In "The White Queen", Dolf taunts Alfred at the end that he can't prove that he tried to steal the Queen's crown, since they're just in one of Alfred's dreams, which he figured out the moment Alfred stepped into the bar that Dolf and his friends were hanging out in. If it's just a dream, and Dolf knew this why would he try to steal an imaginary crown that wouldn't be worth anything?
If it's a dream, then this is in Alfred's subconscious. And so we must conclude that Alfred already knows deep down that Dolf is a villain. The dream Dolf is just telling Alfred what he already knows, while throwing him for a loop by telling him it's a dream, because Alfred is himself confused about what is reality.
