I think Than works for rockstar now as a game tester

Than left them. He was on jim and sam a few times after he left there just hanging about. Think he said he's working at another gaming company now but i stopped playing games around the time of Vice city so no idea if they are a big name or not.

Than left initially to be a stand up, I guess that didn’t work out.

Probably spoke back to Opie once and Opie cried to management to sabotage Erock.

Opie and Sam bullied Erock behind the scenes and forced him to eat junk food until he became the size of a house.

I think r/opienanthony might be more equipped to answer this
