I don’t know much about your characters as I haven’t been on here for too long. Thus, I’m only going off of what I do know as well as educated guesses.
Bacon would love everyone unless they were mean to him or Kathryne. Specifically, I think they’d hit it off with Runie as some people consider Bacon a freak of nature and they’re simultaneously made fun of and respected for it. This is due to their unnaturally high weight that makes no sense for their size. Even Runie might struggle to lift them. So they’d likely bond over that..
Kathryne would likely be distant at first but she might eventually come around to the group.. She especially has trouble dealing with extroverts so the more aggressively they approach her, the high the wall she puts up. Also, if she’s only starting to get along with one of them and they try to introduce her to the rest of the group, she’d shrink back into her shell in a heartbeat. It’s possible for them to be friends, it’d just take a lot of work.
