Plot
Lillie is constantly concerned when she notices how exhausted and worn out her brothers are whenever they come back from patrol, despite everything they still do what they can to make their newest little sister happy. Lillie then decides to team up with Linda, the turtle's younger sister, to make the brothers happy.

Linda (The Oc) belongs to Jade45588, give them a follow if you can!

Lillie was currently sitting on top of the half pipe as the girl stayed quiet, swinging her legs back and forth while she looked down before she looked up as the kid was lost in her thoughts for the time being.

Lately she had been noticing how differently the brothers would act whenever they would come back from patrol or missions, even couple of times where she'd see Mikey tuck himself into his shell or Leo being sick to his stomach from the stress after such wild and near deadly night missions.

Lillie carefully got down from the half pipe and she then went to the kitchen to grab a snack but to her surprise, she wound up finding Linda in the kitchen. Linda was the turtle's younger sister which made Lillie the second youngest sister in the lair, Linda was a mutant turtle like her brothers and she was a different species of turtle as well, a southern painted turtle to be precise.

Linda wore a cyan/teal colored mask that had long mask tails much like Leo or Raph's mask only this mask had two small cyan diamond shapes almost under the eyes of the mask, a teal colored scarf around her neck with matching fingerless teal gloves and knee high toeless footwear much like Leo's. Linda gave a gentle hum to herself as she was also grabbing a snack but she sensed another presence, looking behind her as she spotted Lillie.

"Oh, hey Lillie. Everything okay?" Linda asked, she grabbed two cookies from the cookie jar while Lillie walked over and she leaned against Linda with a small but sad sounding sigh. "Not really.." Lillie mumbled.

"Okay, I'll bite. What's on your mind Firefly?" Linda asked, holding out a cookie for her as Lillie gently grabbed it and she looked a bit distraught as she then glanced at the cyan masked turtle. "I'm just worried.. they try so hard even though they're always exhausted. I hate seeing them like that..." Lillie said.

"You mean the guys? Yeah, but they're doing it because they still want to try and make you happy. If I'm being honest here Lil's, I did the same thing as they did a handful of times. I'd always push myself to my limits and they would be so worried about me, telling me to take a break. So I know what you're feeling." Linda said, she took a bite of her cookie and she then softly patted Lillie's head as Lillie made a cute hum when her head was patted.

Lillie then got an idea forming in her head as her bright orange eyes lit up, she turned to Linda as she held her cookie in one hand. "I got an idea, but I need a bit of help! Let's surprise em'!" Lillie chimed.

"Ooh yeah! Let's do this, sister team up time!" Linda smiled and she high fived Lillie as the two got to work on their plan to surprise the brothers for when they got back from their mission tonight. After about four hours, the boys were coming back to the lair as they looked beat.

Donnie was carrying Mikey who was tucked into his shell as the soft shell himself looked rattled up, Leo however looked pretty shaken up and the poor red eared slider seemed like he was about to toss his cookies any second while Raph seemed even more mentally drained after tonight. "Never. I repeat, NEVER make me do that again." Donnie said, he shivered a little and he then looked over at Raph.

"It wasn't that bad.. right..? At least we got out in one piece.." Raph tried to look on the bright side but it was a bit hard as Leo gave a quiet groan, he wanted to just crawl into his bed and hide there for the next few hours. "Barely! I saw my whole life flash before my eyes! In retrospect, it was really boring.." Leo said.

"Hey guys!" The boys looked over and saw Linda walk over as the younger sister gave a small smile, having a small can clear soda in one hand which she tossed to Leo as Leo caught it. "Thanks Lin." Leo thanked her and cracked the can open, taking a few sips as it helped settle his stomach down.

"So.. how'd it go?" Linda asked, crossing her arms over her chest as she then looked over at Mikey's shell and Donnie then back at Raph who winced a bit but explained that they managed to complete the mission despite all of them nearly dying for who knows how many times in a row now.

"Well, while you guys were out. I've got something to show you, c'mon." Linda led them to the TV room and the brothers followed behind as they were a bit curious what Linda wanted to show them. When they got to the TV room, they saw a huge blanket fort had been set up, quite the multitude of pillows and plushies were around or in the fort too. There was several boxes of pizza stacked up, bowls of different snacks and a few different drinks too as the group saw Lillie carrying a plate of freshly made chocolate chip cookies as she took notice of the brother's return.

"Wh.. what's all this?" Raph asked, he looked at Linda and Leo was pretty blown away by the nice little gesture as Mikey popped his head out of his shell and he was certainly amazed as well as Donnie. "Well, Lillie's been kinda worried about you guys more than usual. So she and I came up with this, you guys need a break." Linda said.

"Yeah! I know you guys push yourselves pass the limits and even when you get so drained and tired after missions, you still come back with smiles on your faces after everything.. I just, I wanted to try and cheer you guys up..!" Lillie chimed, she looked at the brothers with her bright orange eyes as Linda smiled and she went to Lillie before she ruffled the kid's hair softly.

"Firefly ain't wrong, you guys had me worried too. But, for now you need to take things easy." Linda said, the next thing the two sister's knew however is that they were pulled into a group hug as Lillie gave a giggle since she was being nuzzled by Mikey.

"You two are the best little sisters a turtle could ask for!" Raph said, he looked at Linda and Lillie for a moment before he heard his brothers chime in.

"How'd we end up so lucky to have two amazing sisters?" Leo jokingly asked, he smiled a little as he seemed to feel a lot better after taking a few sips of his drink.

"But seriously though, this is a very nice gesture. Thank you both." Donnie said, the soft shell being genuine for the first time.

"Yeah! This is so cool, both of you are the sweetest sisters ever!" Mikey exclaimed, he looked at Linda and Lillie with a happy smile on his face.

"Aw, thanks guys.. now, let's kick back and watch some movies!" Linda said, eventually the hugged stopped and the group got to go into the fort as they watched some movies to unwind and relax.

Lillie ate a slice of pizza and she smiled a little as she saw Linda chatting with Leo for a bit while Donnie relaxed under the comfort of a weighted blanket, Mikey wrapped up in a nice fuzzy throw blanket as the orange masked brother ate some pizza while Raph laid back with a happy sigh as he had felt so much more relaxed now. These four brothers were rather lucky to have two caring little sisters in the family.
