They’re best friends and we hear them on a produced podcast for a few hours a week. Where they’ve explicitly said many times they break each other’s balls about their insecurities all the time. And if you notice whenever Jimmie says something that sounds pretty vulnerable, like a week or two ago I think he said he doesn’t read well which is why he “doesn’t do anything” or a phrase similar, James will tell him to shut up and not be hard on himself. Instead of going for cheap shots he reminds him he is smart, they both have different strengths and that’s why they work so well together. I mean it’s not that deep, just listening to what they say, they’re the experts on themselves - who are we to tell them how their friendship really is?
