She could hear her gentle footsteps make a faint tap on the metallic floor, no matter how softly she walked. She saw the TARDIS react to her being up, it's noise increased, she 'shhh'ed it, fearing it will wake him if he is in fact asleep, she had passed her bathroom, the library and a few other rooms that she'd never even entered. As she neared his room she saw his door was left ajar, but he couldn't have been up or the TARDIS would have reacted, he obviously didn't like to close it when he went to sleep. By now it was 11:48pm, twelve minutes to Christmas, or TARDIS Christmas at least (they had their own time system so they'd know birthdays, annual events, seasons etc.). She knew the Doctor had gotten her a present, she walked in to the library when wrapping paper and selotape surrounded him, he jumped up to cover what he was doing, from what Clara saw, he wasn't a great present wrapper…
They'd each gotten each other a few presents, some were under the tree, and some were hidden away until morning, Clara had bought him a bow tie when they were in New York, 1947, it was forest green with black polka dots, very Doctor-ish along with a new hair comb, since his snapped in his pocket, some new hear gel, since he used all of his up and some woolen socks she'd knitted herself. She was worried she'd gone a bit overboard, but she kept thinking of things that he'd love, and she wanted him to have a happy Christmas, the way he acted about it seemed that past ones hadn't been great. This sometimes bothered Clara, that she knew so little about his past; only recently had she found out he had traveled with numbers of humans, she wasn't even the first. The times that it always bothered her was when he asked for the TARDIS interface, because it always projects a person that the Doctor was close with, cared for, and the TARDIS has a knack of always coming up first with the same woman. The Doctor gets pretty angry when she does, because he always sonics it so it disappears immediately, Clara had never really even seen her properly, all she'd seen is that she has blonde hair, and she's pretty, but she'd never seen enough to know how she really looks.
Just then, Clara remembered that she had to give the Doctor another present, but not from herself. It had been quite strange actually, because when they were in 1947 New York, a woman came up to Clara, more walked past her. She had flaming red hair and legs that went for miles, she just shoved a little wrapped box in Clara's hand and walked off, it simple said "Dear Doctor, Merry Christmas! Love and hugs, the Centurion and the Girl who waited x", Clara didn't have time to think about it, because at that moment, the Doctor whizzed her off and she just shoved the box in her pocket, Clara had to find it for Christmas morning, it must've still been in her pocket. She contemplated going to find it, but she figured she could in the morning.
She arrived at the Doctor's door, she felt nervous, she didn't know what she was planning to say to him, she didn't even know why she was there, she just knew she wanted to see him. She gently pushed the door further open, and slowly poked her head around the frame…
