It was a longer trip than it otherwise would have been. Remus Lupin didn't use any of the shortcuts that the Marauders had set up or discovered, as his mind was on his mission. The Castle was subtly communicating with the wolf, and while Moony was surprised at this, there was enough intrigue for both Moony and Remus to want to know what the Castle was trying to tell them. It didn't take long, but had the shortcuts been taken there wouldn't have been enough time. Sirius had some of the spillover communication, and realized enough that he said nothing out lout. Neither he nor Remus realized that they had companions and frankly, didn't care.
