dimension travel and time travel au where past Nightwing travels to the future in an alternate dimension to when Jason is alive again and the Red Hood (the timeline isn't different. the dimension travel is only so that younger Dick can stick around at the same time as older Dick without needing to go back to his time).
like im imagining past Dick who was beefing with Bruce 24/7 and pissed at him all the time, even more so after Jason's death (Tim isnt in the picture yet maybe), and hes suddenly seeing this doormat version of himself that just defends Bruce's actions or goes along with them to keep the family together.
like maybe past Dick is absolutely baffled at how the future version of himself isnt Jason's number 1 fan. because despite being an ass at first, by the time Jason died, Dick had absolutely adored him. so why is future him so okay with Bruce having replaced Jason before he was even cold in the ground? and why does future him even tolerate Tim when Tim was the one who brought Robin back after Jason? and why does future Dick even bother being in the same place as Bruce or Alfred after they both bad mouthed Jason and destroyed his image? why does he still respect Alfred after he spoke badly about Jason who had loved him when he was alive and after Alfred kept turning a blind eye to Bruce's flaws and mistakes?
and why is future him not all over Red Hood? Jason is back and hot and skilled and smart. hes sassy and competent. younger Dick is literally drooling over him and would sell his soul for a kiss. not to mention the fact that Jason's hair dye has grown out a bit and that is definitely vibrant red hair hiding under the black. and that white streak looks so good.
and its not like Jason became some horrible person when he became the Red Hood. he's still introverted, still loves to read, loves to learn. he still cares so much about all the people no one else seems to care about. he loves children. he respects women. he protects people. he still doesn't know how to accept a compliment. hes hard working too.
older Dick gets a serious reality check and realizes how much he has changed himself to conform to what Bruce and the family needed instead of staying true to himself and his beliefs. he had taken on the emotional responsibilities that should've been Bruce's. he contributed to Bruce being the way he was now by not stopping him.
and younger Dick sets the record straight about a lot of the false information that had been spread about Jason. he is also determined to land Jason as his boyfriend and does eventually succeed so hes having a blast in this new dimension. he has an amazing man (who makes fantastic food). and he doesn't have to deal with Bruce unless he wants to. and he gets to make sure he doesn't become like older Dick who he will happily lecture any time.
