Right or Wrong? {complete}

Just a mission

                     Natasha and Steve (POV)
Steve:
This was wrong. I couldn't keep thinking about Natasha this way. I couldn't keep flirting with Natasha like this. She loves Bruce and has no idea where he is. And he loves her. I felt like I was betraying my best friend. I was going to make this right and I knew just how to do it.

Natasha:

It's Tuesday. The day Steve and I train the soon to be S.H.E.I.L.D agents. Practice usually runs pretty smoothly. It's nothing but a mini workout for Steve and I, thanks to variations of the serum. We have set up a routine. We get there ten minutes before practice starts and plan out what we will do.

Afterwards Steve grabs his bag and walks out behind the soon to be agents. On his way out he always goodbyes me with a "Romanoff." I've memorized his actions and I know what to expect every day.
At least on a normal day.

But today is not a normal day. Today instead of following the trainees he walks right up to me.
"You need something Rogers?" I ask, narrowing my eyes.

"Actually I wanted to propose something to you." I raise and arched eyebrow at him. Telling him to go on.

"I want to help you find the hulk. Find Bruce."

I felt my mouth open in shock. I didn't know what to make of his proposal.
"What?" I ask, eyes wide.
Why now?
Why him?

"Nat you deserve to be happy. He makes you happy and I want to find him."
I look up into his pure blue eyes, searching them for answers. God you care to much about me, Rogers.

"You know he has disappeared from every S.H.E.I.L.D radar. And I think S.H.E.I.L.D wants to find him more than we do." I play along, treading
lightly.

"Well I'm sure with are resources we could find him." He counters, encouragingly.
"Steve you really don't need to do that." I conclude, hoping to end this discussion.

"Yes I do." He orders in a serious and almost desperate tone.
"Why?" I shoot at him.

He swallows hard before continuing. " Because-" He hesitates. " Because I see the way you look at him. You used to look at me that way." He says with more confidence. I notice how his blue eyes fog over.

Most noticeable is the unknown pain in my chest. Damn that hurt. I didn't want to hurt him. I want to say something but his last words leave a sting that leaves me speechless.

"You should be with him. I'll go now but think about it okay." He leaves me with a hurt look on his face.
He turns his back to me and starts for the door.

Before I know what is happening I'm talking. "It's a mission!" I call out, the words echoing off the metal walls. The air seems thick, suffocating.

Shit, what just happened. Did I actually blow my cover for the first time? I've been compromised.
I pray that he didn't hear me. But he was well within ear shot and my loud words would be impossible to miss. My fear came true when he slowly turned around.
"What was that?" He asked.
I search my brain for excuses. I'm usually so good at this.
"Nothing just forget it." I lean down and start collecting my things. But, he's not having it.

"What did you say Romanoff?" He says this time more serious maybe angry. Maybe he senses the fear in my eyes because he seems to calm down.

"Talk to me Nat. Please." He looks at me with pleading eyes. I know he will figure it out one way or another. Now he knows. I might as well tell him the full story. I look up at him and those damn hurt looking eyes. I can't help it. I can't stop myself.

"Bruce. The hulk." I pause trying to put the pieces together for him.
"He's-" Only Steve could make me speechless. I finish by saying "Just a mission" as if it's nothing.

"So you and him. You don't... uh." I could tell Steve was embarrassed.

"No I don't love him Rogers." He's speechless for a moment. Silence looming over us.

"Wow." He says shocked.
"And no Fury hasn't told me what to do now that the hulk went on vacation. So I need to you to keep quite until I talk to him." I say to Steve who is still 3 feet away.

He looks mad. "Listen I know it's wrong..." I say trying to calm him down but I am stopped when he starts walking towards me. Just when I think he's going to slam me against the wall and yell in my face he actually puts a hand on my cheek. He looks straight into my eyes. And then...
