It's Fine
Raven and the others are on their way to the eastern border. The reckless attacks from the western border made him suspicious.
They had just finished defeating the ones in the eastern border but even that fight made him uncomfortable, they were too easy to defeat.
As compared to the ones from the western border who were wrecking havoc, he can tell that something was not right. After feeling this way for a while, he took Hideyoshi, Azusa and Feena to go straight to the eastern border.
Today the rebels in the western border were doing their best to wreck havoc, it just so happens that today the princess will be visiting the eastern border.
All of them became complacent not even noticing these subtle hints.
Raven, who realized it, was already in the western border, by the time he arrived back to the kingdom. Eureka and the others have already left for an hour.
