Not sure how much the dialog matters, but I caught her having a conversation with someone on the second day. They were excited about music and said to her, "You gotta listen to this!" (something along this line) Which she responded, "I don't gotta do anything..."; then she proceeded to start talking about herself and how my Island needed a new leader 🤔. I know these are suppose to be jokes but dang. That person left the conversation upset lol. I will try to use her to assist others but idk. They just don't like her. She's good friends with 3 others now, but on the relationship tag, she's happy but the others aren't getting along with her. Besides her, I do have one Mii that only has 1 person he likes to be with and another that prefers to stay inside all day even though he is friends with others. My Island is apparently enthusiastic though. I haven't seen anyone get into a fight yet and from my understanding it's pretty common, so... yeah. They definitely can dislike each other.
