Shortly after you left with Loki, Steve came to the lab looking for you. You weren't there. He was positive that you said you were going to work in the lab today.

Bruce walks into the lab and puts a couple of folders on your desk. He looks up and notices Steve.

"Hey, are you looking for Lark?" He asks.

"Actually, yeah I am. Have you seen her today?" He checks his phone for any missed texts.

"I did but it was pretty early this morning. I haven't really seen her since. But I have been in and out most of the morning. Everything ok?" Bruce questions.

Steve nods a little. "Yeah everything's good. I was just coming to see if she had eaten breakfast. I know she usually forgets to when she's in the lab." He pats Bruce on the shoulder as he walks by him. "Thanks Bruce"

Bruce adjusts his glasses on his nose. "Don't mention it. If I see her I'll tell her you're looking for her."

Steve heads out in to the hallway and down to the training rooms. He checks the first one, it is empty, when he opens the second, he finds Nat and Clint but not you.

He stands and watches them spar for a couple of minutes. They break for a second and Steve walks over to them. "Have either of you seen Lark this morning?" He asks trying to push away a nagging feeling.

Nat and Clint both thought for a moment. Clint answers. "I saw her heading down the hallway to her lab, but it was just the back of her. I didn't even say "good morning."

Nat chimes in. "I shared the elevator down with her to the lab levels. She got off and I headed down to the garage. That was the last I've seen of her today. I'm sure she's just buried herself in her lab to get work done." Nat reassures Steve.

Steve sighs. "No I already tried there and Bruce hasn't seen her since early this morning either."

Nat looks at Clint and shrugs her shoulders. " Hey, I wouldn't worry. Maybe she took a break and grabbed something to eat. Have you tried the kitchen?"

Steve gives a little smile. "You're probably right. I'll go check the kitchen, she's probably there and we're just missing each other. I'l go check the kitchen, thanks. I'm going to let you guys get back to training."

Steve walks out of the room. Clint turns to Nat."Do you really believe that?"

"For both their sakes, I hope so." Nat says as she steps back on to the mats.

Steve goes up to the kitchen and doesn't find you there. He's starting to get concerned. If you left the tower you would have let him know, wouldn't you?

He has to know if you are ok. What if Thanos sent more henchmen for you?
"JARVIS, is Lark still in the tower?" He anxiously awaits the answer.

"No Captain Rogers, she is not. Is there anything else I can do for you?" The synthetic voice responds.

"Yes. Do you know when she left?" Steve's heart starts to quicken.

Yes, Captain Rogers. She left with Mr. Laufeyson almost two hours ago." He replies.

Steve goes over to the monitor on the wall. "JARVIS, Please play security footage of her exit."

He watches the screen as the video replay starts. He watches as you and Loki step out on to the balcony. He cringes a little inside when he sees you grab on to Loki so tightly but his fists ball up when he sees how Loki looks at you right before the Bifrost takes both of you to Asgard, he assumes.

His mind races as to why did you leave with Loki and did he take you to Asgard or somewhere else unknown. It's after 12o'clock now and you are not back. Steve makes himself something to eat but he can only stomach half of it.

He heads down to the park to go for a run and try to clear his head. He comes back about an hour later still with his head spinning with anger. He is doing his best to not be angry with you but it is so unlike you to do something like this.

He decided to go down to the gym and work out his frustration there. He's there using the punching bag for two hours when Clint walks by.
Clint stops in and approaches Steve. He can tell something is wrong by the force of his punches. "Hey man, what's going on? Everything Ok?" Clint asks.

Steve doesn't stop and keeps his eyes on the bag. "Yeah...No..Lark left with Loki hours ago."

Clint shifts a little, feeling like he's been here before. "That could be anything though. Maybe they went for lunch or something?" He says trying to down play your actions.

Steve's hits become harder. "They left in the Bifrost." Is all he says flatly.

Clint knows there is no calming him down with this one. "She'll be back." Is all he can say as he nods his head. He knows Steve just needs to be alone right now so he quietly steps out of the room.

The Bifrost opens on the balcony once again as you and Loki return. After you regain your focus again, you glance down at your watch. It's after 3 o'clock you've been gone for over five hours.

"Oh my god, I have to find Steve. He's got to be worried, I didn't leave a message or anything." You start to walk away but turn and look at Loki. "Thank you for everything, it was really amazing." You turn around leaving to find Steve.

You head to the elevator and push the button. You tell yourself that Steve probably didn't even realize you weren't in the lab. He rarely bothers you when you're down there.

As the elevator opens and you start to step in you come face to face with Clint.
"Hey Clint, do you know where Steve is by chance?"

He gives you an odd look. "Yeah as a matter of fact I do. He's in the gym working out some aggression. He's been looking for you."

"Great." Is all you mutter.

"Can I ask where you went with Loki this morning?" He asks genuinely.

"How did you know I was with Loki?" You didn't tell anyone you were leaving it was so last minute.

"Steve started to worry that maybe Thanos sent more henchmen after you. So he checked the security footage. He saw you leave with Loki through his light thingy. He's a little upset." He says stepping out as the elevator door opens.

"I didn't mean to scare him. I thought it would be just a quick lunch." You say to Clint but more to yourself as the door closed.

"Great." You think to yourself.

"He doesn't own us, you know that right? We don't need to report our every move to him" You can hear Hyde say in your head.

To a point she's right but you also know that your whereabouts are important to Steve right now. You never meant to worry him. But we don't need to ask anyones permission to go somewhere especially with the God. They worry about my safety right now, they just care. We are strong enough by ourselves, we proved that yesterday. We stopped the Gods and the Green One without breaking a sweat. I know that but when you love someone you give them that courtesy. He just doesn't trust us with the God that's all. He's jealous and you know it. Maybe you're right but it's not like he's not justified. He trusts me, he just doesn't have the same trust in Loki. Does he really trust us though...hmmm?

You've reached the door to the gym, you can hear Steve before you even enter the room. You slowly open the door and walk in.

You take a deep breath as you walk up to him. "Hi." Is all you can say to him

He doesn't look away from the bag. "Where were you?" He keeps hitting the bag.

"Loki took me to Asgard for lunch. I didn't mean to be gone so long." You were nervous and frustrated at the same time.

Steve's pace picks up as he listens to you. "You could have told someone." His punches come even faster and harder now.

"I'm sorry Steve. I didn't think...." But you are cut off by Steve.

"That's right you didn't think Lark!" He punches the bag one last time knocking it across the room.

With that and the tone of his voice you snap. Your eyes burn a darker blue. "I'm not a GOD DAMN CHILD, STEVE!"

You push his chest and send him back a step or two. He looks up at you still angry and takes a step toward you. "I didn't say that!"

You narrow your eyes as he looks at you. You tilt your head a little. "You don't trust me, do you?" You say accusingly as you take a step closer to him.

"Of course I trust you. I just don't trust Loki alone with you." He says not breaking eye contact.

You shove him again. "Which means you don't trust me to stop him if he tries something."

You can see Steve reaching his limits. "GOD DAMN IT LARK!" He yells at you.

Your temper flares and your eyes get darker. You take and push Steve back against the wall, hitting it with a thud. "Don't you ever yell at me again!"

Something shifts inside Steve and you can see it in his eyes. He grabs your shoulders, turning you and slamming your back against the wall. " I WAS WORRIED ABOUT YOU!" He yells as you stare into his eyes.

Suddenly his lips are on yours. Aggressively kissing you, a mixture of teeth and tongue. You moan into it. You turn and flip him back against the wall, you forearm over his throat.
"I said don't ever yell at me."
Steve places a hand on your arm. You think he's going to try and fight you, but he pushes it there. Taking his other hand and grabbing you by the hair, he pulls you into another kiss. This does something to you and you need more.

You rip at his shirt, needing to feel his skin. He lets out a low groan almost a growl before he rips your shirt off. His hands are needy, roaming all over you body. He slides his hands down to your waist, deftly undoes your pants and slides them down your legs. You take your free hand and slide it down below his waist, palming him through his sweats.

You grab him by his shoulders, turning him and throwing him down on to the mat. You stand over him as he claws at your calves. You look up for a moment and look around the room. With a flick of you hand, the door to the gym is closed and locked.

Steve pulls at your legs bringing you down to straddle him on the floor. You look up once again, looking at the security camera on the wall. With a snap of your fingers, you've disabled the feed.

Steve sits up, his arms reaching around you, unclasping your bra. It feels like your bodies are on fire. You push him back down, his eyes dark with a new found lust, your eyes burning a dark blue.

"Do it again! He likes it rough, he just won't admit it." You hear her say in your head.

You start to grind against him needing some friction. You reach down and wrap your hand around Steve's throat and squeeze. His grip on your thighs tightens, he lets out a groan as he pushes his hips up, needing to feel more of you.

" Well, well, well...Captain Perfect has a kink. I would have never guessed. Us it." Hyde exclaims in your head.

Steve can't take it any longer. He tosses you to the side and sheds his sweats. You get up on your knees but he pushes you back down. He comes up behind you grabbing you forcefully around the waist, entering you. He's rough with you like never before and you like it.

He grabs you by the neck pulling you up against his chest never slowing his rough pace. His hand wrapped around your neck as he bites your shoulder. Your lift your hands behind you, grabbing his hair, pulling on it hard.

He easily rolls you to the ground and is on top of you again. You look up into his eyes as he resumes his unrelenting pace. He can feel you reaching your peak, as you do a devious grin comes over his face. You can tell he is close to his also. You reach up with both hands and wrap them around his neck. As you tighten your grip, you wrap your legs around him pulling him in closer. You smile as you feel his release and see him come undone in your hands.

He rides his high out and collapses on the floor next to you. Both of you panting trying to catch your breath, hearts still racing.

Finally Steve catches his breath. "I..I didn't hurt you did I?"

"Exactly the opposite." Are all the words you can seem to form.

"I don't know where that came from. It was...." He shyly says before you cut him off.

"Amazing!" You say as you roll over and give him a kiss.

"Yeah, that about covers it." He says with a grin before he kisses you again.
