It isn't every day the Avengers are called in to save nearly extinct species, even if there are only four of them left.

But this time it's different. Hydra has found some sort of militaristic opportunity in them.

So now, the Avengers are officially zookeepers.

"Really? We are here to babysit rhinos?"

"Concentrate, Clint. We cannot let Hydra win."

"Yeah, relax." Widow murmurs, running her hand across his back.

Steve's eyes nearly bulge out of his head, but he quickly composes himself and walks away.

"Nat." Clint hisses. "Do you want to get me killed?"

"Sorry." She laughs, burying her head in his shoulder.

Later, when she feeds the baby rhino with that mothering nature hidden deep within her, Steve's heart melts.

It's not just him, her cooing has the others gaping.

It was that day he decided to take her as his.

They have their honeymoon in Madagascar, but only Clint understands.
