wild take but...
What if Jaegyeon just snuck Taesoo for fun lol. No betrayal. No traitors. Dude just fulfilled a grudge and then acted like he betrayed James just to get close to Jinrang and sneak him too💀. PTJ has faked us out before, so personally it could be possible? I've also had my own ideas on how Jaegyeon fits into the story which this betrayal has kind of ruined all of them so this might just be cope ngl. It's a fun twist for sure just not how I would have had the story go.
