Natasha and Yelena decided to go into the lane pools and race. As predicted, Yelena won. And then Kate joined them. And...she beat both Black Widow sisters. They may have been the better fighters, but Kate was the far superior athlete. Meanwhile, Lila and Cooper went back to their family, and upon seeing this, Natasha, Yelena, and Kate joined them. Clint told his two oldest, "I'm so proud of you two. Lila, you didn't hesitate to fight back against that creepy bozo. And Cooper, seeing you throw his ass out...I raised a great boy. I love you two." Lila smiled, "Cooper has always been caring like that." Cooper replied, "Of course, but you did most of it. It's nice to have a badass little sister. It must be nice to be the badass of the kids." Lila laughed, "Me? Dude, you're just as much if not more than me. You've saved my ass a couple of times."

"That's a-" "Like that time where that one guy tried to throw the ball at me on the basketball court, and you beat him up and were sent to the office?" Cooper laughed, "And then dad got that scrapped from my record. But you're a badass yourself. Like when that girl in your grade pushed Nate and you gave her the beating she deserved. You're the badass of the family." Lila decided to pull out the big guns. "Did you forget about that time you literally carried me out of the pool when I had that stomach cramp?" Kate suddenly asked, "Stomach cramp? Why were you swimming when you were on your-" Lila laughed and quickly told her, "Not that kind of stomach cramp. We had some sodas, and I, unfortunately, drank a passion fruit drink because I thought it sounded cool. It made my stomach act up, and after Cooper got me out of the pool, we quickly changed back, which was very difficult for me to do." Cooper finished the story, "I called my dad, and we met at the clinic. We found out that Lila had that reaction because she was allergic to passion fruit. I was glad my baby sister was safe, and that it wasn't worse than it could've been." Lila rolled her eyes jovially. "Okay, Cooper. Now you're pushing it. Baby sister? Boy, I'm only two years younger than you." Yelena laughed. "Yeah, you two don't have a big age gap. Unlike me and Natasha, or you two and Nathaniel." Nathaniel laughed, "Yeah, I was happy Lila ended up being okay." Laura added, "He loves his big sister. He was crying the whole way when we were driving to the medical center!" Nathaniel covered his face in embarrassment, causing Lila to smile and hug him. "It's alright, lil bro. No one is judging you for it." Cooper hugged from the other side, "Yeah, this just shows that you care about your sister. And that makes you a great brother." Natasha shed a little tear. Kate asked, "You good, Nat?" She said, "Yeah. It just really makes me happy to see these kids and how much they love each other."

Lila noticed Kate only eating a small salad. "Kate? Why are you only eating a small salad? These nachos are so good." Kate smiled, "Force of habit, being an athlete and all. I try to stay lean, and not bulk up too much. Your metabolism won't be as fast as it used to be when you hit college." Lila said, "Well, glad I've got one more year left. And besides, I'm not a boy, so I don't have to worry about overeating. I'll hopefully be able to maintain this flat stomach for a while." Nathaniel asked Lila for some, so she let him finish the other half of her nachos. Clint said, "Yeah, for sure. My Lila does not eat as much as my boys. This one, Cooper, he especially eats a whole lot."

"Dad, I have to bulk up! And it's not my fault you buy so much good meat! Oh wait, it actually kind of is." Laura asked, "Yelena, Natasha, Kate, do you guys like hot dogs?" Natasha talked, "Me and 'Lena do, Kate not so much."

"Well, my husband and I make really good ones. All three of our kids like different condiments on it." Simultaneously, the three kids stated their favorites. Cooper's was ketchup, Lila's was mustard, and little Nathaniel liked mayo. Natasha and Yelena looked at each other surprised. Kate chuckled, "kids." Kate looked at Nathaniel. "Little Nate, I know your sister and brother have their favorite sports. What about you? You doing any sport yet?" He said, "Baseball. Cooper is really nice and even though he doesn't play, he still helps me with my pitching." Kate smiled, "Yeah, sounds like Cooper. He seems like a good older brother." Lila quickly responded, "Hell yeah he is. Even if he can't cook." Clint teased, "Damn right he can't." Lila said, "I'm gonna go off the diving board now. Cooper, get a video of it." She walked towards the board, and climbed up. She was doing the 10 foot dive. She passionately screamed for joy as she flipped off it and landed feet-first into the pool. She swam back to her brother and saw the video. "Aw yeah, this one's good." Cooper said, "Now you get me." He went backwards and did a backflip off the board. He swam back to Lila and she said, "Man, yours looks so much cooler." He said, "it's alright, sis. Sometimes I have to be the more badass one. So, what do you say? Wanna play some family water basketball?" Lila smiled, "I'd love that. Let's get everyone except for mom." They called them over, and they all got up to join them. Laura took a few pictures of everyone together. Natasha had Lila put her arm over her belly, to cover up the scar. Laura would continue taking pictures of them throughout the day. Natasha said, "Make sure not to hurt each other with sibling rivalries!" Nathaniel told her, "Don't worry, auntie Nat. Cooper and Lila are way too caring. Cooper is a better fighter than Lila, so once when he was training her, her accidentally hit her right here." He tapped on his ribs. "Cooper felt so bad about it, he was almost crying." Lila added, "He's a strong guy, but I kept telling him that it was okay. I knew it was on accident. It was my fault for blocking the wrong way. He shouldn't be blamed for being the better fighter." Cooper teased, "And Lila is a tough cookie herself. Like that time she gave me that bloody nose!" Lila quickly responded, "I'm sorry, I didn't mean to hit that hard!"

"Heh, don't be. I should've been able to block it, you were just too quick for me." Cooper then pulled Lila aside, "Lila, just to make sure, you're feeling good, right? Didn't eat anything you're not supposed to?"

"I'm at 100%, big bro. And also, I only ate like four. I was wanting to ask you to play for a while so I made sure not to eat too much." They were suddenly interrupted by a weird growling noise. Cooper, knowing too well, said, "Aunt Nat? Is that you?" She said, "Sorry, kids. I just had to listen. But my tummy decided to give me away. It let you guys know that I had some beer here." Nathaniel, having no filter said, "Well, tell your beer belly to be quiet when we play." Natasha looked down at her belly sadly, and Cooper said, "Shut up, Nathaniel. You can't say things like that." Lila said, "Yeah little bro. I'll beat you up if you make fun of auntie Nat again!" He quickly walked away, next to Yelena. Natasha said, "Kids really don't hold back..." And once she was the right distance away, Lila pulled her brother back and said, "man, I feel really bad but that was funny. I had to try not to laugh." Cooper responded, "I'm glad you've gotten better at that. But at the same time, I am surprised. Aunt Nat has definitely gained some weight." She agreed, "Yeah, glad you can actually say it in a good way. If I ever gain too much, will you tell me?" Cooper laughed, "Please, lil sis. You're fine, and very good about your health. I'm proud of you for that." She said, "Thanks. Part of it is that I'm good about health, but I won't lie. My body image is another thing. I don't want to look fat or...I don't know. I just wanna look good. Sorry if this is too much information." Cooper assured her, "It's not, don't worry. It actually makes me feel good that you're okay with talking to me about this. I love you, Lila."

"Love you too, Cooper. The last one to the pool is the loser!" They both dashed towards the pool, with Cooper outrunning her. However, as Cooper jumped in, Lila did a forward leaping dive and landed in the water at the same time as him. Volleyball definitely helped her learn that. Clint laughed, "I think it's a tie. So what do we say? Me, Nat, and Yelena vs. you four?"

"It's on." Cooper told them, "We've got Kate on our team, I think we're safe." Kate told them that she'd guard Yelena, and Cooper said, "I'll guard my dad, since I'm taller so it'd be best for me to do it." "I'll guard aunt Na-" Nathaniel quickly cut his sister off, "I'll guard auntie Nat." She asked why he wanted to do it. He said, "You're a better passer and shooter than me. I can guard auntie Nat to leave you open. It'll be hard for me though." Lila pulled him aside, "You're still a little kid, so you know it'll be hard, right?" He nodded. "Just...don't tell ANYONE I told you this, but remember her weakness." And she quickly went back to the others, and Nathaniel realized what she meant. Kate asked, "What were you saying?" "She told...uh...said that...I...um she-"

"I told him that it will be hard so he should always check his surroundings." She gave him a big sister glare, making him keep his mouth shut. They all got in the water, and Lila threw the ball in the air. Cooper used his reach advantage over his dad, and took it. Kate tricked Yelena by splashing on her left side, but being on her right. Cooper passed to Kate, and she scored for them. Next, it was the grown-ups' turn. Yelena passed to Clint, who barely caught it with his son guarding him. Nathaniel was behind Nat, and knew what to do. Clint passed to Nat. She noticed Nathaniel down in the water and slowly walked over to him, fully standing in the pool. "Nate, are you okAY-" And he poked Natasha in the navel very hard, causing her to drop the ball. He took it, and threw it to Lila with all of his might. She threw it to Kate, who passed it to Cooper, who made the shot with relative ease. Cooper called a time out, and bent down to whisper to Lila, "Did you tell him to do that?" She nodded while laughing. He shook his head and said with a chuckle, "You're such a bad influence." She said, "I mean, she told us herself. And it's an easy target, so he can know to help us win."

"Easy target?" "I mean yeah. I love her but it's true that she has a bit of a potbelly. Man, I feel this pain inside even saying that." Cooper looked confused and asked why. She said, "She's my auntie Nat. Saying that about her makes me feel bad." He sighed. "Will a hug make you feel better?" "Sure. Thanks big bro, you know me well." He gave her a nice hug, and after the hug said, "Alright, ready to keep kicking ass?" and lightly hit her in the stomach. She punched him in the stomach and said, "Ready." Cooper slightly reacted and said "Damn, you really are getting stronger." She shook her fist and said, "I couldn't tell, you work out too much. But yeah, let's go." And they continued embarrassing their dad the sisters. Eventually, they'd lost count of how many times the kids had scored, when Clint said, "Alright, kids win." As they all climbed out of the pool, Lila groaned in pain. Cooper, noticing where her arm was, freaked out. Lila said, "My stomach...it really hurts..." Cooper cried, "Was it the nachos? The only drink you had was a lemonade this time!" She got up and said, "Got you!" while laughing. Cooper pushed her into the pool. When she got out, she said while laughing, "I had that coming, don't worry guys." Cooper said, somewhat annoyed, "Lila, you're my little sister. And my best friend. I love you a lot, so please don't scare me like that." She said, "Fine, I'm sorry. Love you too, Coop." Clint and Laura looked at each other and shook their heads while smiling. Natasha said, "Actually though, my stomach isn't feeling too great." Yelena sighed, "Tried to warn you." They all laughed and enjoyed the rest of their time at the park.

Then, Kate and Yelena started talking about what movie they should watch, and came to a disagreement. Kate said, "We should watch Indiana Jones!" Yelena disagreed, "No, we should watch Frozen." Yelena got an idea, "How about we do a 1v1 fight back home to decide the movie? First to submit wins. Also, we don't change. We fight in our current clothes." Kate looked down at herself confused, and asked, "You...want to fight...in...bikinis?" She nodded. "Less protection. Also, Laura, record this." Clint said, "This is quite the difference. Yelena has much more experience here..." Kate reminded him, "Don't worry, I'm a black belt. And I've fought more recently than her due to my college karate clubs. And since I lost to Natasha and know a bit more on what to do, I think I'll be fine." Lila added, "And...you have age on your side. You have a six pack better than many guys that I've seen, a-" Yelena said, "And I have a potbelly." She slapped her belly. "Don't worry, I fill up my tummy to give Kate a chance." She drove her fingers down Kate's ribs, making her a bit uncomfortable. "And sometimes, being lean can hurt you." And she tapped on Kate's rib pretty hard, which hurt a little. She responded, "But sometimes, this," as she poked Yelena's belly button, "can get in the way too." Yelena nodded, "We'll see, Kate Bishop."

It felt awkward at home, several guys seeing two women fight in bikinis. Kate wasn't entirely comfortable, being recorded while fighting in a bikini, but she was ready. Laura started recording. "Ready, fight." Kate got in a defensive stance. After successfully blocking hits, She did a leg sweep on Yelena. Yelena got up, and after her fists were caught, Kate kicked her in the stomach. Kate was very surprised by how soft the target was. This knocked her over, and she got up. After a quick (and rather dirty) hair yank and an attempted high eye jab, Kate ducked, and thought, "now's my chance!" She punched her belly several times. Every punch landing with strong force, Yelena's very soft belly didn't really have any defense for it. As Yelena was wincing in pain, Kate then slightly pushed her face to the left, and gave a very strong side-kick to the midsection. Her big toe actually entered Yelena's belly button, and she doubled over. Kate was now confident that she could win. She now knew that her belly was her weakness, just like Natasha. Yelena remembered what Kate sent, and tried to punch Kate in her solar plexus, only for Kate to deflect it with relative ease, and elbow her in the shoulder. After another sudden leg sweep to the back of her ankle, Kate then leaped knee first into Yelena's belly, causing Yelena to loudly groan in pain. Kate then grabbed Yelena's wrists, pinning them down, and trying to push her knee further into Yelena's stomach. Yelena, using her foot, quickly tapped out. Lila declared, "Kate wins!" Laura stopped filming, as Natasha ran over to Yelena. "Whoa, are you okay?" Yelena just silently lay down there, clutching at her belly while quietly wincing some more. While Nat was doing that, Kate was up and very happily victorious. Cooper high-fived her, while little Nate told her that she was so cool over there. Lila gave her a sisterly hug, and while admiring her very nice physique whispered, "Send me your workout plan." Kate happily nodded. Nate said, "Wanna celebrate with some chocolate milk? Or, strawberry if you like that more." Kate nodded. She then looked around, as all three Barton kids were staring at her. "Are you guys gonna keep looking at me, I feel weird just standing in the house half-naked." Lila said, "Right. Get changed, and then we'll have some of the milk." First, Nate told her, "Wait, Ka-Kate, I need to t-tell you a secret." She brought him in and closed the door, "What is it?" He told her, "You really beat up Auntie Yelena there. No offense, but I could see the way her tummy moved and shook every time you punched her. Like...a bean bag or something." Kate laughed, "Her tummy is very soft, and that means that she can't take tummy punches as well. I'll keep your secret, and you don't tell anyone what I said, okay?"

"Deal." They both went back outside. Cooper asked, "What'd he tell you?" Kate chuckled, "A secret's a secret." As they went to get the milk, Kate went back to check on Yelena. Yelena, very soft and childlike, said, "My tummy hurts." Kate apologized. She said, "How can someone leaner like you hit so hard? I thought the fat was supposed to protect me..." Kate explained, "for softer hits only. If I hit hard enough for someone with more belly fat, then it will hurt even more than it would for a person with less fat." Yelena sniffled, "Yeah." Nat helped her up. Yelena said, "I need to get changed back, I see the kids looking at me surprised." Kate then said, "Wait, we need to take some pictures. Lila!" Lila took some pictures of Kate in her bikini, as Cooper and Nate were watching, looking around to make sure no one was seeing them watch. She told Yelena to get in some. After one photo, she noticed how paunchy Yelena looked in a bikini next to Kate, and took a few more. Yelena and Kate still needed to get changed back, but as they were about to go in separate rooms, Yelena poked Kate in the eye and tried to yank her bra. Kate caught this, and with a quick, "what the hell", she quickly stopped Yelena and pushed her against the wall. Yelena guiltily put her arms up. This is what Kate wanted, as she quickly tied her bra on tighter, and then aggressively with her hand struck Yelena, with a finger stabbing into her belly button. This caused Yelena to almost tear up. Kate told her, "I know this is your house..." She attacked really hard again, striking her in the belly and her middle finger pushing more and more into her navel. "But these dirty moves need to stop. I won the fight that you challenged, now no more hitting. Promise?" Yelena, barely able to breathe with Kate's hand stabbing her in the stomach, simply nodded. Kate then pushed her hand even further, her fingers feeling like several pens stabbing into Yelena's gut, and said louder, "PROMISE?" Yelena, with tears down her face, nodded. Kate let go, as Yelena's belly dropped a little. Kate then said, "And good lord, fix that belly. It feels like a marshmallow, and no woman should have a belly overcoming her boobs." She slapped Yelena's belly, causing it to embarrassingly jiggle, and left. Natasha, not knowing what just happened, called Kate over. Kate asked, "What? I still need to get changed." Natasha told her to sit down at the table with Clint's kids. She asked, "Why do you want to get a pic of me half naked near Cooper and two kids? This is pretty weird, Nat..." Natasha replied, "It's funny, a hot girl like you in a bikini while these guys are fully dressed." She took a few pics, and then told Kate, "I would kill for that body. Those legs, those abs...they're hot." Kate, a bit weirded out now, got changed. When she returned, Natasha said, "Be honest. Were you holding back against me? You seemed like you were trying much harder against her." Kate admitted, "Yeah. I didn't want to go too hard on you." Nat said, "Maybe some time soon, we can have an actual match." Kate agreed, "Sounds like a plan." As Yelena entered her room, she closed the door. She took a few steps toward it, and then paused. She looked down, and realized that Kate was right. While her chest wasn't touching the door, her belly was. She said, "Oh no. That's not good. Also, it still hurts. That Kate really came after my poor tummy." Her belly had turned red from Kate's attacks. The inside of her navel was beginning to swell in particular. She cried a little more, and changed back. They started preparing for the movie, as Kate enjoyed some celebratory chocolate and strawberry milk with the Barton kids. They all watched Indiana Jones, and greatly enjoyed it. Even though Yelena fought through a really bad stomachache throughout the movie, she enjoyed it as well.
