It did seem like Zero Stars Grandma Chicken recorded his segment at another time, away from the HGs because you're right that they absolutely didn't react at all. You'd think if he was there, they would at least give some courtesy giggles or play along. Since the comp took place kind of late after the DE, it may be that they just got basic rules and he was edited in later. He was the only good part of the ep for me.
I am glad the CO achieved their mission. That being said, I think Kyland is annoying (and a big baby) X is incredibly narcissistic and DerF has misogynistic tendencies s
