Dick quits. In every future, Dick gives it up to have a normal life, as is his right, and someone has to pick up the pieces. And every time, no matter how much he didn't want to be doing this shit his entire life, and no matter how much doing it takes from him time and time again, Tim steps up
This sort of thing is exactly why I don't like Tim these days. These alternate future stories never happen and Dick has to be written out of character or dumber than he is so that Tim can shine. I've seen people literally argue that being able to hack or use a computer is a Tim thing. All Robins use computers relative to the time that they were the current Robin. Dick used the computer all the time in the old comics and even in the 60s show. Even if dick isn't Batman he is going to be something and be working to help people. Tim also has a habit of going off the deep end in future timelines. But they don't matter IMO. Tim is not going to become the Savior or Joker.
Dick has been a super hero his whole life and comic writers try to push him as being the "normal" Batman character when he is absolutely not. Traveling circus kid raised by billionaire is not a "normal" life. The guy grew up doing super hero stuff with super hero friends and DC never seems to want to let that be a factor in his life. All of these new supporting cast and professions don't really work with the character. He always one way or another returns to the Batfamily and the Titans. Dick strangely enough is one of DC's most misused characters. Timeline is forever screwed and changing due to new gen people and reverse aging Bruce, has basically no modern Robin runs, constantly used to prop up new characters, and constantly has his creatives taken from him when he is doing well.
Also, The new teen titans, Batman reborn, Grayson, and that one alternate future story where he is the basically the super police are all great examples that no matter what name he is using he is always going to be a hero.
Also I'm so sorry about the huge posts I keep posting.
