Amy's timehead baby is born. She names her Melody Pond and promises her that her centuries-old father will come to rescue them. It sounds like she's describing the Doctor but she's talking about Rory, who had spent two thousand years protecting her as the Last Centurion. The Doctor asks him to reprise this role, complete with breastplate and sword, to trade on his fearsome reputation. The Doctor also calls in a lot of favors from all over time and space in order to mount a rescue party. Among the recruits are an awesome Silurian named Vastra and her sidekick Jenny, a lactating Sontaran who'd rather be killing people but is sentenced to healing them instead, and even those newly minted space pirates show up for a bit. Rory tries to recruit River Song, who normally springs to the Doctor's aid, but she tells him, with deep sadness, that she cannot join them until the end. It's all very mysterious.
They all head to Demon's Run, a space-based military base where Amy and the Pond spawn are being held by Madame Kovarian, formerly known as the eye-patch lady. Along with battalions of religious soldiers, some flaming-sword-wielding headless monks are defending the place. The Doctor just pops himself into the middle of all this, sneakily makes everyone disarm their weapons, and then takes over. He's really, really angry, though, so he doesn't just send everyone on their way, but also turns their general into a famous coward. Among the soldiers is a young woman named Lorna, who once met the Doctor when she was a child and only joined the army in the hopes of meeting him again. She makes Amy a bit of embroidery bearing Melody Pond's name in Lorna's native language.
Rory rescues Melody from Kovarian and everything seems to be going rather well for the Doctor. A little too well, in fact. The headless monks spring a surprise attack, killing many of the Doctor's team, including Lorna. Once Kovarian is safely far away from the Doctor, she reveals that the baby she gave Rory isn't real. Little Melody dissolves into inanimate flesh, like the gangers did last week. Melody is part Amy and Rory, but she's also part Time Lord, thanks to Amy's exposure to the TARDIS or some such. Kovarian wants to use her as a weapon against the Doctor. Only then does River show up. At first the Doctor is furious with her, but she explains the outcome of this battle couldn't have been changed. She also warns him against continuing on this way, striking fear into the hearts of his enemies and whatnot. In this future, the word "doctor" has come to mean "warrior," thanks to him. She also reveals her true identity, with a little translation help from the TARDIS. There, on Melody's embroidery, is the translated name... of River Song.
The Doctor is ecstatic and tickled and strikes off with renewed purpose to rescue Melody, leaving Rory and Amy behind on Demon's Run. Stay tuned for the full recap.
When last we saw Amy, she was about to give birth in some mysterious white tube while an eye-patch-wearing lady exhorted her to puuuussshh. Sadly, we do not get to see the infant Pond rocketing down through the tube like a fleshy pink pinball, for when we join the show again she has already been born. She is stashed away in an asteroid that has been turned into a creepy and massive military base. It is Demon's Run, because if you're going to build a creepy and massive military base, what are you going to call it? Amy, looking a bit tired and disheveled, but otherwise quite lovely, has a few moments with her daughter in a sterile white nursery. "I wish I could tell you that you'll be loved, that you'll be safe and cared for," Amy tells her. "But this isn't the time for lies." The ID on the side of the baby's bed says her name is Melody Pond. Not that there are so many babies there that they need to identify them, because she is the only one. Amy cradles Melody and tells her to be brave. The eye-patch lady waits on the edges of the nursery, flanked by armed men in military uniforms. Behind them stand monks in dark robes with hoods pulled down to obscure their identities. "Two minutes," Patch says. That she's allowing Amy any time with her baby at all is a bit odd, but it gives Amy a chance to make her inspirational speech.
She goes on to tell Melody that "they" will have to be braver, and she looks at Patch and her guards as she says this. "Because there's someone coming," she says. "I don't know where he is, or what he's doing, but trust me, he's on his way." Twenty thousand light years away, Cybermen march ploddingly through their ship. A man's hand appears out of the shadows to sonic a panel near a door. A blast rocks the ship. The Cybermen monotone that there's an intruder. In the nursery, Amy says, "There's a man who's never gonna let us down. Not even an army can get in the way." Patch takes Melody from her arms. Amy cries and pleads with her to no avail. One of the soldiers in the nursery is a young woman. She looks to be on the verge of tears.
Meanwhile, the intruder is making his way toward the Cybermen. They try to seal off each level before he can breach it, but it's useless. He gets through each one as the ship continues to shake with explosions.
Melody is placed in a futuristic contraption that looks part bassinet, part shuttlecock. "He's the last of his kind," Amy says over her baby. "He looks young but he's lived for hundreds and hundreds of years. Wherever they take you, Melody, no matter how scared you are, I promise you you will never be alone." She kisses Melody's forehead and says, "Because this man is your father."
