In the Flash Season 1 we are introduced to the world of Barry Allen, forensic evidence analyzer for the Central City police department. After he lost his mother to a creature that he has never seen again and of which nobody believed and his dad went to prison for her murder, Barry started looking for the impossible. It only makes sense that he would be interested in evidence. We get to meet everyone in Barry's life. Det. Joe West and his daughter, Irish, with whom he lived after his family was rippd away from him. We will get to know the employees at STAR Labs who help Barry understand his new abilities: Harrison Wells (who was in charge of the accelerator and ended up in a wheelchair from the accident himself), Caitlin Snow and Cisco Ramon. Rumor has it that both Caitlin and Cisco will be recognized as metahumans with abilities of their own, too. Along the way Barry will discover if he has it in him to be a true hero. He will watch the girl he loves, Iris, date Det. Eddie Thwayne and we will get to see his world cross over into the Arrowverse. A whole lot of awesome is coming in The Flash Season 1.
Barry: I love you, Iris. Iris: Oh. I love you, too. Barry: When we were kids I loved you before I even know what the word love meant and then my mom died and I had to go live with the girl I had a crush on. Look. There were so many times I wanted to tell you; Jr. Prom, when I went away to college, when I came back from college, nights that we stayed up talking, all the birthdays, all the Christmases, but I, I never did. I kept it in. After I lost my mom and my dad, I was afraid that if you didn't feel the same way, I would lose you, too. That's the irony. I was so scared of losing you that I did. I know I've had our whole lives to tell you this and you're with Eddie now and I know that and I know my timing couldn't be any worse, but I just... I couldn't lie to you anymore. I'm sorry.
