It had been a while since Clara went to her room. She's usually back in the console room right now, thought the Doctor while fidgeting with the TARDIS controls. After another 5 minutes he couldn't stand the silence any longer and decided to go check up on her. The Doctor weaved his way through the halls until he arrived at Clara's bedroom. He knocked twice before letting himself in. Clara was sitting on her bed, staring blankly into space. She probably didn't even notice him enter. "Clara?" said the Doctor, snapping her out of her daze. "Are you alright?" he asked. Clara looked startled for a moment.
"Hm? Yeah, yeah I was just thinking" she answered. The Doctor sat down beside her on her bed.
"What were you thinking about?" he asked. Clara's expression was unreadable, though he could tell that something was troubling her.
"About what you asked me earlier in the console room, whether or not I felt safe." Clara said with the same worried look on her face.
"Well…do you feel safe…?" the Doctor asked. He couldn't help but fear that she would say no.
"You see that's what's bothering me." Clara started "Every day we go on these insane adventures, facing death each time. I've come across monsters, aliens, and the most dangerous of situations. I've nearly died numerous occasions and yet I still feel so…" but Clara couldn't finish. It was as if she was afraid to. The Doctor was staring at her now, puzzled. He wasn't sure what to tell her. He had already seen Clara die two times and it scared him that he might just witness it a third time.
"Safe" Clara said. "I still feel so…safe. I don't know what it is. Part of me thinks that I shouldn't feel safe at all considering the position I'm it but I still can't help feeling-" the Doctor pulled her into a tight embrace before she could finish her sentence.
"You should feel safe, Clara. There's nothing wrong with feeling safe because I'm going to make sure that I never lose you." Not again he thought to himself. Clara gripped him tightly as he stroked her hair. The Doctor placed a kiss on her forehead before standing up. "Come on then" he said with a smile and took Clara's hand. "Places to be, worlds to save". Clara was smiling now as well.
"That's what we do"
