Upon first watching, this episode was a big ball of confusing. I'd be more likely to make a duplicate recapper out of Yoplait than to make sense of it all in the space of a recaplet.
Here we go: After the original Doctor helps his ganger work out a few kinks, they couldn't be happier to be in each other's company. It's like a Christmas of adorable goofiness wrapped in two bow ties. The only way in which they differ are their shoes: The original has the brown shoes he borrowed and the duplicate has black shoes. Amy is firmly anti-duplicate, even when he goes off to rescue Always With The Rory. Rory has found what he thinks is the original Jennifer, but actually turns out to be a ganger who's growing more maniacal by the minute. She gains his sympathy by showing him a pile of discarded, melting, still-conscious gangers and then tricks him into helping her release the acid. Eventually, her murderous quest for freedom/power proves too much for even her own kind, who end up working with the originals to get rescued off the island.
They hit a few roadblocks on the way. Most of the originals get killed off in gruesome ways, like Jimmy who gets blasted with acid. As he croaks, he gives his ganger his blessing to take his place at home. Everyone seems kind of weirdly happy about this. Meanwhile, Jennifer's gone totally off the rails and has morphed into a Jennifer-headed monster. The Doctor and the Cleaves ganger volunteer to hold off the monster, but Amy protests. It's only then that the Doctors reveal that they switched shoes early on and the duplicate Amy had been so distrustful of was actually the original. They did it as some kind of... test... for Amy... or something. The Doctor and Cleaves gangers use the sonic screwdriver to melt Jennifer, even though it melts them, too.
At the end, they manage to get to the TARDIS where the Doctor stabilizes the gangers for good. Cleaves and Dicken go off to reveal the truth about the flesh and the Doctor finally reveals the truth about Amy's weird pregnancy. It turns out that the Amy we've been seeing for some time is actually a ganger. The Doctor brought them to the island so he could understand how the flesh worked. As he dissolves this copy of Amy, the original Amy's consciousness switches on somewhere in a horrific white tube, about to give birth as she's tended to by the eye-patch lady.
Stay tuned for the (hopefully more sensible) recap!
Before the short break for American viewers, we left the show with half the characters holing up in a Medieval chapel, waiting to be attacked by their gooey "ganger" clones. Things then got even more insanerer when they realized that a clone of the Doctor was in the chapel with them. "Trust me," he said, "I'm the Doctor."
We pick up this episode with the ganger Doctor screaming his head off. He's got a human face now instead of the Marilyn Manson, yogurt-based thing he had the last time we saw him. The original Doctor (well, he's the eleventh, but he's the original for our purposes) rushes over to help his ganger. The poor guy's holding his head and screaming and jerking around in agony. "One day we will get back," he says between convulsions. "Reverse the polarity of the neutron flow!" "The flesh is struggling to cope with our past regenerations," says the original. The ganger twists and flails and suddenly, in Four's voice, asks, "Would you like a Jelly Baby?" I think Ten's voice shows up in there for a bit, too. In his own voice, he asks "Why?" over and over again. The others stare in horror and confusion. Amy takes a few steps toward them but Jimmy holds her back. Ganger Doctor grabs onto Original Doctor's lapels for dear life, face twisted in agony, eyes tearing up. "Hold on, hold on," Original urges him. Ganger Doctor screams and shoves him away. His gooey face returns as he wails us into the opening credits.
While the Doctor deals with his new clone, Amy and the factory workers guard the door against the gangers. Ganger Jimmy's acid suit doesn't have sleeves, which seems to defeat the purpose of the thing. At first the gangers try breaking down the door, but that doesn't work so they retreat back down the hall to come up with a better plan. Inside the chapel, Amy is getting impatient. "Doctor, we need you! Get over here!" She doesn't even look at his doppelganger at first. The new Doctor has gotten his face under control. "Hello!" he greets Amy with a big smile. She still doesn't pay any attention to him. "I'd like more proof that you're me," Doctor O says to Doctor G. Doctor G sensibly wonders if they really have time for this, but he's outvoted by himself. While they work that out, Amy goes back to the door, which the gangers are now dissolving with acid. The originals stand back, holding small tools like clubs, like they're going to very slightly beat at the gangers while being blasted with acid. Plan of the century!
