The duel with Wulfgeat had a huge impact.
After Wulfgeat regained consciousness the next day, he returned to his territory, asking Reynold for a leave of absence. This shouldn't have been allowed because he was supposed to be Reynold's personal knight until he was 30 years old, but Reynold allowed it. His pride must have been shattered, especially since he was defeated so miserably in front of the crowd; the maids would see him with different eyes.
Likewise with Allen, the maids, who previously only saw him with a stern face, now greet him with a smile. They don't want to make enemies, not because they respect him but because they try to get close to him. Allen was a peasant just like them, so they thought that their lives might change a little if they could get close to him. Of course, Allen knew that. He was used to being paranoid about people, including the maids in Isabelle's house.
