Spangles will adore Bucky, duhh! But Bucky also finds Spangles surprisingly endearing, even a bit comforting tbh, shockingly good wooby for a man with ptsd. Makes an excellent excuse to get out of a social scene -when Julie’s sore feet or tits don’t fit the bill, well, then they have to go feed Spangles. Never fails.
Also- Spangles loves to nap with Bucky and will hop up to join him on the couch or bed (hmm or maybe some cute little blonde helps him up) but either way, Bucky often wakes to a bunny laying across his face, nearly committing unintentional patricide
