I am writing a story in which four teens are given miraculous powers in the aftermath of a storm. One can become invisible, one has super speed and strength, another has the power to harness electricity, and the last one can manipulate people into doing things with her words. I just realized that the first "use of powers" does not come in until midway through the fourth chapter and even then it is just the teen with manipulation telling a bouncer to let them into a club. I drop "mentions" of it before hand, such as mysterious murders involving electrocution that have been troubling the city (one of the teens is the antagonists) and a couple vague arguments between the protagonists where they use the word "gifts". The teen with invisibility mentions sneaking into the local precinct, though he doesn't mention how. I realized that in my outline the first "fight" in a story that I planned to be very action driven does not occur until Chapter 6. Am I holding out on my readers who were interested in the fantastical elements of the story by not including more scenes earlier on? I've been reading books of a similar genre and noticed that they are often more upfront about character abilities.
