He called her his only light in the darkness.

That's almost romantic! Almost.

Season 1, Episode 19: The Only Light in Darkness

The last thing he recalled was the flashing light and klaxon that had heralded the end. The power surge wave clearly struck with a force that had sent him reeling backwards into oblivion.

Fitz slammed his eyes shut against the bleak landscape. He could easily just assume that this was the end. Everything was endlessly dark although there were patterns in the inky darkness. Pools that ebbed and flowed in mathematical patterns that would otherwise had him wishing for his full array of gear to tease apart the mysteries. Instead, he just felt numb and cold.

Communications had been so bad that Fitz couldn't be sure if he was here alone or if Mack had managed to get clear.

Or any of the others.

After what felt like hours, his calves were aching in protest. He was so damned tired that he was resorting to mentally cursing the cosmos. Even talking was wearing him out that much faster, and he had to keep moving How did Jemma keep her mind going day after day and week after week in that dark abyss that was Maveth? She was alone for a time. But he didn't remember it being this wretchedly cold…

He shoved his hands into his jacket pockets, futilely hoping for some of the warmth to transfer. His fingertips grazed chilled metal.

Frantically, he dug it out of his pocket. He didn't mind the cold if meant some sign from Jemma.

It was all for naught. No signal. No call notifications.

But it was blessed light, if only for a moment, the electronic glow ringing around Jemma's picture like a halo. Fitz drew a heavy breath, wincing as he dragged his fingers across the screen. Her smiling face was as close to heaven as he might see in this endless hell.

Frowning, he powered it down. Jemma had to conserve power. Her phone had been the tool to save him. Given the opportunity, how could he wish to do more but return the favor.

He searched his mind, desperate to keep going somehow for her. He could only hope that she would reach out to him - to miss him - eventually. She could be mad at him all she liked just so long as he could make it back to her side.
