My mind's a blank - what's the big plot hole in Living Witness, is it that there's an EMH copy?
They can't copy him before that episode. But they manage to make a backup module, promptly lose it, then can't copy him again later.
Back on topic... this is hard. They're both great episodes, but in the end a great doctor episode vs a great Kim episode... Doc wins. Timeless.
