Alias: "Double Labyrinth"
Timothy Drake, aka Bruce's third adopted son, who comes from the most perfect and peaceful world of ordinary people, has transformed back into the year when he was seven years old and attended the Wayne Charity Gala. However, the strange thing is that he has difficulty finding two adopted brothers. After confusingly searching for information, the only clue he found was that Bruce Wayne had a thirteen-year-old illegitimate son, Damian Wayne.
All are AU, Ordinary Tim's Hell starts in reverse order, the main line is batfam line. It's a hodgepodge of many worlds. There is no CP humor, the drama content depends entirely on your mood, so please feel free to eat.
Concept: Love can be quantified by the laws of the universe.
