I think this episode highlighted several things about some of the characters:
Spoiler:
Nagi even though spoilt, does care enough about Hayate to see past her own situation to his, hence wanting the 100 points for him.
Nagi understands Hayate, so is able to see his hesitation in the fight and spur him onto winning without hurting Hina.
Klaus is either a genius by being able to defeat all of Hayate's enemies or he is bleeping stupid
Hayate is faster then Hina, who is faster then Nonohara, so if Hayate concentrated on his speed he should be able to beat him (Hina did outsmart him by getting him to use his slow Safety Shutter).
Hina is a good loser.
