My speculation for the plot of the first episode of season 2.
>The pass out of the valley is almost thawed out. Anne is excited to look for a way to get back home.
>Hop Pop casually mentions, as a joke, that if Anne does find a way back home, she might get stuck in her own world for good and they would never see each other again.
>Anne has an internal mental breakdown over this comment.
>The next morning Anne is acting weird, trying super hard to be helpful. She's made breakfast for everyone and cleaned the house.
>She keeps calling Hop Pop "Grandpa", Sprig "Little Bro", and Polly "Little Sis".
>When questioned about her behavior, she insists that her name is Anne Plantar, and that she's lived in Wartwood with her family for her entire life.
>Hop Pop points out how that can't be true because she isn't a frog.
>Next scene is Anne emerging from her room dressed in a homemade frog costume.
>Hijinks ensue as the people of Wartwood become increasingly confused at Anne's insistance that she has always been a part of their community.
>Eventually Sprig figures out what's going on, and convinces Anne that she owes it to her parents to try to get back home, even if that might mean never seeing the Plantars again.
>At the end of the episode, the pass has fully melted. Anne and the Plantars leave the valley in their wagon.
