Can't see videos, what's happened, josh and robc fallout?
No one knows, but I'll put together a work of fiction for you that will seem plausible.
Josh wanted to go to Vegas to collect some poker debts and asked Rob if he'd be interested in coming along as hired muscle/goon/intimidation factor. Rob initially jumped at the chance as he's all about that kinda stuff.
Josh also had some beef with Bhanky that he wanted to sort it out in Vegas. Josh threatened to shoot Bhanks and his scarecrow wife. Since then Rob has mostly been MIA. Most likely unrelated to this threat, but you can understand if it was and he wanted to distance himself from it. Josh said it was all talk anyway and Rob made some fleeting appearances again. On Robs reappearance Bhanky started to send some dating proposals in Robs direction, Rob seemed receptive and then went MIA again
Now Josh feels Rob is ghosting him on the original deal and wonders if Josh is all talk and is probably feeling betrayed by Rob accepting Bhankys date offer.
This could be a pretty good sitcom.
