Natasha was still in a induced coma. They gave Lance a beating, so that scared him away for a while. Steve couldn't believe it.

Steve sat by her bedside each night and prayed to God that she would wake up and be alright.

But there was no sign of hope at all. All you could hear was the sound of her heart monitor, that would occasionally go down and then bounce back up.

And Steve couldn't bare it anymore. So one day he left the hospital, with a note that he tucked underneath her pillow.
He kissed her head sweetly and walked through that door and didn't look back. He went to the tower and packed a bag. He didn't take his motorcycle either because the Avengers could track him down easily. And it was the peek of night so no-one noticed. Other than one person.

"Steve? Where the hell are you going?" Tony asked.

"Away. Tell Nat and the team, I'n sorry."

"I doubt that. We just got a call from the hospital, she's slowly making progress."

"Tony, I just can't. It's hard you know. I saw what happened I was there. I saw the car coming, never knew that it was going to hit her. Can't you see? This is my fault. I should be in that bed, not her. I should be the one being punished, not her. This is all my fault, can't you see?"

"What about us? Huh? What about Clint? They were the closes out of all of us put together. He's sobbing his heart away, praying that his best friends is going to be ok. She a aunt, she's a sister, and your really thinking of running away? From what?" Tony asked.

"I'm just afraid! Can't a guy be afraid? The last time I was so close to someone, I ended up in the ice for 70 years. Now I come out and see that my true love is dead, I carried her coffin remember? My best friend is now working for the opposing threat, and your asking why I'm running? There's your answer, I'm just fucking scared." Steve said with a tear drop in his eye.

"Steve, I understand. But not now. It's gonna break her when she wakes up. You really can't." Tony said whilst fulling tears streaming down his face.

"What choice, do I have?" He whispered.

He opened the door and walked out and that indeed was the mystery of Captain America.
