So, Oliver was always supposed to end up the show dead. Only, now we've had seven seasons of him being put through hell in both past and the present, so 12 years in total, and he somehow managed to start a family along the way only to be torn apart from them with alacrity. Following this, the show still ends with him dead, only 50 years in the future to align with that Flash bit about him living to be 84 years old. And his kids (Lucas possibly, hopefully included) and maybe even the next next generation visit his grave, or better yet the original foundry. There, even SA gets his death wish fulfilled, and I can be satisfied with the knowledge that Oliver got 50 good years before his time came.
