User blog comment:Crazy sam10/No exos in BOIII confirmed/@comment-24260323-20150411170037

If Alex did survive to be a playable character in BOIII, then I think that he'd be still fighting all the way up to the end of BOII. But as the years go by, he gets older, his body can't handle combat and he could possibly become a cyborg if he remains as an active character.
