Ando had been happy to have his friend there on the island, even if it was a future version of his friend that had lost him 5 years in the past. It didn't matter to him because having Hiro around meant everything would be okay. Except that now, everything wasn't.
Hiro was gone. Peter Petrelli was gone. And many other people, from what he could tell. He didn't know what he was going to do if he had to stay on the island without any version of Hiro. He would never admit it out loud, but he needed his best friend. So he decided to take a walk along the beach, trying to clear his head.
He wasn't really paying attention to where he was walking. He was just looking down at the sand, hands shoved into his pockets, trying to figure out what Hiro would do in that situation. He hated that he hadn't paid more attention to his best friend's comic books. They would have the answer.
Ando managed to look up in just enough time to keep from running into the man sitting on the beach. He gave him a quick bow.
