When the Doctor sticks his finger in the jam jar, he only uses one finger and puts it in his mouth. After Rose clears her throat, the next shot of the Doctor shows him with two fingers in his mouth.
Near the end of the episode, when the people Chloe drew are coming back, Rose is disappointed that the Doctor doesn't appear. There is no reason why he should appear there, as he disappeared elsewhere, and she seems to assume, for no apparent reason, that he is not going to come back. She doesn't even check the drawing to see if he is still there. Neither does she think to check the TARDIS.
Events in this episode take place in the same year as the events in Dalek. It isn't clear if the events in each episode are occurring simultaneously.
The poster of Shayne Ward's Greatest Hits show the same picture as his 2006 album Shayne Ward. Surely he would use a different picture.
Huw Edwards, the news presenter, mentions Torchwood though it is not as clear as some of the other references made this series.
Attention to detail - The red Mini that Rose helps to push has a '09' number plate, meaning it was registered in 2009, three years prior to this episode and three years in the future for us in 2006.
The Tarmac Workers are from the East London Council, as printed on their hazard vests.
Rose: So, near future, yeah?
The Doctor: I had a passing fancy. Only it didn't pass, it stopped.
The Doctor: Get out of here!
Rose: What's it say?
The Doctor: It is. It's graphite. Basically the same material as an HB pencil.
Rose: I was attacked by a... pencil scribble?
The Doctor: Hello! I'm the Doctor and this is Rose. Can we see your daughter?
Trish: No, you can't.
The Doctor: Okay, bye.
The Doctor: In those days, everyone had a Tea Party to go to! They had those little cakes, with the crunchy ball bearings on top. You know those, those things? Nobody else in the galaxy has ever bothered to make edible ball bearings! Genius!
Rose: (spots a cat) Aren't you a beautiful boy!
The Doctor: (thinking Rose is talking to him) Thanks! I'm experimenting with back combing.
The Doctor: Fear, loneliness. They're the big ones, Rose. Some of the most terrible acts ever committed have been inspired by them. We're not dealing with something that wants to conquer or destroy. There's a lot of things you need to get across this universe. Warp drive, wormhole refractors. You know the thing you need most of all? You need a hand to hold.
(Rose is digging up the street looking for the Isolas pod, much to the annoyance of council worker Kel)
Kel: You just took a council axe from a council van and now you're digging up a council road! I'm reporting you to the council!
(Rose sifts through the tarmac and finds the pod)
Rose: It went for the hottest thing in the street. Your tar! (laughs)
Kel: What is it?
Rose: It's a spaceship. Not a council spaceship, I'm afraid.
(The Doctor has put Chloe in a trance and speaks to the Isolas, the entity within her)
Isolas: Our journey began in the deep realms. When we were a family. (Chloe begins to draw)
Trish: What's that?
The Doctor: The Isolas mother, drifting in deep space. See, she jettisons millions of fledgling spores. Her children. The Isolas are empathic beings of intense emotion. When they're cast off from their mother, their empathic link - their need for each another - is what sustains them. They need to be together. They cannot be alone.
Rose: Chloe has a power and, I don't know how, but she used it to take Danny Edwards. Dale Hicks. She's using it to snatch the kids.
Trish: Get out.
Rose: Have you seen those drawings move?
Trish: I haven't seen anything!
The Doctor: Yes, you have. Out the corner of your eye.
The Doctor: And you dismissed it. Because what choice do you have, when you see something you can't possibly explain? You dismiss it, right? And if anyone mentions it, you get angry. So it's never spoken of ever again.
Trish: She's a child.
The Doctor: And you're terrified of her. And there's no one to turn to. Cos who's going to believe what you see out of the corner of your eye? No one. Except me.
Chloe: (To the drawings) I've given you friends and you still moan. Moan, moan, moan. You're lucky. You're all together. You don't know what it is to be alone. If you did, you'd be thanking me.
(An old woman, Maeve, walks down Dame Kelly Holmes Close and stops, as if sensing an evil presence. A young woman, Trish, sees her)
Trish: Maeve. You OK?
Maeve: No, love. I'm not.
Trish: You want me to call a doctor?
Maeve: Doctor can't help.
Newsreader: (About the Olympic torch) It's much more than a torch now. It's a beacon. It's a beacon of hope and fortitude and courage. And it's a beacon of love.
Rose: Easy for you to say, you don't have kids.
The Doctor: I was a dad once.
Rose: What did you say?
(The Doctor examining the traces of ionic energy)
The Doctor: Ha ... tickles
Tom's Dad: What's your game?
The Doctor: My um ... Snakes and Ladders ... quite good at Squash ... I'm being facetious ... there's no call for it.
The Doctor: (About the Olympics) It only seems like yesterday, a few naked Greek blokes were tossing a discus about, wrestling with each other in the sand and the crowd stood around... no, wait a minute, that was Club Med.
Rose: Feel the love.
Rose: You know what? They keep on trying to split us up, but they never ever will.
The Doctor: Never say "never ever."
Rose: Nah, we'll always be okay, you and me. Don't you reckon, Doctor?
The Doctor: Something in the air. Something coming.
The Doctor: A storm's approaching.
Chloe Webber: (said menacingly) Do you want me to draw you too, Mum?
The Doctor: I can't stress this enough. Ball-bearings you can eat. Masterpiece!

When Doctor Who Magazine conducted a poll in 2009, this story was found to be fans 192nd favorite story of the 200 broadcast at the time.
With the opening ceremonies taking place on the same day, the episode can be specifically dated to 27 July 2012.
The Dad in the wardrobe was drawn by Richard Shaun Williams, who draws storyboards for the series.
Abisola was discovered in an after school acting club. A hand double drew the pictures.
According to Doctor Who Magazine, this episode was originally called Chloe Webber Destroys The World, but the author commented that it was too long and wouldn't fit across the screen.
The final viewing figure for the BBC One airing of this episode was 7.14 million.
During this episode the Doctor mentions that he was once a father.
In the 2005 episode The Empty Child, Dr. Constantine states "I was a father and a grandfather, now I am neither. But I am still a doctor". The Doctor comments that he knows the feeling. So far the only member of the Doctor's family we know about is granddaughter Susan, who he traveled with at the start of the original series. The only other mentions of the Doctor's family were in the original series in Tomb of the Cybermen, and the 1996 TV Movie which made references to the Doctor's parents including the controversial statement that the Doctor's mother was human.
This is the first time that the 'Next Time' sequence is played without the Theme Music.
The place where the TARDIS landed between 2 containers, supposedly in Stratford, was actually storage yard by the Rhymney River off Newport Road, Cardiff
The fictional Dame Kelly Holmes Close in East London was actually a residential close in Pengam Green, Cardiff
Early dialog for this episode that mentioned the alien spacecraft was drawing out all the heat from the street. This was to explain why the actor's breath was visible in exterior scenes due to the episode being filmed in February. The dialog was cut from the final edit of the episode.
Early titles for this episode where Chloe Webber Destroys the Earth and You're a Bad Girl Chloe Webber.
Episode 11 was originally slated to be written by famed actor/ writer Stephen Fry, but his story was deemed too costly and had to be put back to series three, so Graham had to step in and write this episode on short notice (hence it was the last to be filmed). Latest reports suggest that due to a busy schedule he will no longer be writing for Doctor Who at all.
The Doctor: Keep 'em peeled.
Shaw Taylor's catchphrase at the end of each episode on 'Police 5' and 'Junior Police 5' - asking viewers to be vigilant.
The Doctor: No, I'm not really a cat person. Once you've been threatened by one in a nun's wimple, it kind of takes the joy out of it.
The Doctor is referring to episode 2.01 "New Earth" where he and Rose visited a Hospital run by Cats. He has also battled against cat people in the Classic series episode "Survival". However, in his sixth incarnation he wore a cat lapel pin.
The double fingered 'V' sign that the Doctor and Chloe exchange is the traditional Vulcan salute from the Star Trek series.
