My mom was killed by my archenemy from the future. He thought he could come to the past to kill her and prevent me from becoming the Flash, but it turned out badly for him. By me not becoming the Flash, he lost his connection to the Speed Force which gives us both of our powers. So he impersonated a scientist and triggered the conditions to turn me into the Flash, then tutored me for almost a year. I had no idea he was the man who had killed my mother, and he'd become almost like a father to me. I know our stories are different, but I understand where you're coming from. And if you ever need anything, I'll drop everything to come and help you.
