A disco/party with those odd flashing lights – Cassie saunters merrily over to the bar, and orders a pint of lager. Thelma would be proud. Cassie then proceeds to (accidentally) tip the drink on a boy next to her, who proceeds to try flirting with her, then slithers off in his cloak of darkness after she scorns him.

Another guy, from Cassie's media class, tries to chat her up by displaying his knowledge of the Alien films. I'm sure it's the writers' attempt to add a little bit of the metaphorical into the show, but Cassie is more interested in following the slithering lager boy after Azazeal pops up on the dance floor. Cassie then proceeds to squirt the lager boy in the face with CO2, and electrocute him. After he has had a fit and tried to rape a girl, of course. Maybe it would have been easier with a stake?

The room of gloom - Cassie cries while looking at Thelma's bed. Cut to a 'dream' scene, with Cassie and Thelma making out. In their underwear. With soft lighting. When Cassie wakes up, she sees Thelma sitting attentively by her bed, and accuses her of 'stalking' her dreams. Thelma claims that she wasn't complaining in her dream, and Cassie whines that she looked like a "whore" in cherry-covered panties and bra. Thelma and Cassie then walk (unfortunately fully-clothed) across the school grounds, talking about Azazeal. It's still rather mysterious and confusing, and Thelma profoundly states that "..he's a man. They never make sense."

Cassie takes this advice to heart, and walks past Troy's car in her tea cosey hat. He asks her for help with his stranded car, she tells him that it sounds like he has a flooded engine. Troy attempts to woo Cassie with his heated seats, and they have coffee. (Outside a café, not in the car.) Thelma, your friendly neighbourhood ghost, unsubtly spies on her and Troy, who is moaning on about the idiocy of Leon.

The gothic, gloomy, (and, er, dark) school grounds - Azazeal smokes a cigarette, while looking wistfully at a lit window. You expect Michael Jackson to jump out from behind and do "Thriller" with him.

The girl's bathroom - Thelma and Cassie continue their flirtatious bickering, while Thelma goes through Cassie's makeup, and Cassie tells her off for spying on her. When Thelma finds a condom in Cassie's bag, Thelma comments sardonically "you have to try everything once," causing a reaction of mock-horror from Cassie. Then Cassie nearly gets strangled by a strange little blond girl.

Que the compulsory shower shot, where Thelma is now staring at Cassie's, er, assets. Cassie chews her out:

Roxanne and Gemma then enter the bathroom, talking about Roxanne's latest sex dream, which apparently left her feeling "dirty," as it involved girl-on-girl action. When Gemma (and Cassie, still in the shower) learn that the girl who was "just using me [Roxanne] for sex... and I enjoyed it" was Thelma, Cassie looks meaningfully at the still-present Thelma, who retaliates with "What? Do you know how frustrating it is to be a lesbian ghost?"

Which leads the audience to ask, do you know how frustrating it is to watch a lesbian ghost?

The garden of mist and foreboding - Azazeal churns out old favourites like 'you can't fight me', 'death is inevitable', 'history has a habit of repeating itself', and other vague comments, while saying how similar Cassie's soul is to his. As long as she doesn't turn into a green monster with wings, I'm happy.

The common room - Leon questions Gemma and Roxanne about whether they think that Cassie and Thelma slept together, and which one was "the man", obviously attempting to reference 'roles', rather than gender. Troy looks anguished with his pool cue, follows the retreating Cassie, and asks her out. She surprisingly says no.

The Grounds - Cassie watches Troy play football in one of those silly bibs. Thelma joins her, exclaiming:

The dorm room - Cassie dreams about what Azazeal said. He watches her, while stroking some material of her's on her chair. I preferred Thelma's dream.

The favourite filming spot (aka the grounds) - Cassie is showing off her ugly hat again. The female teacher (who practically hit on her in the first episode) joins her, and pesters Cassie about bunking off, or not letting people in. Or both. Thelma pops up and tells Cassie to cry more, or to try self-mutilation. Thelma then proceeds to let Cassie into the secret that the teacher writes poor erotic fiction in her spare time.

This school is officially hormone-centre.

The duo then find a tomb underneath the tree where the scary kid was hung from, which confirms her to be Rachel McBain's daughter (he woman who conjured up Azazeal in the first place).

The dining room - Thelma tries to solve the mystery, and does so by eating a packet of crisps while staring at McBain's portrait. By her amazing instinct (Jemima Rooper was in The Famous Five, you know), she stumbles upon the room she was murdered in, which turns out to be the place where the child was locked. The room is covered with exorcist-like drawings of Azazeal, hidden under canvas sheets.

The Garden of Mystery - Cassie is obviously not as impressed with Thelma's discoveries as she is entranced with Troy being boyish with Leon.

Back in the dining room - The Erotic Fiction Teacher (Miss Joe Wilkins) flirts with the headmaster, while talking about Cassie and Cassie's "fruit-cake" of a mother. Oh, and, sausages.

In Miss Wilkins' class - Gemma reads an 'erotic' passage by Yeats of Zeus raping Leila. Cassie looks wistfully at Troy, and then arranges to have a drink with him after class. From swans to drinks – the teenage trail of thought is obviously not meant to be understood.

In the common room - Thelma boasts about how she can eat as much as she likes without putting on a pound. Cassie confesses to having a date with "golden balls" (as Thelma names him), and then goes off to get coffee, leaving Thelma to see that Cassie has drawn the same images that were on the wall of the little girl's room, all over her homework. Thelma looks worried, either by the developing explanation of Azazeal's "history has a habit of repeating itself," or by Cassie's drawing skills.

In their bedroom, Thelma completes her fairy-godmother like status by wearing a big, black tiara, and telling Cassie to "look after yourself", while then staring sadly from the entrance of the school. Thelma then troops around the school, getting inspired by smudged writing on classroom boards. With torch in mouth, Thelma checks out Cassie's record in a very un-Nancy Drew like manner, finding out that Cassie's father is called James McBain, the same surname as the crazy people.

Meanwhile, Troy and Cassie play pool in the disco place (is that all Troy can do, play pool?) with Azazeal looking on, brooding (for a change).

Next Week: Where on earth with the mystery go next? Will Troy ever stop playing pool? And, why does Thelma seem to pay for sweets and dig up earth, but not be able to touch human form? These questions will keep us entranced until next week, I'm sure.
