The cricket chirps again.
Kiaan makes a "mmmm" sound after about 2 seconds.

The cricket does not chirp further.
Kiaane decides not to address Martin yet, instead regarding the cricket--or rather Martin's sleeve, since it is still hiding from the mage's presumable but nonexistent wrath. They presumably are questioning what "mmmmmmm" means in this context, but the cricket is just not responding. 

Kiaan holds out their left hand almost tentatively. 

The cricket is staying in that pocket for dear life. Uh, that's a dramatic saying.

Kiaane agrees, but you wouldn't be able to tell that by looking at them.
The cricket is gloating in Cricket, though it's not doing that "vocally".

Trust me, the cricket's comfortable enough as it is. It probably doesn't even deserve to be so comfortable, in a sense, to be honest.
Does it look like Kiaane has any friends at all? His sole friend is basically someone in his adapted family right now. So, he shakes his head.

They can talk to humans; why don't they have human friends?
Kiaane ponders that for a bit. "I don't go outside," they finally conclude. Like that's a viable reason, pfft.
...or maybe it is. The narrator doesn't really have many human friends either. Lol.

It's unknown how Kiaan thinks about that magic potential implication thing, but whatever they feel, they certainly don't show it on their face.
The cricket just kind of...chirps. 
Kiaan just kind of nods right after that. "Cricket?" they ask. 

It did answer. For the sake of how they communicate, Kiaane nodded instead of saying something affirmative aloud. 
Looks like Martin will have to get used to how they express stuff.

Kiaan stares passively, not getting social cues, as per usual. 

No idea, to be honest. After a while, Kiaan's probably going to seem to forget about the conversation in the first place and then just turn back to the books. Despite what they look like, they are a nerd by definition. 
Has he?

"Lunch?" Kiaane's first response is just to look for the sun to check the time. There is no sun in this place, so there goes that.
The cricket chirps, like it's laughing at the older mage.

Kiaan looks Martin dead in the eyes. It's actually not that dramatic. "You are hungry?" they ask slowly.

Kiaan, who ignores hunger to the point of probably forgetting it, is actually confused. They're not showing it outwardly, though.
"I think we must leave, then," they say.
The cricket chirps, wanting the apple.

The cricket chirps again.
Kiaan's kinda just looking at Beauty and the Beast, as if unsure if they should leave it here or carry it with them.
