Forget the fact that he likely left a glob of slime on Herbert's nose with a lack of care as Tyki makes every attempt to rise to his feet without consideration that he might not be ready to get up right now. It's only when something is jabbing his back does he reflexively shiver at being touched somewhere sensitive and halt his rise upwards. He spent a good while in that slime with Joker before he dozed off and went under. It's completely cured with decent results.

The only real thing to note is the angry and thick scars that stretch down Tyki's back, around his side, and across his front. Following the pattern it looks as if he was once cleaved in half and while the damage is significant on both sides his front has the thicker portions.

"What kind of herb?" he asks as if all he heard was the word Herb in general. Sorry, he's just not paying that much attention which is likely why Herbert was getting away with touching Tyki at all. His wings are reacting as they raise with each touch to his back. Slowly, he's getting a little unnerved. Ginko had at least asked. Then again, Tyki had somewhat invited the unwanted touch.
