Tbh I read all of this today, and contrary to popular opinion, I didn't see too many things in this fight that hadn't been telegraphed in the writing somehow. I think the reason so many got that impression is because of the fact that this is an adaptation of a LN, so I assume the hints of later developments got more fleshed out there, while in the manga we would get a bunch of short blink-and-you-miss-it hints several chapters before
