Percy would scream Thalos's name if his neck didn't feel like a deflating balloon. He settled for a smile under his gas mask and a thumbs up when he realized his father couldn't see his face.
Thalos was almost brought to tears from his rage, though. It's a strange thing how anger could do that to a person, but he was just glad Percy was safe.
He took something out of his pocket and knelt beside Percy. It was a glass vial with a clear blue liquid inside.
"Can you take this, Percy? Just drink, it'll heal your throat and other injuries."
Thalos helped him sit up and take off the gas mask, then he drank the blue potion and felt warmth spreading through his body. His throat, which he didn't know was so battered, popped and the bones cracked into place.
He took in a deep breath as his back cracked into place, too, filling his lungs with air after the long time he'd spent unknowingly deprived.
