I just finished rewatching Kingdom Hospital as the first time I watched it was before I'd read the Dark Tower. I know that SK added a lot of DT referrences into this series so I was watching for these links.
All the way through the series they show a drinks machine with Nozz-a-la all over it but at the very end of the last episode, the drinks machine has changed to Pepsi. Can anyone explain to me why/how, in the context of the Dark Tower series? Have they actually returned to a different version of their world? I'm slightly confused! Thanks
