Eyup. However until I see proof in the show that he's alive, he's dead. Its like saying Bobba Fett is still alive in the Star Wars universe after Empire Strikes Back. No, he's dead, and will be dead till he shows up in the series. They granted that part of the RvB lore some closure following into Season 10, and 11. Honestly, they DON'T, need to bring him back. No reason to.
