Isaiah Washington & T.R. Knight's BTS Drama Explained By Crew

"[N]ow, i should say that there is no excuse to say that word to anyone at anytime, but context should be taken into account," this former crew member continued. "Patrick was the one who got into it with Isaiah, not TR, because I think TR initially knew he was just being as ignorant and stupid as he normally was."

The bottom line, this person seems to say, is that hours were long, emotions were running high, and Isaiah Washington said something hurtful and stupid without thinking. Unfortunately, because of the obviously sensitive nature of the subject, nobody reacted well, to say the least; in fact, the reaction made everything that much worse. "Patrick got righteously indignant about it and made it much worse than it was in actuality," they revealed. "This wasn't the first or last time something of that nature elicited that kind of reaction from him." 

Later in the thread, they clarified that Patrick Dempsey isn't an angry person, just reactionary, and that yes, the environment was different after all of this went down. Apparently, paparazzi showed up and there was strife on the set even before they arrived. But also, everyone was there to do their job, and they did the best they could under the circumstances.
