Summary
Without needing to be prompted, Donnie and Mikey jumped through, the latter being supported by the former as he limped along - he’d be due for a medical check once they were all accounted for. Raph followed, expecting Leo to cross over and cut the portal off once they were all clear.
What the two of them didn’t account for, however, was the shrill noise that echoed throughout the ruined station, setting all four Mad Dogs on edge.
Or: Why doesn’t Leo use his portals in the future?

Summary
“How old is he?”
Leonardo pauses his stirring. He half-expected a joke—an innocent little jab meant to lessen the tension thickly clouding the kitchen—yet Leo’s voice is quiet, serious.
So Leonardo turns around and offers the same air of calmness that the teen approached him with. Yet his chest constricts when he has to angle his head down low to meet Leo’s eyes, and an overwhelming sadness withers his heart as he takes in that young, bright-eyed face. Leo is a child, a baby.
And he’s going to cause the end of the world.
Or, Casey Jones goes through the time portal, but he’s a baby in Leonardo’s arms. And one traumatized turtle juggles being a new dad while trying to prevent a horrible future.

Summary
Leonardo was the Leader of the Turtles, the oldest brother and extremely protective of his brothers. He was a focused and extremely skilled ninja. That's what everyone thought Leonardo was, but in reality, he was a Female Turtle forced by Splinter to pass himself off as male. He was forced to pretend to have a deep, masculine voice, which caused great pain in his vocal cords, and he had to endure Splinter's abuse completely alone. Leonardo wanted to be feminine, to be called a girl, not to have to feel a horrible pain in his throat and, above all, not to have the name Leonardo, which every time it was said caused unbearable pain in his soul. And her life changed when she found an injured vampire bat in the sewers and took it to her room. What she didn't imagine was that this was the Heir to the Vampire Throne and that he was more than in love with the beautiful Turtle who saved him.
