If you don't know Jason Ritter, he's an actor who's also the husband of Melanie Lynsey (Shauna). He was cast for season 2 of Yellowjackets for a small role as he's only guest-starring and did one episode. But we still don't know who he plays.

In an interview, Melanie is asked about his role but says she's unable to give any details at all which means that if she did it would be a spoiler. Seems like it will be significant to the adult plot line. It's unlikely he joins the teen girls unless it's a flashback or hallucination obviously due to the circumstances.

Who do you think he could be playing?
