Without TMI, I have drank a fuck load in a short period and your liver will literally hurt. It will stop most people (like me) from drinking but Cobes probably does the opposite and powers through to dull it. His liver probably is just wearing out from years of constant steady abuse. I know the human body can take a lot of shit (look at the homeless) but he seems to be sliding off quickly now.
I wonder how often Cobes has his freakouts off-camera? I know occasionally we see dents in the fridge, bumps on his forehead, or fucked up knuckles. I'm surprised no one who went to school with him has stumbled into our den of villany and told a few stories of him being fucking weird and disruptive in school.
