Hannah Maynard (Rosalind Wilson) is a green young WPC, temporarily seconded to Hartley. She’s keen, very keen, but quickly learns that there’s a wide gulf between theory and practice ….

Expectations, like a number of other episodes, juggles several plotlines. The slightly testy relationship between Tom and Jean is teased out in the opening few minutes. At present he’s got an even heavier workload than she has (Tom tells her that he’ll need to work this weekend). His desire to make a success of his new career in Social Services is clear, but so is the feeling that everything’s starting to slip away from him.

His office is a glimpse into the long vanished, pre computer age. Apart from whispered conversations and ringing phones, the only sound is the gentle click clack of manual typewriters. With no computers available to store or collate data, it means that everything has to be written down – hence why everybody is drowning in reams of paperwork.

There are several examples of this – a message from Jean on Tom’s desk (reminding him about their lunch date) becomes buried under a bunch of files whilst his fumbling with more files during a case conference draws expressions of disapproval from some of the others present.

Tom’s current case concerns Laura Cartwright (Jean Rimmer) and her husband Jack. He’s confined to a wheelchair, but this doesn’t prevent him from lashing out viciously at her. Laura later tells Tom that she allows Jack to hit her for the simple reason that if he didn’t attack her then he might do something to himself. A bleak moment with no closure, it’s another of those well-mounted kitchen sink drama scenes that the series excelled at.

It’s interesting that despite this being a major plot point, it isn’t a police matter (they aren’t involved at all) and indeed the travails of Laura and Jack are somewhat secondary to the examination of Tom’s working practices. His desire to prove himself has led him to take on more and more cases (since he believed that refusing any would be a signal that he wasn’t up to the job).

With Tom’s colleague, the ever patient Jennie Randall (Wendy Allnutt), also present, Laura directs a diatribe at poor Tom – describing how his visits are perfunctory at best and useless at worst. She may be being a little hard on him, but for a man who’s always prided himself on his ability to work with people (and joined the Social Services in order to make a difference) it’s something of a hammer blow.

Whilst this is going on, Jean welcomes WPC Maynard to the team. She clearly heroine worships Jean – confirmed by the fact that she requested a secondment to Hartley precisely because she wanted to serve under an officer whom she admired. Jean isn’t especially delighted to hear this and gently tries to explain to Hannah that the job is the important thing, not personalities. It’s left unspoken, but there’s the inference that it’s rare to ever be in a position to pick your superiors (we’ve seen how the likes of Superintendent Lake are – at best – rather condescending towards Jean). Rosalind Wilson is excellent as the keen as mustard Hannah, who manages to exasperate the phlegmatic Roland with her attention to detail.

Youth culture isn’t something that the series has tackled so far, but today we see two punky teenagers – Mo (Clare Toeman) and Laura (Sarah Sugarman) – which proves that Hartley does have its share of disaffected adolescents. They mooch around the perimeters of the plot for a while – trying the doors of locked cars on a grimy housing estate, running through a bleak concrete shopping centre – before they come face to face with Hannah.

Left to her own devices by Roland for thirty minutes, it’s plain that she’s no match for Mo and Laura. The pair, apprehended for shoplifting, are marched to the manager’s office – but when he has to leave, Hannah is left alone with them, which is where the trouble starts. The manager locks them in – a strange move since it means that once the punky pair turn on her, Hannah has nowhere to run.

The sight of a dishevelled Hannah, “pig” written across her forehead, slowly walking through the store (with an amazed Jean looking on) is a memorable one. Hannah’s reason for not cleaning herself up first – she wanted to public to see the dishevelled, other side of police work – is given short shrift by Jean. She considers this to be a highly melodramatic way of proving a point.

If the title of the episode could easily relate to Hannah’s experience, then equally it fits Tom’s nightmare of a day. The episode ends as it began, in the bedroom, although this time Tom is in a reflective mood. “I was incompetent and irresponsible” he tells Jean. His long suppressed resentment of her more successful career also bubbles to the surface but as they settle down for the night, there’s the sense that they’ve turned a corner and more positive times lie ahead.
