Joe and Sam moved to the next room; it looks like only 1 coffin is in this room. There are a lot of treasures on the sides of the coffin (Gold Bars, Gold Coins, Pearls, Jades, Vases, Chest Boxes).
Joe thinks if all these treasures are his then he can retire without worries, but he says in his heart he shouldn't; because these things belong to Zen. He is the Mansion owner along with his 2 brothers Zac and Zack. (What Joe is thinking, is normal.)
Sam asks Joe, “Can he keep some?”
Joe says, “Better, not unless you want to be dead.” Joe continues to say, “Unless we clear this place and no other traps, I can ask Zen to let you have some of them as a souvenir and to give some to Nic.”
Sam hears this and says, “Thank you, Joe.”
Joe shakes his head at how this guy can be so greedy, but he just thinks the same, too. So he is no different regarding treasures, money, or antiques. Joe just thinks he shouldn't say others when he is the same.
