At the end of my novel my protagonist, Michael, has just seen his sister get engaged. Now for most of the story his prime motivation was keeping her safe, and his feelings about this are ambiguous. So he leaves the party and goes outside and muses things over, and that's how the story ends. Now my question is this: should he be completely alone in this last moment, symbolising the fact that the focus of his life has passed into the care of another? Or should he be joined by Jacob and Silwa, the new friends he made over the course of the story, symbolising the fact that he has found new direction from his life as a result of his experiences? I can't decide which one would be better, looking back to the old or looking forward to the new.
