“ … and do you think I never fear I’ll awaken one day to the smell of engine exhaust, and the sight of the TARDIS dematerializing, with you inside, afraid of yourself, me, us, what we are, were, or never will be,  abandoning me again?  We remain together not because we have no fear of what we could do to destroy each other, but despite that knowledge.  Every day, love is a choice, that’s what you told me.  Because what we are together is more than our fear of being annihilated by the person who knows us best in all the cosmos.  Or am I wrong?”
