There is a not-even-five-foot-tall cat alien wandering around Los Angeles too. What a coincidence. Ratchet tries not to look too surprised when he's suddenly accosted and question ed seemingly at complete random. He stumbles over the question before hastily answering, more confused than anything else. "Newton- what kind of name is...uh...no. No, sorry, I don't."

He doesn't recognise the species of the person - which isn't that much of a surprise; he doesn't recognise any of the species on this planet - but more importantly, she looks completely different from any of the others he's seen. It might be worth finding out before she wanders off.

"Hey,you look like you're....not from around," he realises as soon as it's out of his mouth how offensive that sounds. "...here."
