Well I have long figured that Anette's pregnancy was discovered during the Denver hospitalization and that necessitated sending her home early. At 40 years of age, it would be easy for her to lose the baby, so she had to get off the road ahead of schedule. I think the whole "cyst on her liver" diagnosis was cover for it, because again, she didn't want to say too early she was pregnant because she could lose the baby early on. And Tuomas just gave her cover. The statement they issued on her dismissal was the statement they planned to use for when she would quit post-Hartwell, they never bothered to rewrite it to say she was pregnant.
I'm still waiting to hear some kind of comment from Tuomas or the band. Have they said anything?
