Saw straight through his 'tears of self' when glorying in his Saviour delusion early doors (in the garden when his 'marriage to the dying girl' was revealed). No idea about the validity of any voice recordings - that's for the courts to decide via voice analysis - but his rage when Marc put him in the shadows confirmed to me that I was watching a narcissist who is very easily offended when upstaged or (more pertinently) is exposed as a fraud.
That was the highlight of the series to me - watching an intelligent wind up merchant destroy him with just a smile.
