It's fair to say that Westworld has been exactly the success HBO was expecting (and needing).

Having racked up impressive viewing ratings with every new episode and just this week been officially handed a second season, the sci-fi western series has become the source of debate leading to intense fan theories not dissimilar to the furore whipped up by Lost a decade ago.

Impressively, after just seven episodes, the series' subreddit page has over 100,000 subscribers. It turns out one such user is co-creator Jonathan Nolan who has fuelled excitement by nonchalantly posting an unseen clip in reply to a fan question.

User mattdezine was wondering what happens to all of the paintings drawn by Dolores (Evan Rachel Wood), one of the theme park's 'hosts' who's narratively programmed to paint by the river.

This was where Nolan stepped in, posting: "This doesn't like anything to me" (the line commonly spoken by hosts when presented with something that causes them to question their existence) alongside a gif showing exactly what happens with those paintings.

The most exciting thing about Westworld is how Nolan and fellow creator (and wife) Lisa Joy are reported to have an entire five seasons mapped out.

A trailer for episode eight was unveiled earlier this week teasing the aftermath of that huge cliffhanger dropped at the climax of the series' previous episode.
