Maybe, but I also feel like the brothers will form a tighter bond, and really accept Leo as leader, they'll probably go right back into training once Leo is better... intense training, because they'll have to go back and fight for their city.

As for Splinter... yeah, he will probably find Leatherhead at some point, maybe even Slash, that would be cool... Karai would almost certainly join him if it came to a resistance... the other thing is, what if the Kraang are rounding up mutants again, like they did in Metalhead rewired... so maybe Splinter will wake up in a mutant detainment facility... tho, if that were to happen, I wonder if the KRaang would just hand him over to Shredder -- as we know, the Kraang don't always honnor their arrangement with Shredder or the foot clan -- Kraang subprime was planning to whipe out the turtles and only deliver Splinter (which would suggest the plan all along was to kill the turtles despite Shredder wanting them for himself).

Anyways, that's probably more unlikely then Splinter and Leatherhead + various other mutants forming a resistance.
