Legacy (The Flash)

"Hi, Mom and Dad. If you're watching this, it means that something went wrong. But I don't want you guys to be sad. I'm not. I always wanted to be a hero, to use my extraordinary abilities to help people. That's why I came here: to meet my family, stop Cicada, help fix The Flash's legacy, and save him from disappearing in the future. I believed I could do the impossible, but I never imagined it would turn out like this. I'm glad it did. I wouldn't change anything about my time with you, my sweet parents, the most important people to me in the world. I wish I could be there to celebrate every new chapter, to witness every success. Just know... that no matter where I go in my life, you'll always be by my side. Because of you, I know I will never, ever, truly be alone, and I will feel your love and support like a warm hug comforting me, wishing me to be the best person I can be. Thank you for everything... for making me a hero and for loving me even if I wasn't perfect. Please remember that I love you both, and I always will, no matter what the future brings."
