After Minato Namikaze and Naruto were reunited as father and son in Obito's ocular technique dimension, even Guy was so overjoyed that he lost control of his emotions. He hugged them on the spot and burst into tears. Left with no choice, Minato Namikaze had to soothe him.
Once Guy had calmed down, Minato Namikaze and Naruto exchanged smiles. It seemed that all the words they had to say were contained within that warm smile.

"How is that possible?"
Everyone's eyes nearly popped out of their sockets.
"But, Uncle, isn't the moon in the sky?" Naruto had not seen Planetary Devastation, so he found it even harder to understand.
