Spoke to Zexi about the matter and warned him about keeping a professional attitude with the members. However I do recommend that you also try not to push any of the trials' buttons, they're learning and adjusting to their roles. We don't know what happened before your recording started so we can't say if you did or didn't push his buttons, I'm just saying for future reference. If any other incidents between the two of you occur again feel free to report him.
