Riku was gonna have to slow down with his explanations about this place, because they didn't really make sense, "My memories? The Organization messed with my memories?"

That probably explained the deja vu, but it wasn't enough to confirm that Riku was right. But Sora believed him anyway, because why would Riku lie to him about that?

"Well, whatever it is they're doing, we'll put a stop to it," If the Organization were still alive, then they were probably up to their same old schemes.
