Some TMNT stuff really isn't for little kids.
After being bullied by a couple of fellow mutant children, Lita runs off, crying. Jennika gives her a pep talk, recounting the words of Splinter, who told her that she is ninja, and that this applies to Lita, too, and that he said "you are the future, and the future is limitless". Just then, a grown-up Lita appears outside the farmhouse with the Time Scepter.
Lita finally finds the Splinter Clan at the dōjō, bringing dire words of a future where the Splinter and Foot Clans clash, resulting in Jennika killing Karai and the rapid dissolution of Lita's family. She leads the Splinter Clan to where Karai's helicopter had crashed, and they rescue her, Koya, and Bludgeon from the wreckage and bring them back to the dōjō.
Owing to Leonardo and Koya apparently being an item before his disappearance in her timeline, Lita addresses Koya as "Auntie", much to the falcon's bewilderment and disgust.
