I'm not much into making analyses this early, with so little to go on, and it's pretty difficult to find any suspicious things with you.
Anyway, I'm slightly wary about
Ka's approach on Day 0. She didn't speak only a little, and mostly sense, but about rather irrelevant matters like the game dynamics. It would have been, and still would be, nice to hear a little more what she thinks about people.
And with
Shasta there's absolutely nothing to go on.
There's this song by Current 93, named Twilight Twilight Nihil Nihil, and it seems to fit this day perfectly.
