This reminds me of Milo. What do you people choose, deescalate the situation, punch or throw Milo or let Jeremy take care of it?
Chad Ian fights no matter what, he's always ready to rumble and having an opportunity for something other than Robert's face to catch hands is a welcome change of pace.
Normal Ian in a loving relationship with Holly, Lena, or Allison will talk Milo out of it. He knows he can handle Milo in a fight, and from this confidence, spawns the ability to be a better man and take the high road. Besides, Ian doesn't want to upset his girlfriend by getting into unnecessary fights.
Cuck Ian, or an Ian still hung up on Gillian is much more passive. He doesn't have the self confidence to use his wits or his athleticism to resolve the conflict. So Jeremy steps in to take care of the situation.
