During the night that Eckhard had obliterated the Bavarian army tasked with assaulting the Northeast border, Berengar had gotten quite intoxicated conversing with Duke Otto and Liutbert, so much so that Adela was currently scowling at her father, blaming him for Berengar's current state.
"Father, why are you such a poor influence on Berengar! He should not be drinking so much!"
Berengar was entertained by the fact that he was not scolded for his actions, but his future wife had laid the blame entirely on her father. It just showed that Count Otto must have had a habit of overdrinking.
As for Liutbert, he was also being given the scornful look of a displeased young woman by his younger sister. She knew that Berengar was expecting an important guest to arrive, possibly within the next day. Thus, she was displeased by Berengar's actions; however, she held her brother responsible considering he too had drinking problems.
