OK, definitely deliberately avoiding answering questions about who they are or what they're doing here. Interesting. Also sort of suspicious. But they're so nice.
She wonders whether serial killers are nicer than other people. No, that doesn't make any sense, if you were a serial killer you wouldn't be wandering around in the middle of the Arctic wilderness where there aren't any people. At least, you probably wouldn't be. No, if you were a serial killer, you might be nice, but mostly you'd be normal, because you'd want to deflect suspicion. And they're being super suspicious. So suspicious that they probably can't be serious criminals, because a serious criminal of any sort would be taking more care not to act suspicious. As a serious criminal, she feels like she has a certain degree of expertise in this area. So if anyone would know, it would probably be her.
Yes, sensible. She nods.
"OK! Anyway, I have to get back to delivering stuff. I did promise the guys at the research station. I should be back, like, really late tonight? You guys can hang out here as long as Kor's here. If he wants to take Zada back to his house, then....?"
