Characterization and Plot Discussion?

Hi! Since Imzy is better for discussing things than tumblr, I thought it might be nice to talk about the characters and how/what we're writing, or wondering about :)

What characterizations do you like? What are tropes you like or dislike for winteriron? Plot ideas? Things you would want to write, but can't for some reason?

I am currently planning to write some short things in a 616 AU (because winteriron should get more Identity Porn). By now I am so used to MCU Bucky, that characterization for comic Bucky is hard for me, though. Would he feel guilty for what he did as WS? I think the does, he just doesn't try to show it. Would he be worried about hurting friends, after he discovers there are still triggers?

I also really like the idea that MCU Bucky tried to stay away and out of the fighting and might actually not want to fight anymore.

What do you think? Are there other things/ideas you like?
