WARNING: This blog is for people watching "The Hour" on Wednesday nights on BBC2. Don't read ahead if you haven't watched it yet - contains spoilers!

Catch up on last week's instalment here [2]

This was a morality tale. In fact, because this is The Hour and nothing is ever straightforward, it was several morality tales at the same time. You could take your pick, really: fascists and free speech; pornography and corruption; innocence and loyalty - this episode had it all.

The main business of this episode was Hector’s spectacular fall after his drunken, lecherous pride. He ends up languishing in a cell after being (wrongfully) accused of beating up a Soho callgirl. The use of contrast here was superb – at the start, he’s the bumptious dinner party host, swilling down cocktails and rolling his eyes at his wife. Twenty minutes later, we see him in a police interview, hands shaking so much he can’t even put a cigarette between his lips.

The breakout performance of this episode was undoubtedly Oona Chaplin as Hector’s long-suffering wife, Marnie. Rather than dash straight down to the police station to try and exonerate him, she suddenly finds a spine and spends the night on her own at home before successfully auditioning for some producers to get her own cookery show. It’s a delicious bit of plotting – not only has Hector been humiliated by his arrest, he’s now not even the most popular television personality in his own house. When she does finally turn up to take him home, it’s a different Marnie wrapped in that expensive fur coat. No more will she put up and shut up with Hector’s antics – she’s going to drive the car if she wants to, while firmly telling him that theirs is now a marriage for appearances only. I look forward to Marnie discovering feminism next week, taking a lover who actually likes her, and finally giving Hector the boot.

As I mentioned last week, The Hour has really struck lucky when it comes to its scheduling. The news agenda might have moved on now from the perpetual “BBC in crisis” stuff of ten days ago, but when Anna Chancellor’s Lix declares exasperatedly “Is this what we have to look forward to? Continuous controversy?” you can’t help feeling she’s on to something.

The controversy she refers to is Freddie’s determination to interview a fascist on The Hour. The debate the programme’s journalists have about it is strikingly similar to the arguments made when BNP leader Nick Griffin appeared on the BBC’s Question Time in 2009 [3] – Bel and Hector feel its “playing into Mosley’s hands to let them join the debate”, while Freddie thinks they shouldn’t patronise their viewers, and rather “give him the rope to hang himself if he wants”. In an example of how The Hour rather neatly blends the personal drama with the political storylines, the fascist Freddie interviews just so happens to be the one that’s been terrorising his wife, and the “immigrant” who gives the other side of the story is Hour secretary Sissy’s boyfriend, and Freddie’s lodger. The latter, Sey Ola (whose struggle between love of freedom and hatred of his persecutors is portrayed brilliantly by Adetomiwa Edun) eventually delivers the standout speech of the episode – telling Freddie that it’s because the fascists have the freedom to say such hateful things about him that he knows British democracy is strong, and that it’s where he wants to make his home. Next time someone makes the “no platform” argument, I think they should be required to watch that clip and reconsider their position.

After a slightly whiney start last week, this was a good episode for Romola Garai’s Bel. She did some serious investigating of the Soho pornography scene, flirted extensively with her opposite number on ITV’s Uncovered (who turns out to be a widower who can be prevailed upon to bring her chips late at night), and makes friends with Freddie again – most of which she achieves while wearing a very clinging and extremely attractive emerald green cocktail dress. This excellent little snippet of dialogue gives me hope too that Abi Morgan has plans for the future of Bel and Freddie’s complicated relationship:

“Where have you been?”                                                                                    

“Buying pornography. You?                                                                              

“Picking up fascists.”                                                                                    

“Marvellous.”                                                                                                             

A slightly more disappointing aspect of this week's episode was the readiness with which the woman accusing Hector revealed her real motive - she was actually trying to punish her lover, the deputy commissioner of police, the stern-jawed Commander Stern. His corruption notwithstanding, I felt as if we should have had to guess at that for at least another episode, but perhaps it was important to reveal it now in order to facilitate greater plot machinations in the future. The jury's out on this one.

Incidentally, my prayers for more of Ben Whishaw and less of his beard were answered this week. We even got to see him, clean-shaven, do the journalistic equivalent of shadow-boxing, practicing his presenting skills on invisible interviewees. Lovely stuff, although his French wife is starting to grate slightly. For the second time in two episodes she appeared mostly on screen wearing just her knickers and an over-large jumper. I think this is supposed to tell us that she is “bohemian”, compared to the English women who keep their stockings on at all times.

Another interesting revelation this week – Peter Capaldi can do sex appeal. His languid, drawled “You’re wearing a cocktail dress - have I missed the party?” and Bel’s blushing reaction perhaps sets up an intriguing new relationship, although I must admit I’d much rather see more of him arguing with Anna Chancellor.

Chancellor remains, for me, the best actor in this thing, and she also delivered the line that neatly wrapped all the morality tales together:

“Heroes or villains, we’re all somewhere in between. The good do bad things and the bad are sometimes kind to their mothers.”

Meanwhile, a newly-liberated Hector returns to his favourite Soho haunt and demands a table "at the front - I've got nothing to hide."

So, the moral of the story? Nobody ever learns their lesson.
