Panic set in as Wayne scanned the crowd. This was what he'd been dreading since they'd left--they were separated now, and easy to pick off. He couldn't see anyone suspicious, or remotely out of the ordinary. Wherever Christopher was, it most likely wasn't in the station.
He wanted to believe that maybe Christopher had made it onto a train, or into the gents' toilets, or somewhere safe. Megan's agitated state meant the chances of that were next to zero. He couldn't Apparate. He couldn't run in this station without knocking down a score of people.
Worst of all, the woman on the tannoy was announcing that their train south was boarding.
"Come on," he said, grabbing for Megan's wrist to pull her through the crowd. "We need to find Eloise as well... The train's going to leave."
