Within the Renaissance Dojo, Yoshi and Tang Shen were taking part in what had become an almost nightly ritual between the two of them to wait long into the afterhours for their children to come home.
Both were nursing a cup of tea that had long gone cold, and were waiting for any sort of news about their children's well being.
Leatherhead had called in earlier to report that his search of Kraang facilities had come up empty. It seemed that the Kraang were smart enough not to reuse the places their enemies already knew about, making it that much harder for them find them.
But still, no word had come in from their children, and the couple was beginning to get anxious.
Then they both looked up as they heard the blessed sound of the key turning in the lock, and the soft chatter of five adolescent voices making their way towards them.
Tang Shen sent a beaming smile at Yoshi, feeling utter relief that her babies had returned to her safely.
But Yoshi was not so easily lulled into security. While he couldn't make out the words, he could hear the nervous mutterings of his children as they drew closer. They may have all returned home, but something had happened that night. Something that had spooked them, badly.
The two adults watched as the door to the kitchen slowly opened, and their five children filed in. Looking them over, there did not appear to be any outstanding injuries other than the usual scrapes and bruises one would get in a scuffle.
But then they noticed that Raphael had not fully entered the room, but instead remained in the shadows leaning heavily against the door. What was even more odd was the fact he was wrapped in a bulky, old-fashioned trench coat and hat that covered him completely.
Tang Shen's eyes filled with concern as she realized that something was clearly wrong. "What has happened?" she asked softly. "Why do you hide, Raphael?"
Their children shifted nervously, before Leonardo stepped forward into his leadership roll.

We, um, we didn't do too well tonight," said Leo, looking ashamed. "The shipment turned out to be mutagen. We… failed to stop it, and instead the canisters kinda… fell all over New York…"
Tang Shen and Yoshi exchanged horrified glances at this. They had seen what that substance could do, both to human and creature. For so much of it to be out in the unknown was a terrible grievance.
"But that's not the worst part," Mikey piped up. "Raph-!"
Whatever the youngest had been about to say was silenced as Leo and Donnie clamped their hands over his mouth, making whatever he'd been about to say be muffled.
Raph gave a violent flinch from his hiding place, and his siblings all shot him a nervous glance.
Now their parents were very alarmed. "What happened?" demanded Master Yoshi loudly, making his children stare at him with wide eyes.
Tang Shen stood and made her way to her third oldest, and reached out to him, only for him to shrink back even deeper into the shadows.
"What Has Happened to Raphael?!"Yoshi demanded again, concern for his son flooding him.
The five teens exchanged glances, before Leo took a deep breath and said, "Raph… he-he got… hit by one of the canisters. Hemutated, father."
Raphael gave another violent flinch, and at Tang Shen's quiet coaxing, slowly removed his coat and hat.
Yoshi and Tang Shen stared at the giant turtle standing in their kitchen with their son's eyes.
"Father… Mother… It's-it'sme," he said softly, knowing logically his parents wouldn't reject him, but fearing it anyway.

Tang Shen let out a tiny gasp, before throwing her arms around him. "Oh, my poor baby," she said as she held him tightly.
Raphael seemed to be in shock at the contact at first, before wrapping his arms around his mother, and hugging her back with an air of desperation.
Hamato Yoshi also came forward and placed a comforting hand upon his mutated son's shoulder. "What happened?" he said again, addressing his other children.
And so they told the adults everything
