If I read that part correctly (now that I've finished the game, I can be spoilerific now), he will die unless there are other strong characters that are loyal. It seems that I chose my peeps wisely; loyal Legion for the pipes (though I considered sending Tali), loyal Tali as escort, loyal Asari-what's-her-name as a guide, Garrus as leader for the other group, etc.
