It had been more than a week since Lot 520 was staying in Keyller's condo and Keyller had already spent a lot of money. He even bought a new phone to use for Tagalog translation so that he could speak with her. The idea of buying a new phone was suggested by Kit. At first, he was against it, but the longer he used that smartphone, he realized that it was giving him a lot of convenience.
Keyller had just come back from Italy after Morelli summoned him for a mission briefing. After that, he went back to the Philippines to ensure that Lot 520 was still there. He asked Montejo and Hanabi to take care of the woman while he was away.
Montejo and Hanabi were people he knew when he was just starting in Foedus. He met them on one of his mission, which was also Trojan and Hanabi's mission. That's where all their friendship started.
