Adrian
My name is Adrian and I am the fastest teenager alive. Probably . Until a few months ago, the year 2066, my life was normal. Well, speedster normal. I was running to pick up some big belly burger when a huge explosion of blue-ish white light came out of nowhere and transported me to god knows where.
Barry
My name is Barry Allen and I am the fastest man alive. When I was a child, my mother was murdered by the Reverse Flash. Yet, Nora Allen is standing in front of me with my father, who was also murdered by a speedster who hated my guts. So I went back in time, beat up one speedster, and saved 2 people. Well, probably more.
Barry went to his house to see his parents and tell them about his latest accomplishment of asking Iris West out. Though surprised, they were glad their son was making adult decisions. Barry hugged his parents and left to and abandoned warehouse with some food.
"There better be curly fries in there" said Thawne referring to the big belly burger that Barry was holding. "You know humans can go up to 3 weeks without food so I'd sound a little more grateful if I were you" Barry said to his arch nemesis/ prisoner. "So what should we call this brave new world that you've whipped up for us. I was thinking 'Flashpoint' "said Thawne like he was advertising a new product while waving his hands. Barry was about to leave when a portal opened and swallowed him which left Thawne speechless. Quick on his feet, Thawne mustered all his speed and vibrated out of the prison Barry made him and went back to the future.
Barry ended up in a place that looked like Central City, but a thousand years ago. Barry got a glimpse of blue and white lightning before he was thrown back into his own timeline, Flashpoint. When he got back, the Reverse Flash was nowhere to be found. Then a kid who was about 16 appeared out of the same portal that took Barry back in time. He said "Flash?" before he was sucked by the portal. Barry was in his normal clothes so he wondered how the kid knew his identity. Barry was about to go home and sleep when the Reverse Flash appeared and punched Barry in the face. When Barry woke up, he was on the other side of the speedster cage. Since Thawne knew the speed force much more than him, Barry took a shot and asked him what was happening. The Reverse Flash, who looked scared and angry at the same time shouted "You broke the speed force!"
