I'm with you. Nettie would have been great ad a companion. And Barcus feels just primed to be one as well. He's got his own journey that he's on, but you can befriend him, it writes itself. The only question is what class he would be. I don't think anything really fits him. Not even artificer if that were in the game. Not everyone who tinkers and can build things is an artificer.
