@Shapeless,
I suspect they encourage that kind of talk in those interview segments. Ivy seems more than willing to comply. She doesn't appear to be that bitchy in the workroom.
After thinking about that last show, I think the judges were really egging the losing team on to act exactly the way they acted. Then they appeared all offended when they actually did. Who knows how anybody who is sleep deprived and under pressure would have acted. Gretchen, however, refused to take the medicine when Tim handed it out. She is manipulative. The rest of them seemed to take his lecture to heart.
I hope they all get back on track and forget about all of this manufactured human drama.
