Clara’s face grew softer, her expression changing from the sudden anger to a more subtle one with a hint of disappointment. “Nothing happened, but that doesn’t mean you’re invincible.” He of all people should know that, but she acknowledges that it’s just like the Doctor to brush something like that to the side. As if it isn’t necessary to worry about him. “I told you I’d stay, didn’t I? Promised I’d stick around whether you changed back to normal or not.” What appeared to be an entirely plausible chance to him wasn’t even an option for her. No matter how much someone screws up, on purpose or accident, there’s no possible way for Clara to just cut out. Even if she wanted to. “Do you really have that little confidence in me, Doctor?”

"I'm not trying to say I'm invincible," He insisted with a quiet scoff. "I'm just sayin' that you make me out to be far more of a goof than I am." Quickly, he takes his hands to her face, holding onto her cheeks and leaning down, getting at eye level with the girl. "Okay, no, m'still a bit of a fool. But I do know a bit of what'm doin'--I am 1300 years old." Standing up straight again, he looked down at her. The year'd been long; and there were times where he nearly hadn't come back. It became too hard, though, the not knowing. Trenzalore'd taught him that. It was better to know than live in mystery. "No, no," He quickly retorted, bringing a hand to run through his hair. "If there's anyone, Clara, anyone, I've got confidence in...it's you. It's me I haven't got th'confidence in, I s'pose."
