The Doctor knocked on the Maitland's door and waited for somebody to answer. In the end, Angie answered and she said, in an almost robotic tone,
"Clara's upstairs. Come in and wait." He let Angie lead him into the living room and fidgeted while he waited.
As the Doctor waited for Clara he though to himself
"how am I going to tell her? How will she react? What if she doesn't love me back?"
All these thoughts went through his brain, causing worry and fear to come crashing into the Doctors mind. He started to feel his hearts beating faster out of fear and excitement. Which emotion was stronger he didn't know, but what he did know was that he needed to tell Clara his true feelings towards her.
Footsteps coming down the stairs interrupted the Doctor's thoughts. He straightened his bow tie and prepared to tell Clara the truth about what he felt towards her. When she came into the Doctor's view though, everything suddenly vanished from his mind except for the thought "she…she's beautiful."
Clara was dressed in a bright red dress that went down to her knees. She asked "why so quiet, chin boy?" The Doctors face went almost as red as Clara's dress and he said quickly, trying and failing to mask his blushing, "I've got something to tell you Clara." Claras heart missed a beat as she heard this.
Clara said "yes Doctor, what is it?" The Doctor walked closer to her as he said "Clara…ever since I first miss you I've been hiding something from you. I came here to tell you that I…that I love you and never ever want to leave you. I want to stay with you forever."
Clara replied "why would I ever want to leave you, my Doctor? I love you. I want to be with you." Both the Doctor and Clara leant in towards each other, not being able to resist kissing the other. They shared a long and passionate kiss and the Doctor's brain stopped thinking and started enjoying the moment for once. Clara noticed this and said smirking, when they broke apart, "Do I make your brain turn into jelly Doctor?" The Doctor answered, still dazed, "yes…I mean no of course not!"
She smiled, knowingly, and pulled him back towards her and started kissing him again, this time taking the lead. He tried to stop her, but Clara wouldn't let him go and soon the Doctor stopped trying and just let Clara take the lead. She knew more than him, anyway,
When they broke apart for the second time, the Doctors eyes were glazed over and for once they looked happy. Clara shouted down the maitland kids and said "go out and see your friends for a few hours." The kids did as they were told and went off to their friends houses, Clara turned back to the Doctor and said, cheekily, "let's go and make use of the snogbox, eh?" He just nodded eyes still glazed as he followed Clara into the TARDIS.
Within the year the Doctor and Clara were married. A year after they were married, Clara discovered she was pregnant with the Doctor's child, news which he was overjoyed with. They lived long and happy lives, the Doctor finding a way to let Clara live by his side forever.
