The Doctor woke up to the sound of a piercing shriek (it nearly broke his sensitive eardrums), and then a rough shove that had enough strength to push him off the bed and onto the floor, tangled up in the sheets and part of the duvet.
Struggling to get untangled, he felt the duvet being pulled the opposite direction from his position. He looked up to see Clara, hair tousled and eyes wild, staring at him in shock, while she clutched the rest of the duvet, frantically trying to cover herself.
"Clara?" he cautiously asked. He managed to get the duvet untangled from himself so she could pull it back onto the bed. In the process he also got the sheet off, uncovering himself. Clara yelped.
"What're you doing in here in your underpants?" she yelled, with her expression going from horror to anger. "Why're you in my room, in my bed?"
The Doctor blinked. "It's our bed, love. Yours and mine. I put you in it several hours ago, and about an hour ago I thought I'd join you so I could be there when you woke up. How are you feeling?" He cocked his head to the side, giving her a look of concern.
"Our…" Clara trailed off at the implication. "You mean…you and I…we…we…." Her brown eyes got wider and her pupils characteristically dilated with extreme emotion. From Clara's befuddled perspective, she knew the Doctor most likely fancied her, but this was a little too forward. She had no memory of willingly climbing in bed with him, so somehow, he must've been responsible for inviting himself under the covers with her. That was more than a little alarming and a bit creepy, to be honest.
However, the look on the Doctor's face was taking her by surprise. He had an expression of honest confusion, as if she'd said something bizarre. He blinked a couple more times at her, then scratched his head (which had the most impressive bed hair Clara had ever seen. For a moment she wanted nothing more than to reach over, run her fingers through it and straighten it).
"Clara," the Doctor said slowly, "you do remember that we're married…don't you?"
"Married? When—how—where—did we get married?" she stuttered, getting more confused and alarmed by the minute. "I don't remember getting married-!"
He gave her a look as if he was considering something unpleasant. "What's the last thing you do remember?" he asked.
"We…were…on Trenzalore…I…jumped into your time stream…" Clara's hand went to her head, and with trembling fingers she touched the side of it. "I saw a strange man you said was one of your faces, and then…I don't remember anything else."
The Doctor sighed. Obviously, that was a long time ago, which meant Clara was experiencing something else that often happened to him after regeneration—amnesia.
He stood up, holding the sheet and then wrapping it around himself for the sake of Clara's modesty caused by her confusion over their relationship. Tilting his head to the side, he smiled gently at her. "A lot has happened since then, love. Not too long ago, though, we did get married. You're just experiencing some regeneration amnesia. It'll pass in time, and you'll remember everything."
"Regeneration-? Did—did you regenerate or something?" She appeared to be getting more baffled by the minute. "Was it when you rescued me from your timeline? And if you regenerated, why am I having amnesia? Did I black out?"
Rolling his eyes with a do-we-have-to-go-through-this-again expression, the Doctor plopped down on the end of the bed, careful to make sure he was a proper distance away from Clara, who quickly moved as far as she could from him anyway.
Groaning in irritation, the Doctor decided to fill Clara in on the blanks in her memory. "You did black out back then, but we got out of my timeline okay. I had to help you mentally adjust to your new multiple memories before you went back to the Maitland's. They got a new nanny, you got a job as a teacher, then we went on a big adventure where you helped me rescue Gallifrey. Then Christmas came. We got separated by time and space because I was an idiot as usual. I became a very old man and died, only to regenerate into a cranky Scot. You and I were reunited, had some adventures, and then you almost married some other bloke. I ran into River Song, she accidentally poisoned me then dumped me, and I landed on your rooftop after I regenerated again into this form. We made up and got married. Then we went to a dinosaur planet with Vastra where you got bit by a poisonous lizard, and died. Then you regenerated. And now here we are."
Clara stared blankly at him. "I don't remember any of that," she stated.
"It'll come back to you," he assured her. He stood up, clutching the sheet to keep it from falling. Swaddled by the fabric, he hobbled to the door. "I'll go off to the wardrobe to get dressed, and leave you to rest."
Watching him leave, Clara began to relax. She lifted a hand to her head to comb her fingers through her tangled hair. Releasing her death grip on the duvet, she glanced down at her left hand, where a beautiful ring sparkled on the third finger. Bringing it level to her eyes, she gazed at it in wonder. He'd said they were married, and here was some proof. So why didn't she recall any of it?
She dropped her hand to her lap and clutched at it with her other one. If only she could think straight! Her mind felt muddled, confused. All she remembered was Trenzalore, and being split into a million different Claras, all desperately trying to save the Doctor.
There was something else that distracted her from concentrating. The loud growling coming from her stomach, and the driving hunger it was signaling. Food. She had to have some food, and she had to have it now. Clara had never felt so starved for sustenance as she felt at that moment. Throwing back the duvet, she stood up quickly, and then ran to the bedroom door. Once in the hallway, she paused. Which way to one of the Tardis' many kitchens?
Lifting her chin, she addressed the ceiling. "I know we've had our differences," she stated, directing her remarks to the Tardis itself. "But I could really use a fully stocked pantry or kitchen right now."
To her left, a corridor suddenly lit up with a red glow. Clara took it as a sign that the Tardis heard her, and she bolted in that direction.
