Supernaturalsupcoming 300th episodeisnt only bringingJohn Winchester back.

I was told I was going to read for [Supernatural], and it was a good guy.

He seemed like a very nice guy.

I was quite upset about it.

And Im thinking theyre gonna make me a regular.

Im going to finally get on theSupernaturalgravy train which has been running down the track.

Unfortunately, we need a big event for our hundredth episode, so were going to kill you.

And then I go, Yeah, youre going to kill me, but nobody ever really dies onSupernatural.

And they said, Well, no, youre getting killed with an angel blade and your wings burn.

I said, Well, what does that mean?

If your wings burn, you dont come back.

And the knife goes up through your mouth into your brain.

I go, Okay, Im dead-dead.

I wasnt expecting anything.

I go, 300th episode?

And I said, Sure Id do it, are you kidding me?

So they wrote it, and here I am, happy to do it.

He thinks hes hilarious, he thinks hes charming.

He can fix everything.

But he doesnt have to be mean, he doesnt want to.

He really wants to just have people laugh with him and go, You know what?

Youre right, Ill do that.

Okay, lets go have a drink.

But it usually ends up with a lot of blood and a lot of death.

Did you have to do anything to remind yourself of what you did 200 episodes ago?

Did you watch old episodes?I didnt have very much time because I was working on something else.

But the show, it has really changed.

Theyre not doing the same thing every week.

Its really very compelling.

I was so struck by the sense of loss in [the 300th] episode.

I think thats the most compelling thing about the show.

It is classic Zachariah.

He hasnt changed or grown, or had any experiences.

It is fun, and hes still clever and up to his old tricks.

Youre not gonna hang around being that bad.

They are brothers in life.

It is their relationship in the show, which is informed by their relationship not on the show.

Its their chemistry and their shared experience that is really compelling.

One truly cares about them and feels for them.

Like I said, [Sam and Deans] lives, theyre tragic.

Theres a tragedy there along with everything else.

Along with them being the heroes, theres a real sadness underlying it.

People can handle it.
