But really, I prefer the idea of Splinter sticking around long enough to know his grandchildren or great-grandchildren (adopted or otherwise).

TMNT in general needs even more cross-generational dynamic spanning three generations instead of just two. That banter between Splinter and Raphael about the difficulty of raising children is always worth a smile. But it's not just characters like I'm thinking of, but also Leonardo's daughter Yumi from his vision of another life. Though it wasn't necessarily possible for Yumi and Splinter to directly interact, it's nice to think of Leo having that kind of daughter in this lifetime.
