Doctor Who Theories – Oxygen – Week 5

Doctor Who Theories

Hello everyone. This weeks Doctor who was very difficult for me to watch. Zombies im space!! Seriously, I really don’t like zombies but for the sake of the Doctor and you dear readers I persevered in order to deliver this weeks theories roundup. To see how the theories have developed up to now you can read last weeks post here.

‘Oxygen’ Overview

Last week we saw a nod to horror films in the episode ‘Knock Knock’ and this weeks episode ‘Oxygen’  tipped its hat towards the space travel sci-fi genre.

The Doctor  clearly missed travelling in space. So much so  that during a  crop rotation  lecture he ended up talking about the dangers of space, including a  take on an iconic Star Trek line. “Space, the final frontier.  Final because it wants to kill us”.

To satisfy his longing to travel and despite the disapproval of Nardole whose job it is to keep him earthbound the Doctor decided to take Bill on another adventure, this time into space.

Their destination was a  mining space station, chosen by the Doctor after he received a distress signal from it.

unbeknown to the Doctor, Bill and Narodole when they first land on the station,  most of the crew had been turned into space zombies. Only 4 out of the 40 crew members were still alive and the Doctor assigned himself the task of finding and  rescuing them.

The space zombies were not traditional dead come back to life type zombies. In the futuristic station the crew used space suits which possessed artificial intelligence which enabled them to walk, speak, and carry out simple tasks independently. After the suits apparently malfunction and killed the crew members, they continued to function with the corpses still inside.

When the Doctor and Co found out oxygen on the space station had been restricted and was  only supplied via the space suits to those who have paid for it, they were faced with a stark choice. Put on the potentially killer suits or suffocate.

Even with the suits they had limited time to find out how to stop the space zombies and rescue the survivors before the oxygen in their own suits ran out.

This episode didn’t quite reach the same standard as other episodes in the series, although it appeared to be a necessary tool in the overall series storyline. The Doctor compromised his own safety to protect Bill and by doing so damaged his own sight.

The Doctor is blind

Throughout the past few weeks Nardole has warned the Doctor again and again of the dangers of leaving earth. He is obviously scared of whatever is in the vault and believes it is capable of detecting and using any weakness in the Doctor to aid its escape.

Being blind is a massive weakness and is a strong indication that we will see both the resident of the vault escape next week and also that we may see a mid-season regeneration of the Doctor as has been hinted at in various trailers and by Steven Moffat himself.

Humans as the enemy

As mentioned in last weeks post humans are not showing the better side of themselves in this series,  and that is seen again this week.

There is a very  clever use of the term killer suits this week, referring not only to the space suits but also the corporation bosses.

The corporation suits not only decided to make oxygen a saleable commodity in space, but also put a value on the lives of the crew. When they became unprofitable the corporation used the space suits to terminated them.

The Doctor only saved himself and the others   by making their potential death too expensive for the corporation.

The Vault

Obviously  the big theme, the thing that all whovians are talking about at the moment is who is in the vault.

There have been plenty of clues about the vaults occupant on Dr Who websites and in interviews with Steven Moffat and the cast that add to what we have learnt so far in  the programs, so if you don’t want to find out any more than has been shown in the episodes STOP READING NOW.

Are you still here?

Okay, well the first thing those sites tell us is we will find out who is in the vault next week.

So we know when we will find out, the remaining question is who. This can be guessed at from the trailers.  In one trailer at the end of  a previous episode there is a brief clip of Missy lying on something. Her pose reminds me of seeing famous female singers drap themselves over pianos and as we know the Doctor put a piano in the vault I am certain this is how we will first see Missy, the occupant of the vault.

This is backed up by the fact that Michelle Gomez has been credited as being in episode 5 and also the 2 part season finale but John Simms is (reportedly) only in the last 2 episodes.


There was a little nod towards the family theme once again this week. When Bill believed her life was going to end she asked for her mum and we saw a flashback to the picture the Doctor had taken of her mum.

This picture is becoming a regular thing in past weeks and it makes me wonder whether there is more to Bills back story than we have been told or she currently knows.

Bills true identity  is something that is being discussed a lot online. It is something the series still hasn’t addressed to many whovians satisfaction.

I have seen some brilliant theories online but my favourite to date and one which fits in with the family theme is that she is a regeneration of his granddaughter Susan and has had her mind wiped to protect her from some danger.

We have assumed up till now that the Doctors promise and view to stay earth-bound is only to guard the vault, but maybe that’s not the only thing he is protecting?

There have been a lot of possibilities thrown up by this weeks episode but not as many answers yet.  Are you looking forward to the big vault reveal  next week? Do you think there will be a big twist in the story?

    I’m still not convinced it’s Missy in the Vault. It seems too obvious. I am, however, very excited for this week’s episode. Taking the Doctor’s sight away was such a brave move. And now Missy is on the scene… A recipe for disaster?

      Well you’re right there is still the possibility they will play a huge curve ball, they do seem to have been dropping a lot of clues xx

    This episode reminded me of the David Tennant episode in the library. I am enjoying this series much more than the last (I had considered giving up, shock horror!) but still have unanswered questions about the Clara stories that I keep hoping they will come back to. #coolmumclub

      I really didnt like Clara that much so found the last few series a bit dragging because of that. Bill is an excellent companion x

    This series of Doctor Who has been so much better – even last weeks episode, which was the lesser so far, was fab compared to previous! I am looking forward to finding out the twist because, knowing Doctor Who, there will be! #ablogginggoodtime

      I agree with you. I think they have let so much slip out, there must be something they have kept back to surprise us with

    I have to admit,…I don’t watch Dr Who any more but loving the fact that you have gone into such depth theorizing about this! Thanks for linking up to #coolmumclub with this x
