Fiora couldn't outright kill a kid so most likely she would have to make it look like an accident. In Grimoire Heart it was pretty common to teach that since they were supposed to be all super duper secret. There were a bunch of things that could happen like pushing him into the streets and having him trampled or maybe a cart would hit him and it would run him over and he would be toast. Another thing he would be able to try would be if he was climbing stair at all she could push him and that would be all she wrote. Reagan Hullston saw that she understood so he headed out to the streets in Hargeon Town and would start to walk towrads the dangerous areas that were in the town so she could go to work. The first place would be the Hargeon Market street which had a lot of things that could caused the death of this page boy if you were creative enough. Fiora would then go and she would follow the page that was following Reagan Hullston and the dance with death was about to begin. The only question would be how would Fiora do it. She was always playful with her methods so she couldn't wait to try them out on this stupid page boy and get him killed
