In between periodic requests, Gus has been focusing on a sketch of the scenery before him, so he's looking fixedly at the page when he's addressed by a man with an impressive voice.

"No, no," he says, smiling automatically, as he looks up. "I-"

He stops short, stalls out for several long seconds as he stares up at the shortish, blue creature standing expectantly before him. He notices, peripherally, several passersby glancing uncertainly, while most of the rest ignore them entirely, as is the wont of most lifelong New Yorkers.

Gus closes his mouth after a moment, forces the smile back out, and tilts his head in polite bewilderment. "I... am happy to do it," he says. "It's only a hobby." He flips to a new page, attempting very cautiously not to stare. Is this a costume? He's just not sure. It seems much too realistic for that - the way the light interacts with the creature's skin and eyes, the way its antennae move - but what's the alternative? For a moment he seems familiar, though Gus can't possibly place when they might have met. He certainly would have remembered, wouldn't he?

"Do you... have a request?" he asks, a bit dubious.
