10 Doctor Who Scenes More Terrifying When You Know The Truth

10. The Tragedy Of Sky Silvestry

As the host of the mysterious Midnight entity, Sky Silvestry is utterly terrifying. But in the moments before she gets possessed, she’s pretty terrified herself.

It’s hard not to feel sorry for her as she retreats into the corner of the Crusader 50, knowing the creature has picked her as its first victim. And given that she’s just been dumped by her partner, she’s not exactly in the best mental state to begin with – and that’s putting it mildly.

Even if the Midnight entity hadn’t struck, her trip would've still been tinged with tragedy, because upon reaching her destination (the Sapphire Waterfall), Sky was planning to kill herself.

This extra bit of backstory isn’t explicit in the script, but as Russell T Davies revealed on the episode’s DVD commentary, there’s one crucial line that gives the game away:

“She’s on her way to a waterfall palace, but she says ‘I’m on a schedule’, which is like, what for, what on earth are you going to a waterfall on a schedule for?”

Midnight is a scary episode as it is. But knowing that this was going on in the background (and is potentially why the entity picked Sky in the first place) makes it a whole lot darker.
