He's currently starring in the new V-WARS tv series, now in production. (It's a post-apocalyptic vampire show based the books and comics by Jonathan Maberry.) Don't know if that precludes him from guesting on DISCO or not.
The chance for an action figure with his bestie? I wouldn’t be surprised if they retcon Generations to have him be Robert.
‘Robert! I thought you died in the fire!’
‘No ducks, at the last minute Rene and I managed to beam out to Gascony! Isn’t it strange. Amnesia of course. Rene! Come say hello to your Uncle...He’s grown up a bit hitchhiking across France in a century with no cars....’
*in walks Seth McFarlane*
‘Hi Unc’ *aside* this is really gonna fuck with the The Orville vs DSC fans....dance number!’
