I seem to recall this article having been posted on the rumors board a few weeks back (give or take).
It's definitely interesting to hear some of the "reality" that this CM saw, but at the same time, it's hard to believe how he blatantly broke rules here and there with seemingly no remorse. Don't get me wrong, I can see situations arising (especially with some of the visitors) where some degree of liberty in ad-libbing might necessarily stray beyond the normal guidelines, but I don't think there's any excuse for things like "Say Rum". I wouldn't consider it a big deal, personally, but it's definitely willful defiance.
I wonder if things like what was described have anything to do with why Captain Jack is such a specifically limited character?
