Own initial idea submitted to group for consideration

My ideas for the opening sequence were firsty that we should use two characters in a school commiting a crime which is escalating and has no good end for one of the persons I also came up with the idea that in another story there is a pro- and antagonist in the story who are having an argument. We finally used this rough idea and had to develop it as we needed to think about the story, props and also the location.
