I don't know if Rob pretends to be, did the DUB or just pretends to be someone pretending to be. The thing about the RV, "Evidence," is that the evidence was so ridiculous that someone smart enough to write a coherent sentence, which Rob certainly is, has to know that the evidence presented was totally ridiculous...but then he goes on talking about it as if it wasn't.
IOW, Rob's MO...regardless of what is or is not actually true...is strictly just fucking around with people, at this point. Besides, he's funny.
Who gives a fuck what KewlJ does or doesn't show? I'll just assume everything that he says from this point forward is a lie and that's good enough for me. If he deems it necessary to prove otherwise, then he is free to do that, but I don't really give a fuck if he does or not.
