For the Doctor, his devotion to her at this profound level is something new and he doesn't entirely understand it, either. While he's charged himself with the care of everyone here (whether they know it or not), there is something wholly different about his commitment and attachment to Vanessa. Truthfully, he wasn't entirely aware until this moment, until speaking the words felt not only necessary, but also like the only truth that's made any sense at all in many long weeks. It means, however, that he's had no time to even think on it, why he felt compelled to say such a thing, and why he would break all of his own rules for her, specifically. Everyone is important, yes, but Vanessa is important to him in a way that he's still trying to sort out.

As often happens for him, though, his own lack of understanding of himself at this moment doesn't preclude him from caring for her in whatever way she'll allow.

"Dangerous is sort of my thing. I know all about danger, I don't hide from it, I run towards it. Well, sometimes, admittedly, it's a bit of a slow jog," he tries for a brief moment of levity, a little softness in his eyes.

"What's dangerous about my sweetness, though?" He asks gently, stroking his thumb across her knuckles. "You're safe with me. Or, I hope you feel that way, in any case. If you asked me to leave, though, I would. If you asked me to stay, I would."

If you asked anything at all of me...

Would he? Anything?

Another question to ruminate over when he's alone. How far would he go for her, truly? And why?
