So like Mashin Chaser and Genm, Night Rogue's real identity is no real surprise, but I don't think that was the point. Bloodstalk is gonna be the real WTF reveal, because it makes too much sense that he'd be the cafe owner.

Now we know that Night Rogue's plan is to create a military force of Kamen Riders through human experimentation, and Bloodstalk is working with him. We also know that it was the cafe owner that urged Sento to become Kamen Rider Build. Now I'm sensing some double-crossing shenanigans between Stalk and Rogue in the future which may be how Sento managed to escape from Faust, or at the very least why he wasn't brought back to them. And we also know that Sento and Ryuga are the only specimens that didn't turn into SMASH, which likely explains why Sento is able to become Build and why Ryuga will be able to become Cross (because it's obvious that it's him).

And the cherry on top? Bloodstalk KNEW where Sento and Ryuga were headed. Okay, granted, "stalk" is literally in his name, so maybe he was able to track them down or something, but there's also the possibility that he was able to directly listen in on their plans, and it'd be pretty easy to do that if you were in the cafe with them.

I may be missing crucial details, but this is all adding up to me.
