If those existed in his universe, Constantine would probably never have stopped smoking. Even more so than he already did, or did not. Balthazar just barely flinches — it's not as bad as a face full of holy water, which he considers refreshing anyway — because it's so unexpected, both the holiness and the fact Hellboy is smoking them. He delicately leans away, which could be construed as general aversion to smoke. If it gets in his squishy demon lungs, he'll be hacking for at least a day.

But all that is less distracting than the name. What. Though he fights not to show it, exasperation creeps through.

"What? Like a superhero?"

Only then is when it hits him: that's totally what this guy is. Name is Hellboy, appears to have been engaging in heroics rather than depravities, smoking holy tobacco, wearing a trenchcoat that feels like it's got charms inside — this Hellboy is totally a superhero. His left eye actually twitches a little.
