Naruto simply stuffed some food in his mouth before turning around and facing the Uchiha. Watching him with a bit of an puzzled expression as he suddenly smiled. Really, what was so amusing? Naruto glanced around for a moment and didn't spot anything that would warrant a smile.

When Itachi spoke the Jinchuuriki snapped his gaze back to him. So he was remembering a smile but couldn't remember whose it was, huh? ...Wait.
"You're remembering stuff!?" he beamed at the Uchiha.
