Quote #1
"I don't know you…" His voice croaked. "I don't know you… What do you want?" (1.37)
This is when Snow first meets Kelvin. He's freaked out because he thinks Kelvin is a visitor, and confused because if Kelvin is a visitor, then Snow should know him (because he would have come from inside Snow's head). It's not clear if Snow is more frightened because Kelvin is unfamiliar, or because he worries that Kelvin will be familiar.
Quote #2
As I did so, I had a premonition, amounting almost to a certainty, that there was someone inside. I went in. (2.2)
Kelvin's premonitions aren't especially reliable. Here he thinks there's someone in the room, but there isn't; it was just his own brain in there tricking him. Or… maybe he's sensing the psychic emanations of the alien ocean? Is he mistaking his own brain for an alien presence, or an alien presence for his own brain? Kelvin is a man of two minds.
Quote #3
A giant Negress was coming silently towards me with a smooth, rolling gait. (3.9)
This is the first visitor we see, and she's marked as "other" in numerous ways—she's black, she's a woman, she's dressed in non-Eurocentric style (topless and with a grass skirt). Alien-ness is presented in terms of race, gender, and culture. This could be a critique of the way sci-fi treats these issues, or it could just be a continuation of the way sci-fi treats these issues. Check out the "Symbolism" section for further discussion.
