Honestly? Not really. There are characters that are on the bench right now and might come back in future (Pickman, Kalar,) and I'm curious about what returning to them would be like, but generally when I'm done with a character it feels nice to put them down and move on. To me, the characters live in the season - that's where they go - and outside of that space there's not much I can (or want to) do with them.
