Constantine's getting a guardian angel for his TV series... literally

The cast of NBC's Constantine TV series has expanded, and now we know three new characters who will team up with, be annoyed by and invariably regret knowing the titular magician. And that includes an actual angel played by a former Lost castaway.

The new cast members include Harold Perrineau, True Blood's Lucy Griffiths, and Charles Halford, most recently seen as the very unpleasant Reggie LeDoux on True Detective. Here's the character descriptions from Deadline:

When Liv (Griffiths), the daughter of a late friend, is targeted by demons, Constantine steps in to save her. Griffiths' Liv is an offbeat young woman tired of her ordinary life who comes to discover that she has the ability of seeing the supernatural world among us, which makes her a key player in the battle between good and evil. Liv teams up with Constantine to save lives, master her power, and learn more about her late father.

Perrineau will play Manny, an authoritative angel assigned to watch over Constantine who has the power to step into other people's bodies, and although he is meant only to observe, Manny will not hesitate to help out if he can save a life.

Halford will play Chas, Constantine's oldest friend and staunch companion who possesses powerful survival skills that might possibly be supernatural.

I don't think this is bad, just odd. I'm used to Constantine being an inveterate loner, mostly because he's an unrepentant asshole and no one can stand to be around him for more than a few minutes. But a TV series obviously needs to give him some actual pals, because otherwise the show would just be 45 minutes of Constantine smoking and drinking.
