Getting back to the original topic, I suspect Kellie was likely stunned and personally crushed by the words in the article, as I personally doubt she had any idea whatsoever that Lou was hurting on so many levels. That said, unless Lou is an Academy Award-level actress, it does seem odd that NOONE saw through her performance. And yes, the staff had a lot on their plates and maybe, in their minds, Lou with her maturity and great attitude put her on their "don't have to worry about this one" list, but still...
I hope that one day we'll read that the staff got together with Lou and worked it out, and that it was truly all just a terrible lack of communication that had actually come from a place of confidence in Lou instead of dismissiveness of Lou.
