You woke up from the noise of someone talking. Sitting up and rubbed your tired eyes. Master Splinter amd Leonardo were talking together, whispering so neither you or the other brothers would wake up.
"Leo?" You called out for the blue masked turtle while taking out your phone to check the time. It was late in the afternoon. Looks like you all got a few hours of good and needed sleep.
"Shhh, be quiet (y/N). I don't want the others to wake up." Leo shushed you and came closer. "I'm just gonna go to get a few supplies, you know, food and stuff. I'll be back soon." Master Splinter also approched you.
"You should go back to sleep for a little while (y/N). I believe you need it more than you think." He gave Leonardo a small glance from the side and you knew something wasn't quite right with this whole situation. You looked at Leo and in your head it went 'click'.
"No." You stated, a bit louder than you acctually wanted. A few feet away Mikey jolted up from his sleep.
"PIZZA!" he shouted and brutaly woke up his other two sleeping brothrs.
"Mikey, what the shell?" Raph grunted and punched Mikey.
Donnie sat up and yawned.
"Is it really time to get up?" He saw you and smiled. "Morning (y/N). So what's going on?" Quickly you got up and brushed some dust off your clothes.
"Leo and I were just on our way out to get some food and other stuff." You tried to comb your hair without any real sucsess but it would be okay. Smiling you turned to the turtles. "Any requests?"
"Bring some sodas!" Raph spoke up first, shortly followed by Mikey.
"Some Pizza for me! And something for Clunk. You know what he likes." He picked up the cat that was meowing around his legs.
"Okay, will do. We'll be back soon." You grabbed Leos arm before he or Master Splinter could say anything, and left the room.

Leo asked what exactly was going on, but you didn't stop in tracks untill you were far enough away from the others and turned around to him, before you spoke up.
"Don't lie to me Leo. You didn't just wat to get supplies. You want to go after Karai, that's why wou were talking to Master Splinter right?" Leo huffed, bit he gave you a surprised and impressed look.
"How did you find that out?"
You placed your hands on your hips.
"Leonardo, you are my best friend. I think I should know you."
"Well, will you stop me?"
"No." You shook your head and started to walk again. "You have the right to want... revenge. But please don't make a mistake. We just got you back and I think Master Splinter would be disapointed if would do something stupid again. I'll go and buy everything you guys need." You had reached the exit by now. "Go and pay Karai a nice visit and give her my greatings as well. I'll wait here for you when I'm done." Leo gave you a small smile and you two parted your ways.

-about 2 hours later-

You were waiting for Leo for already about 30 minutes and it was getting cold, so you got up and started to walk around. A few minutes later you hear someone approach your current location. From the shadows you saw Leo, and as you saw him smile you smiled back.
"I suppose everything went well?" You asked him. He nodded back.
"Yes, I told Karai to stay away from my friends and family. And gave her your greetings."
"Good. Now help me with these bags. I had a hell of a time getting them here alone!" You pointed at a pile of bags, each one of them filled to the top.
"Okay, okay, I'll help." Leo grabbed most of the bags and left you two of them to carry.

Minutes later you arrived back in the reservoir. The brothers and Master Splinter greated you both happily and you started to unpack the bags, handing out the food to the brothers. Thank goodness the pizzas you bought were still warm and you all started to eat together.
"Thank you very much for your help (y/N)." Master Splinter spoke up after a while of eating in silence. "You helped us find together again and brought us these supplies. I am very thankfull for this." You blushed a bit.
"I didn't do that much." You mumbled a bit embaressed.
"Well even if it was 'not much' I'm glad you did help." Donnie said, making you feel better. Mikey, Leo and Raph also thanked you. Mikey was especialy happy since he finally had food in his body again.
"Yeah, I think from today on you can count yourself as our sister!" He hugged you tightly and you tensed up.
"Mikey let go!" You tried to free yourself put of his grip. "You're crushing me AND getting pizza all over my clothes!" Playfully Mikey squezed you once more before letting go of you and joining into the laughter of his brothers. You glated at him before joining in the laughter as well.
Master Splinter smiled as he watched the five of you fool around while you were eating.

After you finished up there was only one more thing you wanted to do before you went home yoursel; It was getring late again and you really needed a nice and warm shower.
"Guys, Guys!" The turtles turned to you as you called out to them, while you took out your phone. "Let's take a photo before I leave." The boys agreed and grouped around you, while you held out the device to tale a selfie with the turtles.
"Now smile~" All five of you grinned into the camera and you took the shot.

For you this photo stated a new beginning for you and your friends.

IT'S DONE!!
Because I was asked to update I sat down yesterday and today to write this ending for you~ I hope you all like it ^^
For now I'll concentrate on my fast forward reader insert but I may start a new TMNT x reader story just for you.
I hope my writting isn't too bad, since one of my motivation here was to create a TMNT reder insert that wasn't written completly unreadeble (most TMNT reader inserts I have found in DeviantArt are sadly written pretty bad .__. )
Thank you very much for following me through this all this time!
