I've been rewatching Dr Stone for the final season and tbh it's better than I remembered but I do have 1 gripe; Tsukasa is regularly able to pick up on Senku and the science kingdom's plans super fast in a way that seems implausible. It makes it feel like he's working with the same type of science knowledge that Senku or Chrome have but we really don't get much information to substantiate why the human gorilla/strongest teenager knows all of this.
For example, when Chrome is imprisoned Tsukasa deduces that the way Senku will try to save him is with a steam powered machine. But how is that his first guess? After all of Senku's advances he has multiple options open for him (stealth mission, full assault, possible air attack) and I'm not sure how Tsukasa knows he's this far ahead without his spies. The only way I could see it explained is that when Tsukasa lived with Denji he learned his patterns but even then he's working on telepathy level reading.
