Damian's POV

Entry 122 Year: 2151

I have been immortal for 122 years. Unfortunately, due to my actions, my world is now is ruins. Families are destroyed. Blood tainted the buildings and streets. It was all my fault. If only I didn't kill him. If I loved him. If only he was my...father. I know now I must go back in time. To change wrong to right. I have already a plan how to do it. To help me, I've recruited an old friend to help me. Bart Allen, the fastest kid in the world but not exactly a genius. NO P.O.V For days,weeks,months the two created and work on the invention of century; a time machine. It would take them to the year 2013 where they can change the timeline, for the greater good of humanity. Finally, it was done. " Now Wayne, understand that if we-" What do you mean by 'we' Allen", Damian interrupted Bart. "You don't expect me not want to go. That's when my great,great,great,great,great,great,great,great,great grandfather and 1st cousin(once removed) were alive, in their prime, and were they the Flash and Kid Flash. Please, please let come with you, please?" Bart said pleading. " Alright, in no may you alter the time line", Damian said. "Ok , like I was saying if something were to go wrong you may erase from existence permanently." Bart worryingly said. "I am willing to take that risk. For my Father, for m-our world" Damian said without a doubt in his mind. "So where exactly are we going?" Bart asked. "Not where but when" Little did they know of the sadness and anger that they would unleash , and cause the ultimate, tragic, sacrifice known to man.
