The ice cold feeling striking Murderbot's nervous system is entirely based in neurochemicals. Someone who speaks so casually of humans as the aliens. Perhaps coexisting but distinctly not what this biological person is. It's not overreacting due to villainous portrayal on the entertainment feed. Humanity that it is familiar with has never met the aliens whose remnants humanity stumbles across to dangerous and deadly results. It has experienced that contamination. It nearly died. It would have been forced to kill or subjugate everyone else unless its people killed it (low odds, no matter the situation).

Perhaps the freezing itself is alien contamination.

Threat assessment still assesses the alien as a low risk of threat, despite the organic based response. It helps that being frozen doesn't let its system get overloaded. Perhaps that does it. Alien remnants usually don't have intent. They simply are unhealthy to interact with.

"We have science and technology," Murderbot says, "Magic is only in stories."

It sighs, "Most people don't like me." It would shrug, but those opinions don't matter. Not really. Not much. Halfway convincing at best, even to itself.
