When Vaan left the underground training chamber, the guards immediately informed him of their family head's desire to see him. As such, he willingly followed them with a look of ignorance, seemingly unaware of what was happening.

Evron family's estate, Meeting Hall

"What? Quickly send him in at once!"
"Yes, my Lord."
News of Vaan's arrival quickly reached Beru's ears before he urged his servants to bring Vaan inside the Meeting Hall to see him. Besides Vaan's absence, all direct members of the Evron family were present.
However, everyone's eyes were red, weary, and filled with concerns and worries. It was clear they had stayed up all night.
