What is madness and what is divine? While in triage after a vicious attack, the Yellowjackets are left to suss out the best of their worst ideas. Shauna dabbles in some light cyberstalking.

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. Season finale.
