Scenario:Reverse Flash while captured explains Flashpoint to Flash. Franchise: DC Universe
FLASH: What's happening to me?
REVERSE FLASH: I was wondering when you'd notice.
FLASH: It's like I'll be thinking of a moment from my past and then it... It vanishes. I can't get it back. Why?
REVERSE FLASH: Flashpoint. It's a side effect. See, I told you before. You don't know what you're doing. This new reality you've created is starting to overwrite the reality that you and I know. So your original life... Your friends, your family... Pretty soon, all of that will just fade away.
FLASH: Why isn't it happening to you?
REVERSE FLASH: Not sure. Unless...
FLASH: What? What?
REVERSE FLASH: [Laughing]
FLASH: What the hell's so funny?
REVERSE FLASH: Your speed! [laughing] The more you use it, the faster you lose your memories.
FLASH: No. No, you're lying. You just want me to let you out of here. That's never gonna happen.
REVERSE FLASH: The you I know from the future, he's not this stupid. Pretty soon, you won't even remember that you're The Flash. And when that happens, this world will become permanent. Time will set like concrete, and nothing will be able to change it back to the way it was.
FLASH: That's fine by me.
REVERSE FLASH: You know what you have to do. You have to take me back to that night and let me finish what I started.
FLASH: You go to hell!
REVERSE FLASH: You're taking both of us there! Now who's the villain, Flash? Now who's the villain?
