The morning of the mission

After an eventful night, you and Bucky are cuddling in bed when Tony knocks for you to both come down for your mission brief. 'Come on lovebirds, got a good one for you today. You're gonna love it.' He shouts as he walks away.

'Ugh can't we just stay here? I love morning cuddles with you.' You sigh and get up, put your hair into a ponytail to keep it out the way and pick out some sweats, you're sure you'll need to get changed before leaving anyway so it doesn't matter. 'Come on James, mission time! I'll meet you downstairs, don't forget to lube up that arm, don't want a repeat of the last time.' You throw some clothes at him, kiss him quickly and walk out to head towards where everyone else is congregated. 'Hey guys, Bucky is just getting changed. He'll be down in a minute.' You say happily to everyone else.

'Ok cool, we can wait a minute. You might wanna go get changed yourself though kid, this is your favourite type of mission. One you get to dress up and flirt for. Ah good for you to finally join us Barnes.' Tony says as Bucky walks up behind you and wraps his arms around you. 'Ok now we're all here let's make a start. This' he pulls up a picture of a man you've definitely seen before 'is Jeffrey Burns. Basically, a nobody that ended up the owner of his best friends pretty successful art dealership after his suspicious death. Since then, we've heard some pretty dicey reports coming from there, fake art, staff going missing and turning up with no memory of what happened, that kinda thing. Our mission is to find out what happened and make sure the police have the right guy to arrest. He knows who all of us are so we've gotta do this carefully. Mia, he won't know you're one of us, your job is to find him and flirt with him. Talk him into telling you everything, use all your skills and make sure we have the right guy, make sure he doesn't leave your sight. Scott, you're there as her bodyguard. You'll be on her at all times and if anything looks weird let us know.' He turns to everyone else. 'The rest of us will be sneaking into the lower floors of his building and finding evidence our way. Except Bucky, you will be stood outside alerting us to ANYTHING suspicious that goes on. Got that? If someone outside sneezes looking at the door you let us know. We can't be too careful with this one. This guy is known to be violent, that's the reason the police wants the Avengers to help them out. Ok is everybody clear on what they need to do?' You all nod at Tony. 'Ok cool. Kid, go put on your nicest dress, party's at lunch.'

You nod and run off to find your favourite lunch date dress, a glitzy bodycon thigh high number with spaghetti straps. You curl your hair and make sure your makeup is on point.

'Wow you look hot! Bucky is one lucky guy!' Steve exclaims as he walks in to talk to you about the mission. 'How are you feeling? You looked worried down there. What's up?' he asks you worriedly. As soon as Tony mentioned the target you got worried, but you tried not to let anybody see.

You laugh slightly. 'Well… That guy is actually my ex. From when I was a teenager. He's a little older than me, he's a nice guy don't worry, I'm not in any danger. We just drifted apart.' Steve looks at you wondering when you're going to tell what you're worried about. 'Thing is, towards the end things got... Weird. He started drinking. A lot. And he never touched me, he always had major respect for women and never hurt them at all, but he did start to get violent, especially towards Andrew. That was the best friend Tony mentioned. I'm worried he'll figure out what's going on and get angry and do something crazy. I don't know Steve, I just worry.'

'Oh wow. Well, it'll be ok, you'll have Scott with you and he'll never let anything happen to his baby sister. I'm guessing Scott doesn't know this guy?' you shake your head 'Ok so just don't tell him. You'll do fine, this isn't your first mission and you've bossed them all so far! It's gonna go great.'

You smile at Steve and hug him to say thanks. 'Come on then, let get going, Tony said be downstairs at 11. I'm fine don't worry. Just need to see Bucky, he calms me down.' You both head downstairs, everybody stares at you as you sit on the sofa. 'What? I dress up nice sometimes.' You say laughing slightly. Everyone is all suited up except for you.

'Holy shit doll you look amazing! I almost don't wanna let you go.' Bucky comes to sit next to you and whispers to you 'how are you feeling sweetheart? I noticed you were a little nervous earlier, wanna talk about it?' You shake your head and let him know you'll explain after, you just wanna get this done. 'Ok doll, well you'll crush this looking like that!' Tony stands up and gestures for you all to get going.

A few hours later

'Wow that was great! You did such a good job Mia; how did you get him to talk?' Nat asks you. 'It's like you knew him already. Wait, did you? Is he that ex you were telling me about last week?' You glance at Nat to let her know to be quiet 'Oh sorry, guess you and Bucky need to talk about that then.' She hugs you and walks away.

Tony walks up to you and gives you a huge high five. 'You did so good!' he leans in to whisper in your ear. 'Next time please tell me if our target is an ex-boyfriend of yours. I don't want you getting hurt, Bucky would murder me if I let that happen.'

'Sorry Tony, I didn't want Bucky to know until I'd had a chance to talk to him, I was gonna talk before we left but he was already downstairs. I'll make sure to let you know next time!' You run over to your boyfriend and hug him. 'Baby that went so well! I'm so proud of my bodyguard boyfriend! I love you!' You start to feel a little dizzy, which he notices so holds tighter onto you.

'Whoa you ok doll? What's wrong?' He asks, worry in his eyes.

'I'm fine, probably just hungry. I haven't eaten much today. I couldn't eat anything at the lunch because I was so nervous and same for breakfast.' You start to move to the sofa to sit down but get overtaken by a wave of nausea, which causes you to run to the bathroom as quick as you can, Bucky following you.

He holds your hair back and rubs your back as you throw up. 'Oh, doll what's wrong? You were fine earlier.' A look of realisation comes across his face. 'Um, Mia, could you be pregnant?'
