Doctor Who: Eve of the Daleks’ time loops explained

We break down every loop in the new festive special, and puzzle out some of the confusing “rules” of the episode.

New Doctor Who New Year’s special Eve of the Daleks traps the Doctor (Jodie Whittaker) and four others in a deadly time loop, with our heroes forced to run from and outwit a squad of Daleks, only for everything to reset and force them to try again a moment later.

It’s like Groundhog Day, basically, as Dan (John Bishop) notes at one point – though there is a twist. Unlike other eternal time loops, this one’s getting shorter by a minute each time. And also unlike other time loops, there are loads of Daleks trying to kill you within it (which would be a great deleted scene with Bill Murray, admittedly).

It’s all a rollicking good time and by the end you’ll be left with a big smile on your face – but you’d be forgiven for being a bit confused by the time the credits roll as well. Wait, why did the loop lose a minute every time? Who made the loop? Were the Daleks trapped in it too? And why was it so important they got out at midnight – couldn’t they just hide until the loop finished, then exit the building?

We’ve spent a while puzzling it out, and we think we’ve just about got it nailed – so here’s our answers to any lingering time loop questions, plus a full breakdown of every loop in the episode.

Who made the time loop?

As it turns out, it wasn’t the Daleks trying to trap the Doctor – they did that with a simple forcefield over the door. No, the time loop was seemingly created by the TARDIS itself to try and protect the Doctor, Dan and Yaz (Mandip Gill) from their certain death.

It may also have been a side effect of the special "reset" the TARDIS was going through, which also attracted the Daleks’ attention in the first place. In other words, the loop was a good thing – helping the Doctor, not the Daleks.

The Daleks plan was just to seal the building and do some shootin’, and they got more than they bargained for.

Why did the time loop get shorter?

As noted, the main twist on time loops in this episode is that the loop got shorter each time, giving the Doctor and co less time to escape the Daleks with every go-around.

The Doctor explains this is because "whatever’s made the time loop can’t sustain it", noting it might be "under some sort of pressure." In other words, the damaged TARDIS is losing its grip on the loop gradually, making it a limited-time protection for the Doctor and her friends.

What made the loop reset?

This might be the crucial point in understanding this episode – unlike Groundhog Day, it seems like the loops don’t reset at a particular time. Rather, the loop resets when characters die – exactly the same as hit Netflix series Russian Doll.

In other words, the loop was protecting the Doctor from death by giving her another go. And that’s also why it was important for the gang to get out of the building before the final loop closed – once that was gone, assuming they were still trapped in the building, it was only a matter of time before the Daleks finished them off for good.

Note that you never see a reset when any of the characters are left alive – it’s death, not a deadline, that marks the change. All the Daleks have to do is kill everyone enough times, and the loop will stop.

Were the Daleks trapped in the time loop?

No – the Daleks were teleporting in from an outside location, and the loop only existed within the self storage building itself. This is why the Daleks were able to appear in different locations during the loops – though what this means for the two that Nick (Adjani Salmon) killed is anyone’s guess.

It’s also why the resets only happened when the human (or Time Lord) characters died, rather than any Daleks. Presumably, there were only five Daleks assigned to this mission in total, which is why there weren’t any more teleporting in after the loop closed.

Why did they have to get out at midnight?

Here’s how the Doctor explained her end goal during the episode:

"If we can stay alive and be outside the building when midnight hits, we might stand a chance of getting clear of this."

Frankly, this point is a little confusing. How did the Doctor know that the Time Loop couldn’t just continue on, even if the beginning was getting shorter? If they survived long enough past midnight and kept going, presumably the loop would just tick a minute forward and reset them from that point?

Well, possibly not. Though it’s not made entirely clear in the episode, it seems likely that just before midnight was when the time loop was first activated – the first death of the Doctor, Yaz and Dan, in other words. The loop was a reaction to this first death, so it stands to reason that this is when it naturally ends – otherwise it’s not a loop, it’s just an infinite respawn.

Yes, the Doctor and co. could evade the Daleks past this point – but with the building still sealed and the Daleks after them, it’d only be a matter of time before they were killed again, this time without the protection of the loop. So the Doctor’s plan makes sense – use the last couple of loops to draw in the Daleks and destroy them (so they can’t just keep going after them, this time without protection) and escape the building, which they’re trapped in by a Dalek forcefield (The loop itself didn't trap them inside).

That make sense? No? Well maybe we can work it out further.

How many loops were there in Eve of the Daleks?

We counted nine loops – Sarah was right with her estimate that she’d been killed eight times over the course of the night – and they were as follows:

And then it’s midnight. Happy New Year!

It just about all holds together, we think, though the rules are a little confusing. For example, Sarah’s mother calls at four minutes to midnight initially, but calls later once the loop progresses beyond that point. Was this a second call, or the original delayed?

Does this mean they’re being put back at different points in the timeline, or just being given less time from the same points? And are characters only 'reset' from their position at whatever time it is from the first loop, or the loops that came after? Surely the latter has to be true, or some of them would be dead when there's only a minute to go?

In the end we’ll probably have to wave our hands about a bit and say wibbly-wobbly timey-wimey – but in an episode this fun, it probably doesn’t matter that the whole thing isn’t completely airtight. And we're sure that in the months between this and the next episodes, fans will have managed to work out how it does make sense after all...
