"Enough to take out at least three levels of this building in one go if she's inside it," Tyler said. "According to her if we even attempt to remove it the thing'll explode. We need to defuse the thing."<br/><br/>"You can't," the woman said. "Damnit Tyler, the thing is wired up to my heartrate. The only way to guarantee the bomb can't explode is to kill me. Why can't you take the shot?"<br/><br/>"Cos you aren't who you say you are," Tyler replied. "You have a sibling here but its not Kayla. Tell her the truth."<br/><br/>"I'm sorry sis...Kayla," the woman said. "He's righ, I'm not your sister. Your parents adopted me after Mandy was killed in a bus accident I was involved in too. We looked so alike they hoped you wouldn't know. My real name is Kira Morrison. I wish I hadn't got to meet my big brother for the first time in years this way," she said as she saw Morrison approach. "Rick, I know this hurts but you have to ignore your emotions, you and I both know what'll happen if Tyler doesn't shoot. Linklater's done this before. Please." She could see the tears in Morrison's eyes, finding his sister again but being faced with losing her almost immediately.
