Wow, that sounds like an absolute clusterfuck - poor Claudia, and poor Talia too! The onscreen joke about Ivanova having left because she wanted to be paid more felt mean-spirited when I hit that point in the show even without knowing anything behind the scenes about that; there was clearly some bad blood there.

Though at the moment, I don't think I want to go any farther into discussing actors being unhappy on set - I'm sure there was plenty of turmoil behind the scenes (there had to have been, for the cast to have the amount of churn that it did) but I don't think I want to have too much of that in the back of my head when I'm rewatching the show.
