This takes place in Pete's World immediately before the first chapter in An Unexpected Family.
Jackie Tyler leaned over her son's bed. "Goodnight, my Tony," she said as she gently pressed a kiss on to his forehead. He murmured a sleepy, "Love you," and succumbed to sleep. Something felt different about leaving him now. She'd tried to shake off that feeling of foreboding but it wouldn't budge.
It was getting late and they had somewhere to be, so Jackie headed downstairs and out to the limo. Pete was standing outside waiting for her. "We're going to be late," he chastised without any real mirth.
"Yeah, and you can button it," she smiled. "I wasn't leaving until I tucked in my little man, plus the man of honor is never late."
"Everyone else is early," Pete laughed and he leaned down to kiss her. The sound of a car door banging open and running heels on pavement caused them both to look up. Rose was running full sprint for the house and the Doctor was climbing out of the car.
"Sorry, sorry," he said as he tripped over his own feet. "Apparently, morning sickness isn't just for the morning. If we're not back in five minutes, just leave without us and we'll catch you up." And in a flash he was gone.
"I would be annoyed," Jackie said, slipping inside the limo, "if her running off didn't mean I was about to be a Gran."
Pete settled himself in next to her. "It is wonderful news. Life is pretty good right now." Leaning over, he kissed her cheek.
Two minutes thirty seconds after Rose and the Doctor had headed back towards the house, Jackie gasped as memories flooded her mind. "Tony," she whispered.
"What about him?" Pete asked.
Jackie gave a sad smile. "He's going to be amazing, they all are." She gripped her husband's hand tightly and a moment later, they were no more.
