So many questions answered, yet so many remain heading into the season finale of Showtime’s “Yellowjackets.” Ahead of this Sunday’s finale, a new promo below teases the fallout from the insanity of “Doomcoming,” the penultimate episode that sent the characters teetering past the threshold of sanity.

In the season one finale: “On the night of their 25-year class reunion, the Yellowjackets navigate damning evidence, false alibis and a dubious attempt to “heal.” In the wilderness, the Doomcoming fallout finds everything firmly off the rails as simmering resentments come to a head.”

The episode’s title, “Sic Transit Gloria Mundi,” is a Latin phrase that translates “Thus passes the glory of the world.” What’s intriguing about that is that it was used in papal coronation ceremonies, so it seems likely that we’ll finally see the crowing of the Antler Queen in this episode. Also interesting to note is that the finale is directed by Eduardo Sánchez (The Blair Witch Project).

Will all questions get answered? Probably not, but luckily Showtime already renewed “Yellowjackets” for a second season. That means it’s not too late to catch up to one of the most riveting mystery box shows in recent memory.

The series was created by Ashley Lyle & Bart Nickerson (“Narcos”), described as being “equal parts survival epic, psychological horror story and coming-of-age drama.”

Melanie Lynskey, Tawny Cypress, Christina Ricci, and Juliette Lewis star.

“Yellowjackets” airs Sundays on Showtime.
