(parody of the proverb 'Understand 10 things by listening to one')
Poor, poor Hina.
Hina curses helicopters, so Nagi decides to go by jet. Hina almost dies.
Hayate is still down. Maria wonders it's because of the night (the date with Hina)
Hayate says it is indeed, thinking that it's about the previous night.
Hina is shocked to hear this and she runs away from that place. And Hayate thinks that he has offended her again. So he talks to Maria about Athena(he didn't specify which girl he was talking about) and Maria takes it as Hina. She assumes that he's mistaking something. She tells him that if he is so worried, then he should talk to her about it carefully.
On the other hand, Ayumu cheers Hina up and Hina decides to confess her true feelings to Hayate in the evening.
My comments
This scene... I wonder what Maria is trying to say to Hayate in the last cut.
Maria: Hayate kun, why are you making melancholic faces since May?
Hayate: Eh?
Maria: You didn't make faces like that before.
Maria: Maybe, that... Hayate-kun... hey...
