The Caretaker (Doctor Who)

"The Caretaker" is the sixth episode of the eighth series of the British science fiction television programme Doctor Who. It was first broadcast on BBC One on 27 September 2014. The episode was written by Gareth Roberts and Steven Moffat, and directed by Paul Murphy.

In the episode, the alien time traveller the Doctor (Peter Capaldi) goes under deep cover as the caretaker of Coal Hill School—the work place of his travelling companion Clara (Jenna Coleman)—to stop a world-threatening robot nearby called the Skovox Blitzer (Jimmy Vee). The Doctor also comes into conflict with Clara's boyfriend, former soldier Danny Pink (Samuel Anderson).

The episode was watched by 6.82 million viewers in the UK, and received positive reviews from television critics.

Plot
Clara struggles to balance between the excitement of being the Twelfth Doctor's companion, the normality of teaching at Coal Hill School and keeping her relationship with Danny, a former soldier.

The Doctor alerts Clara he will need to go alone on his next outing under "deep cover", but Clara is surprised the next day that he has been hired as a temporary caretaker. Privately, the Doctor explains that a murderous robot, the Skovox Blitzer, is near the school, and has already killed a community support officer. If he does not intervene, it could destroy the Earth. He has been planting devices around the school to create a time displacement vortex in order to send the robot far into the future where it cannot harm anyone, and has an invisibility watch to help approach it.

Danny observes the Doctor's interactions with Clara and becomes suspicious of him. He inadvertently finds one of the devices the Doctor has planted and interferes with its settings. When the Doctor attempts to carry out his plan, Danny's change causes the Blitzer to only be displaced forward by 74 hours. After seeing the Doctor again approach Clara discussing this change in plan, Danny accosts Clara, believing she is an alien, during which Clara admits her love for Danny. The Doctor argues Clara has made a "boyfriend error" for dating Danny. Clara lets Danny use the invisibility watch to see how she interacts with the Doctor. However, the Doctor is aware of Danny's presence, and Danny compares the Doctor to an officer before leaving. Meanwhile, student Courtney Woods has come across the Doctor's TARDIS and starts following him around.

At Parents' Evening, the Blitzer rematerialises earlier than expected. The Doctor and Clara inadvertently trigger the Blitzer's self-destruct mechanism, but Danny's timely intervention allows them to force it to stand down. The Doctor offers Courtney a trip in the TARDIS as he leaves the inactive Blitzer in deep space, but Courtney ends up getting sick and throwing up within the TARDIS. On Earth, Danny tells Clara he is impressed with her resolve under the Doctor but not to let him push her too far, or otherwise their relationship will be over.

Meanwhile, the community support officer awakens in the Promised Land, also known as the Nethersphere. The interviewer, Seb, informs him of his death and their whereabouts, and states that Missy is too busy to deal with him.

He called The Caretaker "satisfying despite the occasional slip into soap opera silliness."

Neela Debnath of The Independent gave the episode a negative review, calling it "A bland Earth-based adventure that failed to excite."
