TK and Rachel at the Hole Building. Finally, he figures out that they need to go inside and up to the observatory, but she's unconvinced. Having seen the hours of operation on the sign (and for those who were suspicious of the handwritten sign on the door, note that you can see a more substantial, permanent sign here as they pass), TK tells her on the way up in the elevator that they're clearly not as far behind as it seemed like they might be. She remains nervous that the clue didn't say to go to any observatory.
Ron and Chris are the first team to get to the Osaka airport. They hustle inside, where they spot a flight to Taipei on the Arr/Dep board that leaves at 1 PM. Nate and Jen and Nick and Don aren't far behind.
TK and Rachel get as close to arguing as they ever do, which is to say not very close, as she continues fretting in the elevator that the clue didn't say to go to an observatory and he insists that he really thinks this is the right way. You have to imagine this entire thing taking place at a low, laid-back hum, because these are really not voice-raising people. It's like listening to a court stenographer read back the transcript of testimony: "Defendant then I called him a motherfucking bastard defense counsel did you mean it defendant yes I did defense counsel why did you call him a motherfucking bastard defendant because he took the urn with my mama's ashes and dumped it out in the garbage disposal defense counsel did that bother you defendant yes it did defense counsel is that when you punched him in the mouth defendant you're fucking right."
Ron and Chris are all over the 1 PM flight on EVA Air, and so are Nate and Jen, who are told about the same flight at the counter where they're standing. Both teams are told to wait while they check to see about availability. Meanwhile, Nick and Don get a 1:35 PM flight on Air Japan, where they seem to have headed directly when they got out of their cab.
Back at the observatory, TK and Rachel are still looking for the clue box, and she's still convinced this is the wrong place, while he wants to keep looking and not "cry about it." They literally walk right by the box, which is sadly sitting behind them, so hypnotized by their mellowness that it can only call out weakly, "Hey, dudes. Dudes. Dudes. Hey." They ignore the box.
