Rawdon had mixed feelings about heading back to the station. He knew that he couldn't really stay in this world - it was his own past, and from what he could understand, his own past self was out there somewhere just waiting to be bumped into. At the same time, there was that desire to just bend reality. To have that second chance be a little more literal. Never marry Becky make things right with his father, selfishly pull Shepard into his own world for a while longer.
They'd fallen kind of quiet, both apparently lost in their own similar but different thoughts, and he was just watching the world slide past the window as they continued on their way North. He took a sharp breath, snapped back into the reality of the moment by the sudden question. He gave her a sort of gruff sound of confirmation, and then leaned to knock on the glass to get the attention of the footman.
