I think a lot of people didnt understand how much Ralph banked on Jim's tacit support through all this shit hes been through. Jim really was his internet Daddy. Whenever he got into the shit with someone, even when he was 100% clearly the clown in the situation, he could always go, "Yea well, Jims been on this show exactly 28 times, which is 28 more times than youll ever ghet 'im."
I dont know why Jim waited for things to get so untenable before he pulled the cord, but there has been some seriously weird vibes under Jim x Ralph for a long time and now that Jim did the needful, I think we're gonna see something different. The coming week is going to be a picture of Ralph in a corner, mentally, with what he imagined as his most important social safety net yoinked from under him. And thats not even to speak of Gator and Dax.
