It wasn't the thought of Harry's reaction that scared her the most. That was one factor of course. It was the fact she had something growing inside her, a new life...a baby. That baby would be born and would grow up calling her 'Mum'. She'd be there to love it, teach it and protect it from the world; but she couldn't do it. It scared her so much that every night she tossed and turned uncomfortably in her sleep, having dreams that soon turned into nightmares of what her life would be like. She couldn't seek comfort from Harry, the comfort she so very much desired, because she hadn't even told him yet; the right time had not yet come. Or what she felt was the right time. She'd had many opportunities but she'd chickened out, she'd become a coward. She knew he'd be as scared as she is, be frightened at the prospect of becoming a father. He'd told her many stories about his past, his parents and his upbringing, and she'd told him hers. He'd mention about his fears of turning into his own father, becoming aggressive and a let-down. He didn't want that; he didn't want to leave like his father did, deny his child their right to have a loving role-model to look up to. But he felt he would. He felt he'd gradually become him and not be able to reverse the change. They were both scared, scared of themselves but they just had to admit it to each other. They just had to open up about their fears to be able to move on, to accept what was going to happen.
And finally they did.
