Everybody loves Leo Valdez right? Everyone loves the insane idea of him jumping off a building, engulfed in flame and flying, right? The thing is, Rick Riordan could have been in deep waters when he came up with this scenario. For one key reason. "Flame on!" This was what was said that he would use. The thing is, this phrase belongs to Marvel. The Fantastic Four has a member called the Human Torch. In the 2005 film, he jumps off a building, sets himself alight to attract attention from a heat-seeking missile, and yells "Flame on!" Anyone else see the problem with this?
