For that case... Hm. My memory's vague but I'm pretty sure we get some pretty overt flashes to his true identity and intention here and there even if he doesn't go full Sidious until towards the end of the series. Of course, I don't imagine they would try to hide anything; the fact that Palpatine is Sidious is a pretty obvious fact to anyone who watches Episode III. It's a spoiler I doubt the creators would do much to hide.
