The Green Death

She's off.

It feels like ages since Jo Grant came into the Doctor's life and began changing things. In those earlier stories, she quite often bears the brunt of his bad temper – and she in turn doesn't quite 'get' him. It's not until Colony in a Space that she can accept the Tardis is real, that he's not a fantasist. And to be fair, even a mad alien scientist in an Edwardian cape is a bit of a leap to one who travels  in time and space.

Perhaps it's a change of view for Jo – that scientists can be as heroic and crusading as soldiers. After all, her original ambition, facilitated by her Uncle, is to join the services – and before falling for Professor Jones, she tries dating Captain Yates. (Can't quite see that relationship going places.) Since then, she's been a humanising force on the Doctor, who has generally cheered up and calmed down. In return, she's become a woman of the universe, to the extent that she can reject the Master's hypnotism and generally talk down to him, before walking out of the Tardis doors, alone, into the alien night of Spiridon...

I still don't think she was ever quite on the same page as him though. Not like Zoe, for instance, who bravely stowed away in the Doctor's old sea-chest to discover the Universe. Jo's travels in time and space tend to be accidental and slightly reluctant. She's not fazed by them – she disputes with planetary colonists and rude-looking aliens without hesitation. Jo is always self-assured, passionate and morally certain: to coin a phrase, down-to-earth. But generally that's where she wants to be. 'There's only one little world I want to see right now,' she says, almost wearily, after all the fun on the Planet of the Daleks. 'Home.'

We're so used to show-runners' arcs these days, the original series can seem rather rackety and thrown together by comparison. But this season, beginning with The Three Doctors' liberation of the Tardis and its crew, travels rather satisfyingly to this announcement of Jo's. The Green Death is the story in which Jo Grant leaves not just the Doctor, but UNIT – and if it wasn't for Professor Jones, it might not have been such a clean break. The Doctor is clearly on the threshold of a new life away from Earth, and one feels rather certain that's not a life Jo would have joined him in.

From the Dawning of Aquarius to her stack-heeled boots and now, her passion for environmentalism, she's associated with the here and now. 'Well,' she says about the Tardis in Frontier in Space, with flippant prophecy, 'I'm never going in that thing again.'

Not that she hasn't learned from her adventures. I've reflected a couple of times on the visions of future Earth she's had: over-developed, uninhabitable, unsustainable, even ungovernable, threatened by fear and greed and waste. These are thematic connections rather than literal ones – Jo never even witnesses the ministerial self-interest that hands complete control over to Global Chemicals in Episode Two. But a lot of care has been taken with references back to Jo's arrival. Only the production team of the time and fans of today can really appreciate these: when Jo talks about her job description being 'tell the Doctor how brilliant he is,' for instance, she's quoting a line from three years earlier!

It feels a far cry from some of the 1960s seasons, where individual stories shine but the lives of the regulars – and their ongoing stories – are treated with ambivalence. The overriding feeling with the Jo Grant era, for me, is that the writers believe in the strength of their leads, in the security of this family (in part, because of the actors performances), and enjoy throwing them into new situations. In all the years I've been watching Who in sequence, this is a moment when it really feels like a series rather than a show. It would have made a perfectly fitting last story for the Master, too. As it is, it brings to an end the chronicles of that UNIT family.

What about the Doctor, though? If Jo Grant was a reluctant traveler in time and space, the Doctor has been reluctant to leave without her. After bridling so long at his confinement, it feels as if his main tie to the Earth and his main excuse for not returning to a bootless existence among the stars has been suddenly taken away – and after his solitary voyage to the fabled Metebelis 3 (has nobody ever said how brilliant that planet's name is?) he seems grateful to scramble back to Earth, to a world of mines and silly disguises and mathematical flautists called Nancy. Where exactly does he belong?

Yes, he's changed. He's at risk, you might think, of losing his Doctorishness, his capacity to transcend the present day. Yet that's exactly what his extra-terrestrial, mystical blue sapphire connotes: a very 70s sort of transcendentalism, requiring a physical bauble (whereas in the 60s they just did it, lived it, breathed it) but still effective. His conversations with BOSS, where he seems to take real pleasure in disdainfully scuppering its plans, are good to see and great to watch. And despite the coming departure of his longest ally, Pertwee seems more comfortable than ever in this scene – baiting a disembodied voice (but what a voice!).

So perhaps, he's off too. Perhaps this is just what he needs. But to where, and with whom? Who could possibly take the place of Katy Manning's consummately performed Josephine Grant...?

Scarier than any story this season, but also cosier and camper (escape in milk float to hippy commune, for example), this is a strong story by a team with real fondness for the world they've constructed - and a forlorn recognition that nothing goes on forever.

The Time Monster

In my blog last week, I talked about the unsinkable Jo Grant, and her ability to remain sunny in the continually reconfirmed knowledge that planet Earth in the future is a cosmic shithole run by total bastards. How does she remain so buoyant, I wondered, when others like myself find it hard enough to deal with an office job and the daily round of news headlines? Then this week, Jo unexpectedly crumbled.

'What happens if the Master wins?' she asks the Doctor. Chaos, he explains, on a grand scale, and it depresses Jo. 'Makes it all seem so pointless, doesn't it?' she says. Perhaps the banality of the Master's evil has hit home – the imminent catastrophe doesn't only mean death and destruction: it's a universe without meaning.

This is the prelude to the Doctor's childhood reminiscence, the story of how his blackest day was redeemed by the hermit on the mountainside, who taught him to see 'a heaven in a wild flower'; that is, the 'daisiest daisy'.

It's the first casual chat the Doctor and Jo have had since The Mind of Evil, and it's a rare moment of the Doctor dropping the 'Who' for a moment. In referring to past troubles, it recalls a fatherly moment in the tombs of planet Telos; in describing the countryside of home, it connects with a much earlier tale of burnt orange skies. We have a better sense than ever of who the Doctor is – paternal, happy in that role (he looks entirely at ease, telling stories in that prison cell), drawing on a lifelong wonder at the universe, empathy with the figure of the mountain hermit.

Here's the anchorite in his new form, perched on the side of the mountain that is our planet in a single era. Does that 'black day' he's so cagey about still threaten him? He worries at his circuitry and drinks his tea. Or reassures his friend with a story. Meanwhile, upstairs, his childhood friend is seducing Ingrid Pitt and planning the death of the actual Minotaur in order to – what?

It's not clear. The Master has a Tardis – i.e., the run of Universe – and can inveigle his way into any position he likes. He begins the story by trying to tame a god-like being from outside space and time. It does seem like an awful lot of hard work, especially given how things when he tried it last month, and that he must know the result will probably be chaos anyway, a mirror of his own megalomania. This is a story where Roger Delgado really lets rip, strutting up and down and cackling to himself. Entertainingly, but not becomingly. 

What's the nature of this madness? It's a story about messing about with time, and produces some of the most surreal and comic images of the whole series. There's capacity for exploration of some huge ideas, about how we use time and chronology to sort the Universe into order, to give our lives meaning. 'The whole of creation is very delicately balanced, Jo...' 

Or perhaps chronological narrative is a fantasy, and the Master plans to liberate himself from an illusory world into a state of naked existence. True enlightenment?

This is a sort of sequel to The Daemons. The Doctor was rather adamant in that story that science was a superior way of looking at reality, but in this story he can remotely interfere with the Master's Tardis by balancing a cup of tea on a wine bottle and making some mystical passes. The Tardis itself – pressed into use in a climactic moment that makes it suddenly seem more wonderful than it has since the 1960s – is indestructible, telepathic, illogical. The authors of this story leave us in no doubt: it's not just a spaceship – it's an idea that has somehow gained material form.

Now, The Time Monster is a bit over-extended, and sometimes the dialogue is a bit weird (like someone who's seen a lot of TV but never met a human being), but it has some amazing performances, from Dean Lerner and Miss Babs to Roger Delgado and Ingrid Pitt. It has that audacious Doctor Who spirit ('Who cares if the money's run out? We're going to have a bird-god-monster from another dimension destroy the city of Atlantis!') and the real sense of camaraderie that is unique to Jon Pertwee and Katy Manning ('Glad to have you aboard, Miss Grant.' 'Glad to be aboard, Doctor!').

And even if it doesn't really explore those ideas about time, meaning, madness, the life of the mind ('I shouldn't listen too hard to my subconscious thoughts, Jo, I'm not too proud of some of them'), it nonetheless suggests that there are two responses to the meaninglessness of existence and the daily toll of unhappy feelings. You could try and Master it, by chucking out the structure and narrative. Or you could tell a story about it. Better yet, you could throw yourself in and Doctor the story. Same mountain, different view.

There's also bags of extreme CSO. I think it really is the Pertweeiest Pertwee story.
