Gyre's smirk, the hum, the shrug... it's all a lot less guarded than Garrot expected. Of course, he expected snarling and bared teeth and angry rejection, so... the bar's low. But the Monkey Knight finds himself nodding along, as automatically as if a colleague had explained a case looking for advice. It's nothing he can't handle, but-

Laughter.

Gyre laughed! Frankly, even before he knew about the decapitation, Garrot figured that Gyre just didn't laugh to save his easily irritated throat... and also because he's kind of grumpy sometimes. So to see his friend actually laugh and make a joke causes the last of his anxiety to utterly evaporate. And Garrot starts to laugh too, admittedly a bit longer and louder than Gyre's just because of who the bugbear is as a person. But he catches himself, containing his mirth so he doesn't attract attention.

"I mean, we can try it out once we save the world, if you want." Garrot, as a trauma surgeon, is mostly unfazed. In fact, he even seems serious about the suggestion, laughter notwithstanding. "You know I'll take real good care of you." So of course, he pivots right from serious offers of dismemberment to flirting. Because of who he is as a person.
