He is later seen to be perfectly fine,with no sign of injury whatsoever.

When King asked Helbram whether if he still intending to kill humans,, Gustav and his comrades were shocked of their superior's true nature and as when the Cardinal ordered his subordinates to give all their powers to him, Gustav and the others tried to break their connection to Link, only to be taken control by Helbram's Blind Follow and gave all their powers to the mad fairy to battle the Grizzly's Sin of Sloth.
