"Chaos," he repeats to himself. His accent only comes out on individual words, and this is one of them. "And then?"

"Very well. It sounds to me as if you have a plan."

With this plan being relatively inconsequential, Hitan only offers an encouraging smile in response instead of, say, giving a more thorough analysis.
And anyway, even he wouldn't really do an analysis when it comes to this sort of topic.

He laughs a little. "I will be honest, Echo-san; I rarely pay attention to birdsong. Perhaps your friend has a better response?"

"Many?" He asks that but soon realizes that most people have more than one friend. Continuously speaking, anyways. 

"Oh, I meant to ask if you were planning on hosting an event and inviting others to it," he clarifies, conveniently leaving out how he doesn't attend those events due to, y'know, a variety of factors.

"Indeed," he agrees. 
Him not adding anything is probably meant to let her think, if she wants to do that.

Hitan looks at Silence as if expecting them to meow back. And no, he's not gonna do it. Good try though.

Yeah, he expected that.
For some reason, the feather next to Hitan's ear suddenly looks a lot more appealing to them now.
Oh, and he's more of a dog person. By the way.

Hitan, still looking directly at Silence due to the cat thing from a few moments before, continues his smile, almost as if he would discourage them from pouncing. 
Meanwhile, the feather somehow looks like it's moving, even though it's not at all, despite the wind. Yeah, definitely not helping matters. 

"Are you not able to fly already?" He's keeping his gaze on Silence even though he's speaking to Echo. 

Thankfully, a combination of many life-and-death experiences and Silence talking (a not-so-extreme combination, to be sure) means that Hitan doesn't fall for it. At least, not yet.
"Different skills come at different speeds to different individuals," he adds to what Silence is saying. "In addition, levitation is a subskill of flying. I would personally argue that it may in fact be easier to stay in motion compared to levitating. Oh, and stopping properly, of course."

He smiles at Silence, maybe seeking some sort of confirmation that they also understood what they said, maybe looking to see if they agree with his assessment. Yay, the narrator actually roleplaying Hitan somewhat accurately so that he's able to incorporate the maximum number of people into conversations like a good teacher would do.

Hitan keeps his gaze on Silence for a few more moments before ascertaining that they are probably not going to respond to what Echo said either.
"I am not sure, but truth be told, I would be more concerned regarding the mechanisms involved in stopping the levitation as well as any safeguards," he answers as he pulls out the beginning of something poofy-looking from a sleeve or somewhere. "For that reason, it may be worth more trouble than it is worth."
He lifts a hand up somewhat quickly, as if making a realization. "Ah. Have you worn Heelys before, Echo-san?"
Oh, and that hand's lifting up a cat toy, it seems.

(R.I.P. I forgot if he called her with an honorific or without lol, pretend that's changeable)

The toy is swishing downwards slowly, almost mockingly. At a halfway point, it whisks back up. 
"No," he answers, obviously not asking why she'd ask about shoes with a certain function if she doesn't wear shoes in general. "However, I have seen some children wear them. The design is intriguing, in my opinion."
