(Spoilers for The Climb below!)
This whole scene is pretty brilliant (oh, that speech/reveal, how wonderful/horrific!), but hot damn, Conleth Hill. I can't get over the way he says 'But what do we have when we abandon the lie? Chaos.' It's like every word that perfectly tumbles from his lips is liquid gold.
I could very happily listen to him read the phonebook. Or have a conversation with Tom Baker. The aural brilliance would astound me!
