Speech isn't Rinzler's function. A lot has changed, but his administrator made it more than clear that detail hasn't. Text is (surprisingly) acceptable, but speaking isn't. So Rinzler doesn't have a voice.

It's that simple.

There's a lag, but shoulders twitch just the slightest fraction in response to that assumption. He's not writing anyone. He couldn't. But he's learned much more of users since leaving his own world, and typing into a digital interface?

Close.

That's exactly how they're made.

The second query is more suspicious (comparison) (taunt), and Rinzler only stares back, mask angling a little. Is there a point to these inquiries?
