Regulus had run off to find his friends, and Sirius had parted company with them as soon as they had reached the station. Of course, it wasn't surprising anymore, not considering the summer they had had, and it was the reason that his wife had decided to stay at home rather than see her sons off on the platform. It hadn't been all that many years ago when she had come her so proudly, proud of them, and seen them off to school with a tear in her eye. Or perhaps he was remembering it more sentimentally, but there was no doubt things had been better then, much better.
He sighed. Abraxas didn't seem to be about, and the tall blonde man normally towered over most. Cygnus wasn't anywhere in view, although his three would be old enough now to escort themselves onto the train, and if any of them were like his own, they no longer wanted to hold their parent's hands and be babied. Now the boys were older, they needed a different sort of helping hand, especially Sirius who seemed to take so much pleasure in making life so much harder for everyone else...
But that was the way of children. Wayward and in great need of helping hands, even if those hands were invisible, stirring them, shaping them into the adults they would need to grow into. That was why he'd come here, to ensure that Sirius' path took the right fork. Although with the platform this busy, it was impossible to keep an eye on exactly what either boy was doing.
