What’s an old idea that you’ve discarded?
In the beginning of Elements, I had written a scene about a boat crashing into a jet ski at the lake. It was mainly just a shock factor and used to lead into an event that I still kept but segued into differently. I decided to cut the boat crash scene because it was long and it didn’t do anything for the plot on its own. Plus I liked the scene I replaced it with much better and what I went with instead opens the door to carry that particular plot point throughout the series.
