Doctor who: Prisoners of Time

Prologue

America 2018,
Adrien panted heavily as he chucked his rusty shovel deep in the rock hard ground in the middle of the vast junk yard, he was overwhelmed with the amount of scraps he had to clear before midnight, but he had to do it even though his health didn't allow it ; He is the kind of chap you'd expect to be sitting on his rocking chair sipping hot tea in front of a warm fireplace, with his children and grandchildren all around him, after all he is 61.
But instead he is stuck in a significantly slow and budget-less work at the scrapyard, he hasn't had the chance to go out and meet new people, He was too reckless and naive when he lost his newlywed wife,  she had run off with a wealthy man and was never heard of again, he had refused any contact with the outside world, instead he locked himself in his study where he destroyed everything he ever loved, he couldn't bare the sight of anything from his past, it was simply too painful; so he collected all his life savings and rented a flat far from London.
Ever Since then everything just seemed to go wrong for him.
But the past was a door he kept shut, but that didn't stop him from crying himself to sleep every night, he was once a bright young man filled with hope and potential, he would've never imagined himself in this position; an old man living alone in a crappy rented flat right next to a scrapyard where he worked for minimum wage, he was meant to go places, he always had the potential to travel the world, to make a figure of himself', but all his potential and dreams went down in flames because he fell in love with the wrong person.
His physics degree had been sitting on the top shelf of his closet collecting dust for the past 45 years, he was meant to be out there exploring the world!, but instead he spends his time digging scrap 9 feet underground for his monthly pay of 21 quid, which barely payed the rent.
Rain began to fall and the once calm night sky got clouded up, wind blew heavily, it was a cold winters night, Adrien dug up another pile of damp and rusty scraps as he dumped it at the big pile of junk; mounted six feet behind him, was the remains of abandoned cars and such' he breathed in deeply and let out a heavy huff, he was just about to take out another pile of scraps when he heard a silent rustle In one of the huge mountains of junk.
"Hello?" He yelled, his voice echoing around him, *rustle*.
"Stop messin' around or you'll be in deep trouble_" 
He was interrupted by another rustling noise from behind him this time,
"Come out! I'm armed!"
He aimed his worn out shovel as protection, this time he heard foot steps coming from the far end of the field,
"That's it, I'm callin' the cops!" He warned, he shivered as the cold wind blew harder.
He grabbed his phone from the muddy ground, but before he could dial; a metallic arm pressed hard on his weak shoulders, he fell to his knees', blood seeped from his nose and eyes as he screamed in agony.
"You will be deleted-" a robotic voice demanded from behind him,
"Delete-Delete-Delete"
His screams echoed across the wide junk area as he slowly drifted into darkness...
