A/N: Written before I saw the finale, obviously. Just one of the many Fitzsimmons in the box fics out there, nothing really that original just my take on it. Be warned character death.
Spoilers: for anything up to and including 1x21 Ragtag.

Her eyes had started drooping. It was getting harder and harder to stay awake. All she knew was that she couldn't fall asleep. But standing up and walking around to clear the cobwebs took too much effort and wasted what little oxygen was left in there. She let her head rest on her knees, it would be for only a minute. She was just so tired, so exhausted. She could feel it taking hold of her skeleton, the exhaustion, crawling inside of it and taking habitat like a cold wind inside a too thin summer jacket, making all of her 206 bones scream for sleep.
She wasn't stupid, she knew she couldn't fight it forever. The oxygen deprivation was going to kill her - she forced opened her eyes and looked to her side - kill them, sooner rather than later. Fitz was still awake, sitting mirroring her position, head resting on his knees that were pressed against his chest. Too exhausted to speak his bright blue orbs searched her hazel ones, worried. She had hit her head in the fall which was likely why she felt a bit more tired than him at the moment, still she thought he had it worse, his left arm was definitely broken in more than one place, she'd tried her best to make a splint but she could do nothing about the pain.
At least she wasn't going to die alone. Fitz was here right beside her. As always. Not that she wanted either of them to die. But at this point in time she had no control whatsoever over their shared faith. It seemed inevitable. Choking to death on carbon dioxide didn't sound very appealing or very pleasant, but it was really more like slowly being lolled into a peaceful sleep, so no suffering there at least.
Nobody was going to come to their rescue. So she might as well surrender to the circumstances, accept the situation, throw in the towel and just let it all go. With one last look at Fitz she forced the muscles in her cheeks to make her mouth smile the smallest of smiles before she closed her eyes for good, knowing she wouldn't have the strength to open them again. And the last thing she heard before she drifted off into the black nothingness was the sound of Fitz' hoarse oxygen deprived voice whispering her name: "Jemma." The pleading implications in it were evident - Don't go! Don't leave me here alone! You have to fix this!
But it was too late, there was no way she would be able to fix anything anymore, not this time.
A/N: Didn't have a chance to upload before the awesome finale, so I know most of this is totally inaccurate now, but I decided to post it anyway, I hope it's still semi enjoyable.
