one mystery, Pete Nowalk opens a window somewhere to let another one in.

As always, the final few moments of the episode turn the whole world on its head again.
