Zombie AU
Kitty was running. She couldn't remember the last time she hadn't been running from something – her marriage, her husband, her past – but right now she was actually running. The zombies chasing her weren't particularly fast, but they were everywhere. She stopped to catch her breath in a thankfully deserted alley, but as her breath slowed, she heard a muffled sobbing coming from behind the large dustbin that took up most of the width of the alley. Kitty approached cautiously, her nurse's instincts overtaking her sense of danger. On the other side of the bin, a dark-haired young man, clearly ravaged by zombies, lay in the lap of another young man, who was crying into the first man's hair.
As Kitty's footsteps neared, the crying man looked up abruptly. "He's dying," the man choked out, his tears making his already thick Scottish accent almost unintelligible. "I'm a doctor...so is he...but I can't...I don't know how to fix this!" Despair shone out of desperately blue eyes as Kitty sat down beside the man, determined to provide at least some comfort.
"What's his name?" Kitty asked softly.
"Miles," he whispered, and Miles somehow managed to smile softly at the sound of his name. Kitty took the inconsolable doctor's hand as he softly kissed his friend's brow and shakily closed Miles' eyes as the life left him.
Moments passed with no sound other than the young man's weeping. Then with a Herculean effort, he took a deep breath, stood up, and held out his hand to Kitty.
"We should go," he sighed.
Kitty nodded and accepted the man's hand.
"I'm Tom."
"Kitty."
Tom nodded and they walked from the alley in silence, still hand in hand.
