"Aw yeah welcome to my crib girls." Michelangelo says as the group arrives at their destination
"Where are we?" April asks.
"Hey it's our Fortress of Solitude." Donatello says.
"Our Hogwarts." Michelangelo says.
"Our Xavier Academy." Donatello says.
"Our next generation state-of-the-art WonderDome!" Michelangelo shouts.
"Are we in the sewer?" Alexis asks as she sniffs the air slightly.
"Technically yes." Donatello says as he removes the bags from Alexis and April's heads as a giant rat comes over.
"You brought us here April." The rat says.
"Splinter?" April asks as she goes toward the rat.
"How does she know his name? Did you tell her his name?" Leonardo asks.
"Maybe she's clairvoyant." Donatello says.
"Maybe she's a Jedi!" Michelangelo says.
"She's not a Jedi but she definitely is something." Alexis says as she goes over to April.
"Come closer. It's been a long time. Mmm. You always did have your father's eyes." Splinter says as April and Alexis go over to him as the brothers follow.
"I don't understand." April says.
"Don't be afraid. All will be made clear." Splinter says.
"This is crazy." April says.
"Glad you think that so too." Alexis says as Splinter looks at her.
"And who is this?" Splinter asks kindly as he looks at Alexis.
"This is my younger adoptive sister Alexis Hathaway." April says.
"Wait. Adoptive? So you..?" Donatello asks as Alexis looks at him and nods.
"Yes. I lost my parents at a young age. I was found by April and well she took me in." Alexis says.
"Very much like your father indeed." Splinter says as he smiles.
*Timeskip*
"Listen closely April. I don't remember a time before living in that laboratory. That fateful night started like any other. Sacks gave us our injections. Your father made sure our vital signs were strong. And you as always provided us with a special treat. After the brothers went to sleep I heard loud voices. There was the smell of smoke. Alarms sounded. Your father had discovered the truth behind the man he was working for. He set fire to the lab. His last breath was taken trying to destroy Shredder's plan. I was terrified. But then you appeared. And ushered us to safety. I never had a voice then but I thank you now April. Mmm. We wandered the sewers until I found this place. It was then that the mutagen that was injected into our blood began to change us in miraculous ways. I saw how your father loved you and I knew I had to show that same love to the turtles. I became their father and they became my sons. Like all children they were drawn to the distractions of popular culture. And I knew one day they would want to explore the world above. They would be ridiculed. They would need to learn to protect themselves. Both mentally and physically. And then I found a way. First I would teach myself the ancient art of Ninjutsu. The brothers followed my lead, accelerating at a wondrous rate! Their gift was also their passion. They lived, breathed and dreamed all things martial arts. Then they were ready. Everything they are and everything that they've become was made possible by the bravery that you displayed on that fateful night." Splinter says as he is sitting with April while Alexis is standing with the brothers.
"I was just a little girl." April says.
"And you gave us freedom where others would have kept us in cages. You gave us another chance just like you did for Alexis." splinter says as he gestures to Alexis.
"Wait a minute, Dad. All these years you told us we were rescued from the fire by a great guardian spirit the Hogo-sha." Leonardo says as Alexis looks at April.
"That's right. And this is the Hogo-sha." Splinter says as he gestures to April.
"What?" April asks as Donatello Leonardo, and Michelangelo bow to April.
"My girlfriend's totally the Hogo-sha." Michelangelo says as Leonardo hits his arm.
