From the Eclipse Magazine interview with Misha Collins:

I asked Collins if he thought that over the course of time, Castiel might become influenced by Dean in any way or if Castiel will have more influence over Dean.

“I don’t really know where this is going,” he says of the ongoing story arc. “but I do know that Castiel begins to understand humans more as time progresses and I definitely think that he develops a real respect for Dean.”

So I asked Misha Collins some hard-hitting questions looking for more in-depth spoilers to share with Eclipse readers.

Does that mean that Castiel might suddenly acquire an addiction to pie?

“To be honest, I’m not yet sure Castiel eats at all. He may be anorexic.”

Did he think that Dean and Castiel might become buddies enough that Dean would let the angel drive the Impala?

“I don’t think they give out driver’s licenses in heaven.”

It was obvious that even angels live in fear of ‘the Kripke’ when it came to divulging spoilers. However I did get one thing out of Misha Collins. Apparently Castiel’s favorite music is Rachmaninov’s Vespers. Somehow I’m thinking that’s not gonna go over too well with Dean Winchester if Castiel tries to pipe that through the Impala’s speakers!

And finally:

One last thing I was most curious about was would Castiel be getting a wardrobe change or will he continue to dress like a ‘holy tax accountant’?

“Kripke wanted to base the look of the character on the comic book character ‘Constantine’ I don’t know if I’m ever going to change clothes. Maybe they will eventually be worn to tatters and I will morph from “holy tax accountant” to “holy homeless guy.”

Kripke wanted to base the look of the character on the comic book character ‘Constantine’

Ooh, nice to get confirmation on that.

And...dammit, Wikipedia informs me that it's actually pronounced "ConstanTINE," not "ConstanTEEN."

Sumi, that article you posted a link to on Wincest is an awesomely interesting read. Thanks for that, as well as the Misha-Castiel stuff.

Who do we think made the mistake, the person writing the interview or Misha?

Well, the person writing the interview seemed to have only the most passing acquaintance with spelling, and evidently was not on speaking terms with dictionaries. ijs.

Maybe they will eventually be worn to tatters and I will morph from “holy tax accountant” to “holy homeless guy.”

I like this guy!

Don't they all pronounce it Constan-TEEN in the movie, though?

Misha sounds like he fits right in, doesn't he? ::dreams of the day he does a con with the boys::

Well, the movie does turn him into a dark-haired American hottie, rather than a scruffy blond Scouser, so pronunciation not so much true to the original text. Guess you can pick your canon!

(Although I liked the movie, and loved Gabriel. Gah. Hotness. Still, I'm sorry that they'll never make a movie of the comic now, because I love the fact that he's a blue collar Liverpudlian, and that so many of his stories are set in Thatcher's Britain. It's such a very unAmerican fantasy, and such a very unHarryPotter take on English fantasy [cue reiteration of how fabulous Gaiman's Books of Magic is. Although not so much the nonGaiman spinoffs.])

Books of Magic came out a bit before the first Harry Potter novel, didn't it? I remember being struck by how very much Harry resembled Tim Hunter when I first became aware of the series. Down to the owl.

To be fair, Books of Magic didn't invent the archetype of the dark-haired, bespectacled boy who gains or discovers he has powers. But there's definitely a resemblance.

Yeah, I think Neil Gaiman mentioned that in his blog once.

And he basically said this.
