Series 9 Episode 8 discussion

[HellsBells]

I think it shows just how 'awkward' the writing of series 9 appears to be, because I personally still can't decide whether Lucas was purposefully deceitful and Lucas was merely a legend created by John Bateman. Or as has been said that it was some sort of split-personality issue and Lucas could not remember John Bateman. I think the writing wavered between the two possibilities leaving a lot of ambiguity.
And lets face it, they didn't 100% kill off Lucas, we were left to assume he jumped.
