Damn...there wasn't much in this chapter since most of the filler/pages was stereotypical responses. Probably the only surprising thing is Chelsea being able to accurately read Ryuusui. Either that or she's actually great at reading people and she purposefully plays dumb to break the ice on awkward situations (which has been a constant for her). So actually, with her being just as smart as Xeno and Senku, this probably fits the best.
Woah, Tsukasa isn't even shown in any of the panels with Stan being revived. So I guess this matches this chapter being mostly fluff. The panel of Sai being proud of Ryuusui's decision was another nice addition.
Stan shouldn't have cracks around his eyes since this is his second petrification...so he's "special" like Senku then? I forget what caused Senku to retain his markings from cracks, but this explains why the manga team introduced someone that made the powerhouses look helpless. At least this makes the "final war" much more interesting since they need someone this overpowering to overcome the twists why-man has.
