Disclaimer: Not mine. This is the scene where V kills Lewis Prothero.
"Don't worry, I've made sure our reunion won't be disturbed, Commander Prothero."
"Stop that! Why do you keep calling me that?"
"That was your title when we first met, all those years ago."
"You. It is you!"
"No, not U, it's V! Honestly, you'd think it'd be obvious by now. The roman numeral 'V' on my door at the detention centre, my entire speech on the TV that everybody and his brother saw with my blazing V symbol in the background, the explosion of the Old Bailey where the fireworks pattern created a V – it's not that hard to deduce, is it? It's really too bad, you missed my fantastic monologue where I used no less than 50 words that started with V - that really gives me away. I guess I'll have to repeat it for you, to get the point across: Voilà! In view, a humble vaudevillian veteran, cast vicariously as both victim and villain by the vicissitudes of fate. This visage, no mere veneer of vanity, is a vestige of the vox populi, now vacant, vanished - "
"God, listening to this is worse than any poison - just put me out of my misery already."
