just to be clear toobs, I don't think he would kick some trolls ass, I just like the idea of it. he's got like zero reflexes anymore though, that being said I think a lot of these reddit faggots that seethe over him probably do it because they see some of themselves in him. I think he'd probably have a fairer chance than you'd expect. I'm sure they probably also too get their asses kicked by can openers and fast food bags. I just inherently think one of the funniest possible routes for Josh's life to go is to end up like those delinquent stereotypes in anime like the beginning of Yu Yu Hakusho where for whatever reason characters just walk around town and get into street fights all the time like it's a normal everyday occurrence. Cobes vs reddit alogs in physical battles in the streets of casper wyoming would just be hilarious. plus you can imagine if he won a fight how insane his confidence would skyrocket and that would also lead to funny shit.
in all honesty he's probably too far gone and the booze, duster, isolation and lack of movement will probably take him out before he could ever have the chance for a redemption arc of any kind, let alone a hypothetical troll slayer one.
