Epilogue
After Kojiro's death and cremation at the farmhouse, the turtles and Splinter took a voyage to Japan, the land of their friend's birth, to lay him to rest there. Like they had with Splinter's master, Yoshi.
Leo was still wearing the sling on his right arm. But otherwise, he was doing fine.
Once they reached Japan, they went to stay with the Ancient One. When they took Kojiro's urn to the cemetery, he was placed by Yoshi and Teng Shen's graves.
"He saved us from becoming more of the Shredder's victims." Don said.
"He had a brother here in Japan too. At least he's with him again." Leo said.
"And I appreciate that he had saved you two." Splinter said. "I wouldn't have you two here to keep Raphael and Michelangelo here in line."
"And we sure could use Leo's leadership and Don's smarts." Mikey added.
"Us four are a team." Raph said.
"We need each other to hold the family together." Leo said.
The family came home shortly after. Life went back to normal. They had to move on with their lives. They would always be on the lookout for Shredder and his ninjas. The Purple Dragons and the Mob, Bishop. And even new enemies that had yet to pop up.
Don worked on his inventions, fixed things, fixed injuries. His nightmares were beginning to diminish a good deal. He tried not to let it bother him. He had a lot of things to do, to catch up on from when he was injured.
Leo lead, meditated, recovered from that injury. It left a good sized scar on his arm. But Don's treatment made sure it healed right. He had been more than anxious for the all clear in training and fighting again.
Raph punched his bag in the dojo, ran all over the city with Casey or by himself. Beat up bad guys. He still remembered almost losing Leo and Don. He tried his best to not get upset with Leo, but at times, he couldn't help it. He would always have a hot temper.
Mikey went on cooking, reading comics, watching TV, and playing pranks on his brothers. His bros often disapproved of the jokes he pulled, but he did make them laugh when they needed it, if not all the time.
Splinter was still glad he had all four of his sons. He meditated in his room and watched his soap operas. The news. He would watch his sons train. Give wisdom and advice when needed.
The scars on Leo's and Don's plastrons were still visible and would leave their calling cards for life. They just never wanted to go through anything like that for the rest of their lives.
