Light gritted his teeth. The man's name was Ryujin Rise, and his son Tenma Rise. He knew next to nothing about the both of them, so while everybody was glued to the TV he slipped off and and looked up Ryujin on the Computer. Ryujin Rise, of the company Ryujin Technologies, based in Sakurami City. A famous innovator, similar to companies such as Apple, who had created revolutionary items to make life easier for people. After his father had died of natural causes a few years ago, he had taken over the company. His son was obviously a great joy in his life, considering public photos. He wasn't married, and...his mother. His mother was dying of a rare disease, that killed slowly. It was time to act on that, then. Being a CEO was busy work, so it was safe to assume he had his cell phone on him. If the man had enough stones to kill his son in the name of justice, how would that make him any better than the way they portrayed Kira? It wouldn't, obviously. His policy was to kill criminals and not kill based on the fact someone MIGHT kill. There would be no good people left, otherwise. So, if his mother died in her sleep, it would weaken his resolve as to the fact that he would have noone left. Not to mention that killing his son would be HIS decision, Kira was only the one who laid down indiscriminate judgement. Ryujin would have to live with two of his closest family members dead in one day, lose his father's company and go to jail, the operation would fail, and he would still be free, barely lifting a finger.
Light took out his old Pocket Watch. He stealthily wrote down Ryujin's mothers name, then flipped it closed. In just 40 seconds his mother would pass away. If his cell phone was on him, it would ring a few seconds later, informing him of the death. If he was able to rightly predict the reaction, the man would break down, unable to do it. If he did still kill the boy, nothing would have changed. Ryujin would be taken to jail, and then die by the Death Note a few weeks later. He'd truly rid him from the world, absolutely having a reason to kill him, just it being less suspicious. In both scenarios, Kira had not done anything, at least not while being put on the spot. He waited silently, walking over to see the results on TV.
