Hmm, you might be onto something. That would be pretty disappointing, but maybe that would be more balanced. The ability basically gives Argalad the option to battle quest with him and the ability to commit him to the quest after staging. That's nothing to sneeze at. Damage to him would prevent him from getting out of hand.
But if that is his ability, he might go straight in the bike spokes. Although it also depends on his stats. So much speculation...
