Unfortunately, Kaitlyn's death had nothing to do with Hannah at all. At the time, Hannah was on vacation abroad, spending the money Jack Handerson had given her.
Riki didn't know how deeply Jack loved Hannah, to the point of becoming blind and willing to do anything. In fact, according to the latest news from Leon, Jack's wife was planning to divorce him. This was immediately after Jack was thoroughly questioned yesterday. It was clear that Jack's purpose in sending Hannah on vacation abroad was to keep her out of legal trouble. Unfortunately, Leon had already left for the country where Hannah was vacationing that morning.
In essence, Kaitlyn's death was purely due to fate. If the girl had not been destined to die at that moment, Riki would have received a mission from the system to save her.
However, the system has limits when it comes to matters related to human destiny. Especially death or birth.
