"The Star Beast"
- The Doctor sneaks into the steel factory where the alien spacecraft crashed despite UNIT having the place under lockdown.
- The Doctor takes note of several discrepancies about the Meep's story vs the Wrarth Warriors' actions and realizes that something doesn't add up. After finding a safe spot, he intercepts a teleport for the Wrarth Warriors, invokes the Shadow Proclamation, and exposes the Meep as the Sole Survivor of a species of insane war-mongers. All while wearing a judge's wig, because of course he did. This causes the Meep to abandon their cute and cuddly façade because their cover's just been blown to smithereens.
- Donna took the lottery winnings, to the tune of £166 million, and, aside from buying a home for her family, gave every last penny to charity because there were people in the world who needed it more than her. Of course once she gets the her memories back, the first thing she does is rail at the Doctor over this decision.
- The DoctorDonna returns and in less than a minute, 55 seconds to be exact, manages to reverse the Meep's engines (while repairing the damage it already caused in the process). She caps it all with this Call-Back to earlier in the episode:Donna: [To Rose] I would burn down the world for you, darling. Anyone has a go, I will be there, and I will descend.DoctorDonna: Best 55 seconds of my life because I get to do this! [Flips several starting a chain reaction of Explosive Instrumentation.] Donna Noble is descending!
"Wild Blue Yonder"
- The unnamed alien captain, three years prior to the story, outfoxed the Not-Things by setting a three-year self-destruct countdown on her marooned ship, to be triggered by a non-organic robot that the Not-Things couldn't read, before stepping out of the airlock so the Not-Things couldn't copy her and take over the ship. All while remaining "as calm as a Zen Master", to slow down the Not-Things as much as she could.
- The Doctor shows that he figured out he picked the wrong Donna just a few seconds after the fact by telling the Not-Donna "Your arms are too long.", then flinging her out of the TARDIS and letting the real Donna on.
- The fact that we get to see the Doctor reunite with Wilfred Mott, over a decade after they last saw each other. Also very much a Heartwarming moment.
"The Giggle"
- UNIT is firmly back and better than ever, with an Avengers-style tower as headquarters, tons of people/resources, and former companions like Mel and Donna amongst their employ.
- Donna in particular, after being offered a position by Kate, shoots for the moon by asking for double pay and five weeks holiday, and receives it on the spot, no questions asked. This is the kind of pull being a friend of the Doctor gets you!
- Bonnie Langford shows off her singing skills by perfectly replicating the notes of The Giggle.
- UNIT needs to take down a South Korean satellite in orbit but can't without permission or it could cause an international incident. They can't get permission because all the world leaders are affected by the Giggle, so the Doctor gives them permission on his authority.
- Donna walks into a room in the Toymaker's realm and hears a crying woman. Rather than check up on her, she shows how Genre Savvy she has become on her journeys with the Doctor by immediately cottoning on to the fact it's a trick, and threatens to kill the crying person. When the Wounded Gazelle Gambit is revealed in short course, she wastes no time making good on her promise - see below.
- Donna gets attacked by Stooky Bill's rhyming, flesh-eating puppet family. She promptly turns the tables with a rhyme of her own.Donna: Hello, Stooky. / My name's Donna. / Now I think that you're a goner. [batters Stooky Sue against the wall with enough force to literally knock her block off]
- The Toymaker gets a villainous MOA for his showstopping, Reality Warper rampage though UNIT, dancing up a storm to the Spice Girls and effortlessly killing off any guards who try to stop him.
- As horrifying as it is, the fact that the Toymaker not only outsmarted and imprisoned the Master, but the White and Black Guardians and God as well is a hell of a way to establish him as one of the most powerful beings to appear on the show.
- What happens when the Fourteenth Doctor is shot by the Toymaker's Galvanic Beam and starts to regenerate? Donna and Mel defiantly walk over to the Doctor, declaring to the Toymaker that they will be by the Doctor's side during his regeneration, despite having a deadly weapon aimed at them.
- After the bi-generation, the Fourteenth and Fifteenth Doctor effortlessly fall in sync to defeat The Toymaker through a game of catch. The Doctor(s) win not with a complicated plan, but skill at playing a simple game.
- Due to the rules of the Toymaker's game, both Doctors get a prize. The Fourteenth Doctor's prize? The banishment of the Toymaker from reality, forever. The Fifteenth Doctor's? Using the residual time the world's in the state of play to double up the TARDIS using the Toymaker's mallet.
