I agree with the sentiment most people here have that this will just be a dogpile on top of Jim where he gets one or two swipes in and it just devolves into screaming and kicking the guy, But I am more curious about the long term effects.
Assuming Nick actually talks to Jim 1-on-1 style, I expect him to be laughed at hardcore, I have little doubt that Nick has a whole lot he could try and hit Jim with that wouldn't either be A. a repeat of something Ralph said or B. uninformed/hypocritical/hollow bullshit. I unironically believe that this is the best case scenario at this point. He will look like an idiot, be mocked relentlessly and have clips be used against him by other commentators on the opposite side of the spectrum. He will hopefully remember it as a loss and will either brush it off or somehow learn something from it. (Whatever that something is, its up in the air)
If Nick just dogpiles Jim, He will not only of lost, but will have made up a win in the mind of him and every hollow-headed Groyper follower he has. If he wasn't going to be taken seriously before, god help him if he thinks anyone will take him seriously after. His best bet is to just listen and try to see past the fog of his own ego.
