[She frowns, cringing at the sight of the mushy mounds of wet, gross, chewed up cake on the plate.]

Ew! Why are you wasting such a good cake, Oniichan? If you don't like it, I can still eat both of them!

[When Killua brings up the cake's taste only being good on her plate, she pauses eating.]

Huh? I mean...maybe the room just likes me better? I dunno...but I'm not letting you steal my cake and spit it out on my plate again! You want some, and I'll share it with you. Okay?
