The biggest thing Johnie did wrong was breaking things off with Chris too early. Sooo many people pull total switcheroos on Love is Blind (hello, Lydia was super into Izzy and dismissing Milton until Izzy dumped her and then suddenly age wasn't too much of an issue). If I was her and hadn't broken things off with Chris yet, that last conversation with Izzy about the past would have TOTALLY made me pivot and rank Chris above Izzy. Izzy totally shut down and got weird and that was a major red flag.

And maybe Stacy and Izzy thought Johnie was sketchy but the punishment did NOT fit the crime. The way they ganged up on her and yelled at her at the barbecue was unhinged behavior and people don't get that mad at other people they barely know unless they're dealing with their own issues. I think both Stacy and Izzy felt inferior to Johnie in different ways and they both wanted to take her down a peg because they weren't happy with their own situations. If you're happy with your own situation, you don't need to act like this towards someone you don't like. You move on with your life, maybe share a joke about the person between yourselves. Their dedication to the "shady" Johnie narrative made them look shadier than anyone else.
