Loid was in an alleyway after defeating the terrorists that were-well-terrorizing the area, they were blowing up buildings, shooting and kidnapping people, and killing. It made him sick to the stomach. They had taken innocent lives, some of those lives even being the ones of children. Either because of belief, or because they simply wanted to.
He found it insane how people went to such extents to satisfy themselves. He was glad he had killed them, and honestly, he hoped they would burn in hell. He had just taken out the bomb the could've killed him, and many others in the area if it wasn't for Anya giving them a heads up..which he was curious about, how did a 6 year old know something like that would happen? He was contemplating that to himself, while being clueless about one thing: He left a terrorist out. They had kept themselves hidden, and Loid hadn't found out. Thus, he couldn't take them out.
He was about to check on the city and its citizens, along with Anya and Yor, that was until he heard something from the apartment which he had killed the terrorist in, and deactivated thebomb in as well. He was about to leave and decide it was a curious animal, maybe one who smelled blood, but his gut told him otherwise. He was just being safe, right? Right. He quietly went into the apartment, making sure his gun had ammo just in case he needed it as he walked into the room where he heard the noise, staying behind the wall as he peered over. And he was soon glad he trusted his gut because, sure enough, he found someone.
