Two times Jack left Ianto, and one time Ianto left Jack
Twice – Jack
They were busy bickering, investigating the latest supernatural occurrence of the moment – which turned out to be a significant event to the whole world. Children, all stopping still, silent and staring at nothing until their voices rang out in synchronicity. WE. ARE. COMING. Hundreds of thousands of children, of all ages, speaking the same words at the same time, sounding hauntingly eerie.
Ianto lost the company vehicle on a rough council estate, even though it was fully equip to put off any would-be criminals from stealing it.
Jack insulted his daughter with his infrequent visit that coincided with the latest world disaster.
They gathered back at the Hub, Ianto meekly shy at his gross vehicular error. Jack still thoughtful of the conversation stemming from his recent conversation with his daughter.
Gwen, the only woman inhabiting the Hub these days had her hand on the body scanner in the autopsy bay. Her gaze fixed onto the wall above her that projected a slightly distorted image of her body and a small red spot alive in her pelvis.
Congratulations and jubilations were bounced around the red brick walls. So excited, Jack placed his hand over Gwen's, still on the scanner.
A bomb. He had a bomb in his stomach. He was immortal, yes, but he could never survive a blast from within that would tear his internal organs, muscle tissue and bone to shreds. Twist and contort the torn pieces of flesh as the blast plastered his organic matter to bricks and open space.
"There's a bomb, there's a bomb inside your stomach!" said Ianto, pointing out the obvious.
Jack forced Gwen to leave for the sake of herself and her unborn child.
"Get out!"
"No!" said Gwen fearing for Jack's safety, not knowing what to do for the best.
"Both of you," Jack demanded of his colleagues.
"No!" repeated Gwen for the second time.
"Right now!" said Jack raising his voice, as if shouting would make them move.
" It has a blast radius of one mile!" Ianto still intent on his computer screen, attempting to stop the inevitable.
" Right now! Get out!" Jack's last ditch attempt before using physical force.
" Look there must be something we can do. Look we can stop it. We can fix this ok, we can rip it out of you." Said Gwen trying to rationalist what was going on.
"I'm telling you. Get out!"
"It's active. Two minutes!"
"I can't just run, Jack."
" You're pregnant," pointing out the obvious, getting Gwen to realise that the red spot lodged in her pelvis was real.
Gwen stared directly into Jack's eyes, trying to decide exactly what she should do. Finally making a decision she stepped away from Jack, running out the door as fast as her legs would go.
Ianto refused to leave. He secured the building, as Gwen departed, so the city would stand a chance at being safe. Ianto desperately wanted to stay and help, but the blast would obliterate him too, and Jack refused to let that happen.
" Ianto, you're going to get locked inside. Ianto! Then you…"
Jack grabbed Ianto from behind, gripping his arms in a tight grip so he couldn't escape. Hauling him across the Hub, down concrete steps Jack gave Ianto no choice but to move, or be dragged.
"There must be a way to override the mechanism," shouted Ianto loudly so he could be heard over the noise of the lockdown in progress.
"For God's sake, get out!"
"There'll be nothing left of you!" Ianto cried out, distraught that this could be the last time he might see Jack.
"I can survive anything," Jack said noisily.
Pushing and shoving and cajoling Ianto towards the invisible lift he swung Ianto around to face him, seizing him roughly, pulling him close and kissing him deeply. That one kiss communicating all his thoughts and feelings, despair, love, fear of this last death.
Panicking at the lack of time Ianto had left to escape, Jack let Ianto go, stepped away and hit a button on his wrist, sending the invisible lift up towards the heavens. They kept eye contact all the way up.
"I'll come back. I always do," Jack promised Ianto, who was too far away to hear him, and more so himself. Thirty seconds after Ianto disappeared from view the world exploded. Jack felt himself rip apart with such horrific pain, as the bomb counted off its final second before he felt nothing at all.
