(you're Flash's sibling, Batman adopted you and Flash, Flash has a torn suit, bloody nose and mouth, and fighting Reverse Flash, describe what you look like)
Flash: What did you do to the world!?
Reverse Flash: Oh Barry! That's the beauty of ALL of it. I didn't do ANY of it.
{Reverse Flash grabs Flash's head pulling it back, as Flash Groans}
Reverse Flash: You did!
{Reverse Flash lets him go}
Reverse Flash: Think Flash, THINK! Isn't there some little good thing, some little good deed, you might have done.
Flash: I saved HER....I saved MOM.
Reverse Flash: That's right!
Flash: NO! That wouldn't have changed what had happened before her murder! Bruce's parents! Clark's landing!
{Flash is on his hands and knees trying to get up}
Reverse Flash: You broke the time Barrier... Flash. Ripples of distortion radiated out through that point of impact. Shifting EVERYTHING just a tiny bit...but enough.
Flash: I just WANTED to SAVE HER...
Reverse Flash: Oh WAIT. You didn't stop JFK from getting assassinated. Or made sure HITLER stayed in art school. You saved your mommy. You MISSED her. And in a supreme act of selfishness
Reverse Flash kicks Flash in the back, kicking him back down as he grunts in pain as he talks}
Reverse Flash: Shattered history like a rank amateur.
{Reverse Flash stops kicking him}
Reverse Flash: Turned the world into a living HELL. Moments away from destruction, and I'm the villain?
{Reverse Flash looks at the destroyed world}
Reverse Flash: Good Job Barry. The world is about to end, thanks to you. I hope your mother has a good view of it.
Flash: You can't let this happen Thawne. You'll die too.
Reverse Flash: As you say in this era, totally worth it.
Flash: Unh!
{Flash uses superspeed to punch Thawne but Thawne uses it to step back}
Reverse Flash: As long as I can siphon off the Speed Force, you can't leave this timeline. I'm afraid there just isn't enough Speed Force to go around.
