Tesserae (слэш)

For the ImagineTonyandBucky prompt (I've waited two months for this I'm so excited) Post CW—Imagine a pining Bucky picking up on how Tony seems genuinely relaxed and comfortable (dare he say happy?) around Bucky, and being really, really excited about it... then noticing how Tony minutely flinches, shies away from, and is generally afraid of Steve. Which Steve notices of course, and feels terrible about it. Imagine Bucky trying to help fix things between them like they've both helped fix him.
Sometimes when things are broken all you can do is find a new way to be...though that's not necessarily a bad thing.
