You don't have to wait long.

You're home for barely a week before it happens.

You've spent your days talking baby names and paint colours and playing with Theo; you can't remember being this relaxed in your entire life.

Your wife does everything she can to keep you that way; she remembers your pill times and makes sure you eat properly and takes you to your appointments.

She never leaves your side; you end up in a rocking chair on the training floor at Stark Tower so she can keep an eye on you and train Skye at the same time.

You watch as your son gets passed around, taking to each person as easily as the last; you haven't laughed so hard in a long time when you witness Thor feeding him.

You're not sure who was messier by the end of it.

The people you are surrounded by have become your family, not just your team or your agents; the rare moments your wife lets her prodigy take a break sees the younger girl with the biochemist grinning and trying to hide it.

You shake your head and grant a kiss.

You whisper to her when she crouches next to you and skims the nursery design you were looking at; you're pretty sure the two of you started something.

It turns out that Pepper is pregnant too; your wife has nicknamed the unborn child Iron Baby and calls Skye back onto the training mats after a round of congratulations and celebratory hugs.

You spend your afternoon comparing notes on your partners; Stark is terrified even though he's not showing it and you explain about your wife's fear when you were pregnant with Theo.

You've never contemplated your last moments.

You've always take it one day at time; something you've learnt to do as an Agent of SHIELD.

You're Maria Hill and you don't realise that this Thursday evening in the Tower could be your last.

Not until Pepper comments that you're awfully pale and your nose has started bleeding.

You hear her call for your wife; you can see her face drop as she runs to you.

That's the last thing you see before you pass out.
