A hint. Narancia probably didn't know it was a hint -- maybe it was subconscious or maybe he was just being dumb. Fugo didn't care, either way. It was a chance to see his friend again.

He didn't bother walking, he took off running after Aerosmith in a full sprint. His legs and lungs could burn all they wanted; Fugo wouldn't stop until he found out where that plane was going. He didn't want to risk losing sight of it, either. It was a glimmer of hope he could see, one he could grasp at. It was tangible. It was all that mattered.
