The commentaries are semi-scripted, too.

Really? I thought that they just say what comes to their mind. I mean, the commentary to IMToD was mostly dead air, with Jensen, Jared and Kim Manners being mostly silent. And them commenting about Phantom Traveler, they were all over the place, just what came to their mind. Oh well, that's just too bad. It would have been awesome *pouts*

And you're welcome ;)
