The Doctor frantically shoved open the TARDIS's door with his shoulder. Clara struggled rather ineffectually in his arms. "I'm fine! Will you just put me down!"
He gently laid Clara down on the floor of the control room, and shrugged out of his jacket. Raising her up carefully, he slid it beneath her head.
"Doctor!"
"Good, you know who I am," he muttered, carefully prodding the nasty lump on her temple.
"Of course, I do! It's just a bump on the head." Clara's expression softened as she read the raw fear in the Doctor's eyes. "It's fine, really. Now stop fussing, and go save the universe!"
"If you're sure…"
"I am. Now run!"
"Right then." The Doctor grinned down at her, then dropped a tender kiss on her forehead. "Don't go anywhere, all right?"
The Doctor gently stroked Clara's hair back from her face and carefully laid a cool compress on the rather spectacular lump on her head. She was cuddled against his side, wrapped in her favorite red shawl, and she seemed so fragile and vulnerable. He recalled the absolute terror he'd felt when he saw that rock contact with her skull. Unconsciously, he tightened his embrace.
"You're fussing again," she complained drowsily.
"Sorry, love," he murmured, dropping a light kiss on the top of her head.
Clara opened her large brown eyes and looked up at him. "You haven't cleaned up that scrape on your chin," she scolded.
"It'll keep," the Doctor said indifferently. "It was more important to look after you."
"What, Time Lords don't get infections?" She struggled to sit up, reaching one hand towards his face.
The Doctor caught her hand and gently kissed it. "Shh…just rest, now. It's not important. I'll be fine."
"So will I. It's just a bump on the head. I don't know why you're carrying on so."
"Clara, when I saw you fall, I thought I was going to lose you again. I don't think I could bear that. I lost you twice…"
"And you found me again," Clara reminded him gently. "And I'm here, now, with you."
"I'm so very afraid of losing you, of being alone again," the Doctor said slowly. "I don't do well alone. I tend to…get muddled…lose focus. You are the light in my hearts, Clara Oswin Oswald. I'd be lost without you."
"You could turn a girl's head, talking like that." Clara's words were light, but her smile was very tender, and her fingers were interlaced tightly with the Doctor's. And that was all the answer he needed just then.
