I don't know, if I can talk about spoilers, so to be safe...
The face of Dr. Xeno was so filled with hope, surprisingly honest-like. We know, Dr. Xeno had always different goals than Senku, so murdering Senku was probably the logic choice in his greater plans (Tsukasa-ish a bit?), but I would never thought Dr. Xeno, who nearly didn't even blink before writing off Senku, was still so relieved when he didn't manage doing so. It looks that Xeno is soo not honest with himslelf, converting "dense" genious is gonna be a very hard work... Will see, if the story will develop this way, there will be complications, that's for sure, but it's there... or rather I believe it is
It's a bit hard to count, who is on the ship with Senku, I had to re-read the chap to be sure, so fast paced XD
I'm starting to like Nikki more and more, such a strong willed woman, kinda reminds me of Taiju in girl clothing But I think she might hide much more potential in leading ppl
