Series 9 Episode 8 discussion

[Byatil]

Well, if we accept the theory that Lucas is suffering from split-personality disorder, then the plot somewhat makes sense.

Lucas was the dominant persona, whilst the traumatised John was buried deep within L/J's psych. Whilst Lucas was the dominant persona, he had no recollection of ever encountering any other version of himself. I'm not quite sure how multiple/split-personality disorders work, but someone once told me "it's like a revolver", with each different personality surfacing just as a revolver shoots out different bullets. If we accept this theory to be correct, then it is possible that the dominant Lucas persona simply had no idea of the John persona (as it was so deeply buried within him), that the Lucas persona constructed an entire recollection of a past life (the brain can apparently do tremendous things under trauma), and that all it took for the John persona to resurface and become dominant was the right trigger (...Maya? Or Vaughn. The triggers were poor ones, but if we accept them as triggers it makes a bit more sense).

We then see John in 9.8 constantly struggling with Lucas, as Lucas obviously wants to help Harry understand, whereas John is intent on destruction (of himself and others). If we view 9.8 as L/J's internal battle of different persona's, then I think it almost makes sense?

Either that or there really is no plausible explanation whatsoever for this storyline. You be the judge

On a different note, I would love to ask RA what his interpretation of this storyline is, and how he went about portraying Lucas' downfall. Because I think he may be the only man on the planet who will ever understand why Lucas acted the way he did in this series!
