Teasing more about season 6, Oppenheim said: “We were a few weeks intofilming, and there was absolutely no drama. I was like, ‘Oh, s—. OK, maybewe’re going to have a mellow season.’ Honestly, I was really kind of pleasedabout it. Then, some s— hit the fan just unexpectedly. So, I actually thinkthat this season’s going to have as much drama as the other seasons.”

“We were in Europe when it started to hit the fan, which was kind of nice insome ways because we didn’t have to deal with it directly, but it was also alittle bit troubling because we weren’t there to try to smooth things over,”he explained. “So, it was difficult to get through. Yeah, it was not fun tohear about, not fun to watch, but I presume it’ll be fun to watch for millionsof other people.”
