Great call!! I was definitely thinking the same thing. I also believe the Jumin dude will be way worst putting Doc Dan in a more miserable environment/situation.
But I hope Dan doesn't go to the other side. I'd rather him just leave to somewhere far away or something prevent him from attending the fight. Preferably an emergency regarding his grandmother. Bless her heart. I do think there will be some kind of misunderstanding about Doc Dan. But I hope it's realized he's pretty loyal even to his own detriment tho. Just a prediction I could be wrong. ╮( ̄▽ ̄)╭

Even if we wanted to see him as a SL, it's basically impossible to happen. His character was created in the most exaggerated and stereotypical way possible, he's probably being paid by the rich people betting on the fights and his role is to "stole" Dan from Jaekyung. He'll probably be worse than Jaekyung and make Dan look even more pathetic since he'll be crawling back to the same jerk who mistreated him.
