"I've reversed the Jelly Baby of the neutron flow....."
Part Two of this story brings double trouble for the Gangers as the Doctor now has his own duplicate and, unlike most previous multiple-Doctor meetings, they get on famously. No snide comments about his effectiveness being halved this time: the two Docs have a ball, finishing off each other's sentences, complimenting themselves on their cool taste in bow ties etc. And we also get a lovely little nod to past Doctors:
"The Flesh is struggling to cope with our previous regenerations....."
As the Ganger Doc tries to stabilise his Flesh-y form he blurts out lines from past incarnations and presents us with the startling sound of Tom Baker's voice coming out of Matt Smith's mouth! And also a mention of Cybermats. Foreshadowing future stories here...?
Back at the plot, the Gangers are starting to have second thoughts about their "war" with the humans, and everyone is desperate to escape the island as the threat of acid, poison gas and a final, fatal explosion escalates. The Jimmy Ganger is manipulated by the Doctor into speaking to "his" son via holo-phone, further strengthening his empathy with humans. Jennifer, however, pushes on with her campaign, tricking a more-than-usually gullible Rory and manifesting more icky powers such as growing eyes on the monastery walls to act as CCTV.
Amongst the running around in corridors, a confused Amy confronts the Ganger Doctor and reveals to him that she's possibly seen his death in the future. Of course, the two Docs have switched places and now the "real" Doctor knows his Terrible Fate. Before this can be explored any further Jennifer turns into a stretchy, CGI monstrosity, the Ganger versions of Cleaves and the Doctor sacrifice themselves to defeat her, and the survivors are whisked away in the Tardis. "Jimmy" is reunited with his son, whilst Cleaves and Dicken ( the one acid factory employee who was "almost" totally inconsequential ) are dropped off at the HQ of their evil corporate masters in the ( probably vain ) hopes of alerting the world to the horrors of Ganger slavery. But the real climax of the story is ( like in the Tenth Doctor's Utopia ) a cliffhanger that points the way to the next story and turns out to be far more important than the episode preceding it:
"I said 'breathe', Pond. Remember? Well, breathe....."
In the Tardis Amy is (SPOILERS! ) having contractions and about to give birth. And she looks so thin! In the big revelation of this first half of the series we learn that the Amy who's been running around and having adventures for possibly the last six episodes was in fact a ( SPOILERS! ) Ganger and the Doctor's trip to the monastery wasn't random but was a fact-finding mission. Except "stuff" and "shenanigans" got in the way.....
"We're coming for you, I swear it. Whatever happens, however hard, however far we'll find you."
"I'm right here....."
"No you're not. You haven't been here for a long, long time."
The Doctor promptly melts the Amy Ganger, severing its connection to the real Amy who, we discover, is in the clutches of Eye-Patch Woman ( scariest midwife ever? ) and is "ready to pop".....
Phew! It's a traumatic, shocking cliffhanger which prompts re-evaluation of the entire series so far. Has Amy been missing since the end of A Christmas Carol ? ( As hinted at by exec. producer Beth Willis on this week's DW Confidential ) Or was she switched with her Ganger by the Silence? And what of the little girl, last seen "regenerating" in a New York back alley? Is she Amy's child or something else? The real problem with this turn of events is that, for all the Doctor's talk of doing things the humane way, he has just effectively killed a Ganger. And, as my learned colleague Mr. Steve W says here, this undermines all the Doctor has learned about the Gangers being "real" people. Anyway, a harder edge is sure to come in handy for the Doctor soon, even if it's morally suspect
( shades of the Sixth Doctor! ), as he races to find Amy, and a good man goes to war.....
