He is not the same man he once knew, because that Ianto Jones died in his arms 10 years ago this was not the same man. When the Doctor took him back to Earth to show him this place he had no idea how this would change his life. The Doctor walked up to Jack with a woman in a lab coat she had short blonde hair and wore a skirt and white shirt under the lab coat. She stands next to Jack as The Doctor stood on his other side "Jack this is Doctor Weir she the head of this company, she the reason why I went to find you." The tall man whispered to him.
Jack still hadn't said a word as he watches this Ianto read a book while drinking a cup of tea, he wanted to laugh at the way the younger man's lips curl up as he drunk his tea in a satisfied smile "We used DNA of those who have died in the last 15 years, he was on our system Jack if I had known that his DNA was picked I would have called you sooner." She said, with a worried look on her face
"Jack?" The doctor whispered to him
"He's not the same person is he?" He asked, Doctor Weir looked down at her tablet at Ianto's file and bit her lips, Jack looked over and saw the name 'Ianto 120' he felt a lump in his throat and every time he swallowed it felt like it was growing as if it was ready to suffocate him
"No, we can't clone this is not the man you knew well teen." She said, Jack looked at her "He is 19 years old, the DNA we spliced with his had an un for seen side effect he cannot age pass 19 we are unsure how it happen as the other with the same DNA are aging normally." She told him
"I want to speak to him." He said, as he walked passed her and the Doctor.
Jack walked up to the young man as he rubbed his hands on his trousers "Ianto?" He called out, the young man turned to look at him with bright eyes brighter than Jack as ever seen
"Hello." Ianto said, as he stood up a bit too fast. Jack reached out and grabbed his hips to steady him and then looked into the younger face of a man he once loved. "T…Thank you." He smiled as he kept the man's hand on his hips "Have we met before?" He asked
"Not in this life." Jack smiled softly
"But before?" He asked, as he tilted is head with soft look on his face, Jack felt something bubble up inside of him
"Yes before." Jack swallowed that painful lump and then kissed Ianto on the lips.
The young man froze as he felt the older man's lips the hands tighten around his hips and pulled him closer. Ianto gasped as his hands gripped Jack's coat and something clicked in the back of his mind and he kissed him back. He found himself unable to stop kissing the man back as the large strong hand warped around his waist and held him. "For god sakes Jack let him breath!" The Doctor yelled as he pinched the bridge his nose.
The dark haired man pulled back and looked down at the younger man and held a sad smile as he moved his hand to cup his face and kissed his forehead head. "Ianto." He whispered, he knew this wasn't the Ianto Jones he use to kiss against the wall this was not the man he would lay out on the bed and take him through the night. This wasn't the same man he loved who died in his arms this was a second chances. "Run away with me."
