I don't think she's trying to tell us something or make a comment about the audience or her career ... I think it's just pretty plain that she feels a little .. 'subdued'?... now that it's the Power Trio and no Christine... It must feel so weird for her. Just think of all the countless shows etc she's done with Christine and now... it's just her. In terms of 'What is my role now' etcI'd imagine she's still trying to figure that out etc. As for bending down to fans I thought it was common knowledge about her hip. So I woudn't take it personally or anything.
I'm reminded of a quote from her (probably to be found on inherownwords) about how when she's on stage with FM she takes on a 'Spider' persona - more subdued etc. And the idea that she's giving Lindsey his space for recognition and fulfillment is a really nice idea.
As far as speculation on her future/career etc - she lives for her fans, her career, and getting her songs out there. She'll stop when she *has* to, cause I can't conceive her ever *wanting* to.
