Barry Allen, one of the newer residents of the X-Mansion, was currently talking to Charles Xavier after learning something new about his powers. He had recently learned that he could somehow move at speeds faster than the speed of light and managed to even travel back in time slightly.

"So you're saying you went back in time?" Charles was certainly amazed to hear this.

Barry nodded in shock. "Yeah! I mean, I went back a whole day. It was like the weirdest case of déjà vu I've ever experienced."

Charles was shocked to hear this, but he also knew there would be dangers with this power. "So let's imagine that it is, in fact, possible for you to run faster than the speed of light and, in so doing, travel back in time," Charles said. "It still would be wildly irresponsible to ever do it again."

Barry sighed as he sat down on the steps to the school. "I knew you were gonna say that."

"Yes, because, Mr. Allen, you are a very smart man," Charles said. "Barry, if you were to go into the past, any interactions you have with your parents or yourself, stepping on the wrong blade of grass, you have no idea what the consequences to that could be!"

Barry nodded and understood where he was going. "No, I know--the Butterfly Effect, right?"

Charles nodded. "Yes, the butterfly effect."

Barry nodded as he understood the professor. "I do get it. But Professor... I can fix things."

Charles moved his chair forward so he was closer to the boy. "You can also destroy everything."

Barry thought about all the things he could do with these powers. "I could save her," he said, referring to his mother, who had been murdered when he was a boy just a few years ago. "I could save both of them." His father was killed when Darkseid appeared on earth. "I... I could warn people about Darkseid, and I could even save your legs."

That one seemed to strike Charles the hardest as he gazed down at his immobile legs. He would give anything to have the chance to take a stroll to somewhere again. "These scars we have make us who we are. We're not meant to go back and fix them. And there's nothing broken with you that needs to be fixed. Take it from an old guy who's made a lot of mistakes: Don't outlive your past. Live your life. And don't let your tragedy define you."

Barry sighed as he thought about his newfound powers and wondered what he could do with them. "What if it's supposed to define me?" he asked. "Your tragedy made you a hero."

Charles then thought about all the people he had in his life at one point. His adopted sister had left him, his brother was in a coma, and his best friend was now his mortal enemy. "It also made me alone," he said. He then moved his chair so that he would leave the boy to his thoughts. "Think about it, Mr. Allen."
