So… Where is he?

You're walking the floor at a PTQ when you notice a table with only one player. You glance at the clock and see that just over 10 minutes have elapsed, so you step in, pick up the match slip, and ask the player across from you “Are you Anton or Nikolai?” He replies “Oh, Nikolai's here. We've played game one already. He saw I was going to sideboard and I think he went to get a soda.” What do you do? Judges, feel free to discuss this scenario on Judge Apps!
