The Panda family and Kuys had more or less expected this thing to happen.
When Ban reported what they saw earlier that day, Kuys was already aware that the Dark Guild had some involvement regarding this premature Beast Tide.
After the encounter earlier with the group of scouts sent by the auction house, or rather, the Marchand's, Kuys predicted that the Dark Guild would move drastically and might hasten their real motives.
And indeed, Kuys managed to guess correctly.
Just a few hours after the encounter, the bell of danger has already chimed in panic. Even without anyone reporting him, Kuys was already aware that it must be the Beast Tide's situation that had experienced a drastic change.
As the chimes of the warning bell gradually grew weaker, the people of Eagle City gradually grew into panic as well.
