In an attempt to free Misao, Sammy says these words to her: "Even if you stay as Pixy Misa, forever, I'll still really be your friend, Misao!" Aww.
Besides that, there's also Sammy and Misao exchanging words:
Misao: I... I... I want to be your friend!
Sammy': We are friends! Of course.
Misao: I want to be with you!
Sammy: I'll always be with you, Misao!
Misao: I care so much for you!
Sammy: I care about you, too, Misao!
Misao's reunion with her estranged father.

Rumiya getting pushed into kissing Misao. Rumiya was a very cute and likeable Chew Toy throughout the entire film, and Misao was an adorable unwilling pawn of evil. Seeing the two of them hook up into such a sweet Toy Ship like that just gets me every time.
