"I wouldn't worry too much about that," Strange teases, as that frown turns to a small smile. "Madness would probably play out a little bit different than weird memories--it's when you hallucinate that you get shipped off somewhere."

His tone is a hundred percent teasing, Strange trying to deliberately keep things light and jokey. However, there's an odd matter-of-fact tone to his voice. Of course madness doesn't involve fake memories, going crazy would be entirely different than that! Just...don't ask him how he knows that (because honestly, Strange has no idea how he knows that in the first place.)
