Or it's more likely that they haven't been writing him lines in because the voice actor is busy just like they mentioned in the season 6 commentary. They've done that several times, where they've "killed" him off or had someone like Miles do his lines. Turns out he has a ton of kids so he has his own priorities. It's not impossible that they've substituted but I sort of doubt it. Just hope they don't go the PTSD route like they were going for with Lopez.
