Steve screamed, sitting straight up in bed. Bucky was beside him immediately, pulling the small man into his arms and rubbing his back soothingly. "I'm here, Stevie. It's okay."

The blond sniffled. "You and Ma were dead. And Daisy, too. And it was my fault. I got sick, and you took care of me, and then it spread and killed you."

"Nope. Sorry, Stevie. It's impossible, I've got the strongest immune system on the planet, after hangin' around with you for fifteen somethin' years." He poked the blond's ribs. "Besides, a little cold never killed anybody."

"It almost killed me," Steve pointed out. "Remember last January?"

"It was one time, Stevie. And you're still breathin', aren't you?"

"Barely."

Bucky sighed. "Fine, your asthma is pretty bad. But I promise I'm not gonna die because of you."

"Fine." Steve burrowed into Bucky's side. "Can you sing for me?"

"Aw." Bucky pulled the covers over them, and sang to both of them softly."Well, I've never been a man of many words. And there's nothing I can say that you haven't heard."

Steve quietly sang the harmony, his hands sneaking up the brunet's shirt. "But I’ll sing you love songs till the day I die."

"The way I'm feeling, I can't keep it inside."

Bucky smiled. "I’ll sing a sweet serenaded whenever you're feeling sad. And a lullaby each night before you go to bed. I'll sing to you for the rest of my life. The way I'm feeling, I can't keep it inside."

Steve snorted softly into the brunet's neck. Bucky sang the last line to himself, beginning to drift to sleep. "No, I can't keep it inside."

Yes, that is Benedict Cumberbatch. Yes, that is one of the only reasons I used this song.
