If you’re up to it, I’d go talk to them at the next meeting. Meet it head on, mention what happened in the last org (at least with them removing you) and see how they react. Pretty easy to tell then if they’ve also grown as a person. If they haven’t, now you can use this to discuss more with longer time members and at least make them aware of this person’s previous behavior, lack of growth, and potential danger to the org
For some reason I thought this was 90 minutes but it’s actually 3 and a half hours
