Idea for 2012 tmnt story, In the time travel episode when the turtles get sent back to the time where Tang Shen was alive what if instead of trying to keep the timeline the same what if at the very end when shredder shows up the turtles enter the fight and save Tang Shen and miwa.
I want a fic or story where they get stuck in that timeline and splinter goes off to New York (because he doesn’t know Tang Shen lived and didn’t see the turtles) but the turtles get to stay with Tang Shen and help raise baby miwa. Maybe Splinter does know about them and instead they all live together and Splinter try’s to rebuild the dojo and they try to pick their lives back together. However its hard because Splinter wants to find Shredder and get revenge for his fathers death. The revenge mentality causes some problems for Tang Shen because the whole thing in that episode was her debating on leaving Yoshi because she was afraid of raising Miwa in the clan and putting the clan before her and Miwas happyness and safety. (At least I think that was why, its been a while sense I watched the episode) I know the story probably wouldn’t work because we are going by Back To The Future logic in that episode but it be pretty cool.
Plus the Turtles can get to dive into their Japanese roots and learn more about there fathers culture. We get more baby Miwa with turtles content. And we get Tang Shen being a motherly figure to the turtles.
It be funny if maybe Renet did come back and was off by a few years and finally comes back to pick them up like a dad finally coming back from the store after a decade of absents and having basically a whole life time.
Another idea, story after the death of Splinter. Renet comes to hang out with the turtles cause she has a day off and Mikey is telling her about how he misses Splinter so Renet sends all the turtles back in time to where splinter has the baby turtles so that they can all hang out with Splinter one last time and get some closure.
