Acceptable Targets: "We do an Elemental Transference, like we did with Keith Richards." Once again, the supernatural is the only logical explanation for Keith Richards' longevity.
Angst? What Angst?: Jack reacts with just a little more sadness he gets when dumped by Alyssa when his grandfather, his only family left, dies. One would expect a tad more of a reaction to that or at least a bigger amount of anger towards Edward for killing him. That said, Pop's death does throw Jack into a rage-fueled Heroic BSoD.
Cliché Storm: The show is more or less your average YA Urban Fantasy story, uses tropes and archetypes that have already been done many times, especially on the mid-2000. Some fans really don't mind it, finding that show comfortably familiar.
Complete Monster: Edward Coventry, despite his charismatic and affable nature, is really an ambitious sorcerer willing to do anything to gain ultimate power. As leader of the Hermetic Order of the Blue Rose, Edward used his own members as he saw fit, treating them like disposable pawns in order to achieve his goals. When Edward learns that he may be able to construct the Vade Maecum Infernal and earn god-like powers, he forces the Order to focus solely on finding the book's pages, ignoring how dangerous it could be to create such a book. He has the Order sacrifice a group of civilians; instructs one of his minions to kidnap innocent people so he can turn them into monsters capable of destroying the Knights of Saint Christopher; and attempts to cajole his youngest son into being a sacrifice, similar to his wife. When Vera becomes wary of Edward's plans, he commands Alyssa to murder her just so she can't stop his schemes. Later on, after Edward is nearly finished completing the book, he tries to kill Jack Morton, his other son, and threatens to torture Alyssa if she doesn't watch despite her consistent loyalty to him.
He Really Can Act: Louriza Tronco, playing Gabrielle Dupres, gets to show a ton of range in Season Two, starting with playing Randall-glamoured-to-look-like-Gabrielle, then finally Midnight-possessing-Gabrielle, and in between getting one of the season's meatier character arcs with lots of Hidden Depths and Character Development. Not bad for what was, in Season One, a one-note spoiled princess Rich Bitch.
Ho Yay: In spades. Aside from Lilith being canonically bisexual, Randall has a lot of these moments. He gets a lot of shirtless scenes (that he himself doesn't need to have) with Jack, which Jack himself lampshades. Hamish comments on the difficulties of dating a fellow Knight, Jack asks if it's Lilith or Randall, and Hamish replies "No and he wishes." Season two gives us a scene where Hamish and Randall kiss to throw off suspicion from themselves, and they seem a bit more willing to do it than normally hetero guys would be. When Lilith gets dragged to Hell, Randall cries into Hamish's arm, and Hamish rests his head onto Randall's in response. They're really trying to lay it on thick at this point. Also, Alyssa lists off her previous relationships, and notes "Shelley was just a fling." No further detail is provided, so it could go either way.
Visual Effects of Awesome: In Season One, the werewolves are shown very sparingly, with lots of camera tricks to avert Special Effects Failure, though when you can see them, they look damn good. Season Two shows them a bit more often, though still refusing to let the camera linger too long. They're still probably the best-looking CGI werewolves ever, and you can pick out individual details: Tundra has white fur and a scar over his right eye, Greybeard is dark brown with a grey patch of fur on his chin, Midnight is almost entirely black and covered in scars (probably symbolic of his history of self-sacrifice), Timber has the coloring of a timber wolf, and Silverback is darkly-colored but with a gray patch on his back.
