Most of the plots for the third season I came up with. And with the help of some fan-made plots, I was able to combine 3 and 4 seasons. That is, what ended in season 3 continues in season 4. For example: Fighting dark forces. In inventing the plot, I was not afraid of bad endings. Of course, there must be good endings, but in some cases a bad ending is also needed (that is, the hero dies or an important character dies, etc.). Initially, I had this in mind: In Season 3, Jake, his seed, and Rose move to Paris. There I could put difficult opponents (then I did not put bad endings). I started to put a bad endings after the plot:Jake and his loved ones are fighting the dark forces. As soon as I read the plot of Jake and his loved ones against the dark forces, I changed the plot. In fact, the plot for the third season was somehow weak and uninteresting. I'm not sure that now the plot is good. But still this plot is better than at the beginning. In Season 3, the hero (Jake, Rose, etc.) will not be at risk. Of course, sometimes there will be dangers, but not always. But in the 4th season, the danger will be two or three times greater.
