He hugged Pete and Jackie Tyler goodbye and walked with Clara back to the TARDIS, while explaining who Rose's Doctor was finally. Clara was absolutely shocked by the whole story, and he had to admit it was one of his stranger ones. Once back into the blue box he fidgeted with controls again and started the journey of Clara's brilliant plan. He started to think of truly how his friends were the best of him, how each one of his friends surprised him by their intelligence and integrity. Sometimes he felt like the dumbest person in the whole universe, and he probably was. The more you know the less you know someone once said.
They went back a week ago before Rose's Doctor died, when he and Rose were asleep. He didn't look the same as he remembered, he was so much skinnier and paler than usual.
They woke him with a shock, careful not to wake Rose, they led him into the TARDIS, where they could reveal the plan ahead of them. There were only a 12 hours before he died and they needed to move fast.
Clara and the Doctor took him forward in time for the birth of his and Rose's son, Jack. An hour before his birth they arrived to the eager Rose Tyler. The Doctor and Clara let them have their privacy by wandering the hospital halls.
"What do you think it's like for her? Do you think she waits around for him? I think it'd drive me crazy having to wait and not really knowing when I'd see someone I loved." Clara casually asked.
"Naw, Rose was never one to wait around. I think she'd look forward to it, but she will be something great. She always was." If anybody knew Rose, it was him and the last thing she ever did was wait.
After a few hours and only 9 hours left until Rose's Doctor will take his final breath, they had to keep moving. Upon his request, they watched his son grow up. The Doctor, Clara, and the human Doctor were there for baby Jack's first steps, his first day of school, graduation, marriage, all the moments that he wanted to see with the few hours he had left to live.
With only one hour left before they needed to get him back to his death, he had one final request, to be with Rose while she died.
She didn't live as long as the Doctor would have liked, he wanted her to live forever, but humans cannot regenerate no matter how much you want them to. When they took him to see his wife, she was only 63. The timelord hated to see her like this, but they weren't her for him, they were here for her. It's always been for her.
"I knew you'd be here for this," Rose said with a smile when her Doctor existed the TARDIS.
"I've always been here," he climbed into bed with her and held Rose one last time as she slowly drifted off to infinite sleep.
"I'm ready to die now Doctor, I am at peace." he declared. All three of them gathered into the TARDIS with a sad lingering silence.
"Who was she to you, Doctor?" Clara wondered in the TARDIS console room. "Was she a companion like me?" He knew she was asking more than if she just casually travelled with him, he had to tell her the truth. Something he didn't usually do.
"She was, she was ripped away from me. I cared about her a great deal, and she cared about me. That's why I gave her human me." he answered. The Doctor could hear the memory of her voice being sucked into the void before Pete saved her.
"Because you knew she loved you and could take care of you?" she questioned, "the human you?"
"Yes."
"I care about you." she confessed with a look to the floor.
"I know." he walked forward with little space between them.
"I don't know what I'd do if we were ripped apart." Clara stated with more confidence in her voice. She looked up at him, their eyes meeting.
"I'd tear the universe apart to find you." he proclaimed as he sealed it with a kiss.
