A single day. For the rest of eternity
"You sure this will work with humans, right?"
"Of course, of course" the man in the lab coat said, though a little uncertainly. This was probably due to the fact the they were stood on top of he tallest tower in the city and they were about to test the newest modern form of travel. Teleportation.
"Keep looking at you destination. Now" the man in white ordered.
Alex blinked, the image of his destination imprinted into his mind.
"Where did you come from? Mind where your going" a woman's voice said. A shoulder knocking into Alex's as he stumbled into existence on a wide, car filled street.
"I'm sorry madam" he started "I didn't see you there"
"It's quite alright" she smiled, their eyes met. "I.... I'm Sarah"
"Alex" he said, tipping his brown fedora hat.
"Are you okay?" Said Jacob, who abandoned his white coat for his more formal suit.
"I'm fine, my breather is just a bit faulty today" he explained, thinking to the times before the air pollution had forced humans to carry air around with them. Though it was of little inconvenience, as they could carry air around their bodies with little effort thanks to the breather, a device which held in place fresh air around its holder.
"When did you last refill it?"
"This morning" Alex stated.
"Let me have a look"
"I'm late!" Alex jumped up, Jacob had just finished fixing his breather.
"Late for what?"
"A date!" And he ran out of the room.
Rain poured down from above. The basket he held was damp. The shelter he used was leaking. The wind he felt was deafening. But the sight he saw, the sight he saw made him smile like the rain had stopped and the sun was shinning.
"Hi" he said.
"Hi" Sarah replied, smiling.
"I don't think a picnic would be quite as nice in this weather."
"No, I don't think so" she laughed "would you like to get some coffee?"
The coffee shop was empty except for two customers, who sat side by side, leaning against the window. One with a fine suit, the other with a bright yellow dress.
"I haven't had a picnic since I was a little girl"
"Nor have I" Alex agreed "this day could have been perfect."
"And it still can be" she grinned, and pulled him out the shop by his hand"
"Where were you yesterday?" Jacob inquired.
"I was out"
"Out? It was pouring down, you must have gotten soaked."
"No, no. We went to have a meal at Antoine's" Alex said, smiling reminiscently.
"Antoine's? But that place never let's anyone in without booking months in advance."
"Not when your date's brother is Antoine himself."
"Agghhhh" Jacob flew across the room, crashing into the soft foam wall.
"Still not working is it?" Asked Alex, though he knew the answer.
"No." Jacob scowled. "It needs a better source of power"
"We still have one of the old power cells around." Alex said questioningly. "You know, one of the ones that almost blew up the building when hooked it up to the mains to charge."
"Oh yes." A devilish look in his eye "lets get that out and give it a whirl."
"It's too powerful!" Jacob shouted over the sound of the device. "There's to much energy!"
The device had raised itself up, creating a sphere of blue-ish light around it. Things around the room began to get sucked into it, and with each absorption, the sphere grew larger.
"Get out of there!" Alex yelled through the glass wall he was stood behind, attempting to control the device using various machines and computers.
"What happened?" Jacob entered the control room.
"I don't know, it just sucked up the power and started forming an orb"
The orb has grown and smashing down the walls of its confinements.
"It's going to destroy everything, it can't be stopped!" Jacob shouted over the roar of the wind being sucking into the vortex that was the orb. The crashing sound of metal echoed in the ears of both men.
"I'm running out of air Alex"
"What? But there's no time to refuel, we need to stop the sphere!"
"I know" and he walked towards Alex and ripped his breather off of his chest, giving his friend his last living breath.
"No!" Alex shouted. But he knew better than to let his newly replenished stock of air go to waste, he had to save the world.
"Alex? Alex? Where are you?" Sarah's voice echoed in the room, surrounded by the sound of the crushing vortex.
"Sarah? What are you doing here? You have to go, the buildings coming down"
"What is that thing?" She looked worried.
And it was in that moment that he decided.
"Follow me" he said, and they ran up the stairs towards the roof.
They sat, just the two of them, as they had often done, him with his fedora hat, her with her flowing yellow dress, on the edge of a cliff.
He raised a glass.
"A toast" he said.
"To what?" She smiled, biting the head of a strawberry and raising her glass.
He put the picnic back away, and looked up at the stars.
"I don't understand what happened" she said.
"Today's the last" he answered simply, to save her from knowing.
"The last what?" Sarah whispered, her eyes shimmering.
"Everything" and he looked off into the sky and saw the blue planet that had always been their home, sitting in the distance, waiting.
"I don't under...." She began.
"Shhhhh" he placed his hand on hers.
A blue wave of light and energy burst from the earth in the sky, and traveled outward in all directions ending everything everywhere.
Even the moon.
That was the last day of existence, and only one person could have stopped it. If only he had had more air. But he couldn't let her die too. Even if it meant the end of the world.
