This is the conversation Clint and Natasha had when she first told him she was pregnant.

For the first time in his life Clint couldn't think of anything to say, his jaw slack with shock, he did nothing but stare at Natasha; waiting for his brain to comprehend what she'd told him.

Finally finding himself, he took her hands and pulled her from the floor, leading her into the bedroom, they sat together on her bed.
Clint didn't take his eyes off her the entire time, Natasha avoided his gaze with expert stubbornness.

Eventually he broke the expansive silence which had fallen over them;

"What do you... What do you want to do?"

She didn't respond, she couldn't respond. She was still in shock; as far as she was aware this couldn't happen, it was impossible...

She had been feeling ill for weeks; she was tired and ached everywhere. She only went to the doctors after Steve expressed his concerns about her to Coulson; who'd practically dragged her down to medical.

The doctors on SHIELD's staff were familiar with her medical history and seemed equally shocked to learn of her condition. They'd wanted to run some tests, but Natasha had refused and fled back to the tower, seeking comfort in the one person she trusted above all others.
She knew what she wanted to do, but she was scared. She didn't know how to admit it to Clint, not sure if he felt the same.

The silence stretched out in front of them, it wasn't until a tear silently fell down Natasha's cheek did Clint speak again.

"Natasha, I'm here. I'm always here for you. Whatever you want..."

It unnerved him that he didn't know how she was feeling, he always knew how she felt, what she was thinking, and how to make her feel better. But this was all completely new and unexpected.

The tears continued to fall down Natasha's face, but eventually she turned to face him, she saw reassurance in his eyes. His arms wrapped round her and pulled her towards him, he kissed her gently on the cheek and waited patiently.

"I didn't think this could ever... I was sure I couldn't..."

"Tasha, it's okay"

"What do we do?"

She was sat between his legs now, leaning her back on his chest and her head on his shoulder. She never felt safer than when she was with him. His hands rested over her abdomen, something he had done hundreds of times before, but a gesture which took on a new meaning now.

"I always wanted to be a dad" he admitted, almost a whisper.

Natasha smiled at him, she felt instantly better knowing that he wanted it too. That she wasn't alone. She kissed his jaw, turning in his hold to wrap her arms around him in return. She exhaled deeply, a calming breath to steady herself before she spoke again;

"We're really going to do this? We're going to have a baby?"

"We're going to have a baby" Clint responded, a grin on his face, excitement gleaming in his eyes.
