Pt 1! Great questions! Personally I’m a huge Beth x Benny fan so I want them to end up together. But if we’re going by what is suggested in the story, there’s a couple things that could happen.
First I bet Beth and Benny would fix any lose ties in their relationship and forgive each other, leading to either a platonic relationship or romantic relationship. I think out of all men, Beth and Benny have the most probability to end up together. I think they match each other’s energy and passion, and they seem to be on the same level mentally/intellectually.
But the there’s Townes, which if I’m remembering what happened in the show correctly, I think their last encounter was a platonic one. Personally I think they are nothing more then good friends, despite Beth’s crush she had as a schoolgirl and up into adulthood. But you never know, Beth and Townes could end up in a relationship. However, something about Townes’ sexuality that was alluded to in the series makes me think they won’t end up in a romantic/sexual relationship. (I’m not completely sure what his sexuality is, but I would guess he is unlabeled bi/gay/pan/queer)
