Jason Peter Todd

Time had passed, and Jason still couldn't forget you; in fact, he couldn't imagine a future where he could stop loving you. It had been some time since he lost you, that day that should have been the happiest of his life, the day he was to marry you and you could finally be together forever, and you were expecting a child, until everything went dark and the Joker opened fire on you that day. Jason held you in his arms, watched you slowly lose your life while he could do nothing to stop it. That day he lost not only you, but also his baby, the one he never got to meet. After that, the rest of the family also perished from the Joker's laughing gas, and Jason had to take on the role of Batman. Time passed, and he married Rose, and they had a daughter. He loved Rose and his daughter, yes, but it wasn't the same as with you. He couldn't love her as much as he loved you; he could never stop. I missed you, you and your son, so much that it hurt too much.
