Now that Bieber is gone, the rest of the team is trying to figure out how to get out of the hole. They're not sure how to do it, but they're going to have to figure it out. The only way they can do it is to catch Bieber, because he's the only one who knows how to send a signal to the moon. They have a riddle to test this out, and it's basically: "i shall descend from thy throat into thy esophagus, and with me, you shall rise your arms and expel darkness, and i shall forever welcome remain thy slave" . Hmm...that's a little cryptic, but hey, that's just the way it is. They finally have a clue: Otto Kmper, the head of the dignitary site, wrote about it in the journal they found on the ship. It turns out that Hamish used some of Hamish's son's military identification code when he fought in the Third Gulf War .
