I didn't see S1, so I didn't know about Jon until 2.5, and... I think he does? It's really hard to tell what he's serious about, and what he's playing up.
Like the full TJ negging thing I posted, he had to realize how gay it looked, right? He had to have known that watermelon isn't the same as water, surely. But right after that, he complains he hasn't eaten enough, and he hasn't had enough calories. Someone offers him a pack of noodles and he turns it down, saying it's poison. He argued with everyone, but he's adamant that the noodles are poisonous, that they have forever chemicals, and they're bad for him.
And jerking off is gay, and makes your T count lower, but a woman jerking you off makes your T count go up.
I can't tell the act from the actor.
