Yellowjackets has officially wrapped up its third season, with no word yet about a Season 4 announcement. This season saw a lot of changes in both timelines, as well as the deaths of a number of beloved characters. The teen timeline said goodbye to Ben (Steven Krueger) and Mari (Alexa Barajas) in ways that had been foreshadowed, while the adult timeline killed off Lottie (Simone Kessell) and Van (Lauren Ambrose) in ways that definitely had not.
