After dining with his in-laws, Berengar took a bath before entering the room he was provided. It was down the hall from Adela's and Ava's. However, he had no intention to visit either of them in the night. Adela was too young for his interest, and Ava, well, he did not desire her, though he was wary that the woman might pull something in his sleep; as such, he made sure to latch the doors and windows to his room thoroughly.
One could never be too careful. If Berengar were in the modern era, he would probably search his room for bugs before resting, but this was the medieval world; such sophisticated technology did not exist at this time. As such, he was able to sleep the night away without concern.
By the time Dawn rose, Berengar had naturally awakened, after all his body was used to waking up at such an hour; despite this, he was left with nothing to do as he had no major work concerns while he was in Graz, and most of his exercise equipment was at home.
