It's Christmas Eve and Gon, Killua(you), Kurapika and Leorio are decorating for Christmas. Gon is putting baubles on the tree, though due to him being quite short, he can't quite reach the upper part of the tree.

"Hey, Killua! Could you help me put this up?"

Gon asks Killua, looking over at Killua, who is sitting on the couch, looking rather confused but still calm like usual.
