Brian remembered the night of the attack, pulling Megan close and kissing her because he knew he might never come back. That moment he'd spent had possibly been the seconds of time that could have saved Betsy. Or maybe not. He'd never know. He had chosen to use the time that might have spared his sister to be with Megan. He felt a pang of guilt because he wanted to kiss her again and he knew he didn't deserve that.
