I'm currently catching up on the final season of Doctor Who on Netflix Belgium, Season 8, before the BBC takes it down at the end of the month. I'm currently partway through Episode 7, Kill The Moon, and from what little I noticed so far, combined with the blurb, it contains an alien spider.
Now, I'm arachnophobic, and while I might be able to watch it, I'm not sure I might be able to sleep afterwards. The episode with the Donna Noble introduction already was a bit creepy, and the teaser at the end of S8E06 showed a quick image of the alien. I'm still not convinced that the nightmare about a giant spider crawling out of my ceiling later that night was because of my sleeping conditions and not because of that teaser.
I'm seriously considering skipping this episode and going to episode 8, but the season arc about people ending up in heaven when they die has piqued my curiosity and I don't really want to miss some vital clue about this, especially since it's the main meat of the season finale.
What parts related to Heaven are shown in the Kill the Moon episode of Doctor Who? Obviously spoilers are fine.
