Down to Wendy Crick?
I don't think so.
What if she did have it in for Emerald? She would still have to find something tangible to pin her prejudices on.
She may have had something to do with the demise of Emerald but if a certain CEO had not treated the CAA with the same arrogance and disdain that he treated staff and customers alike, I think Emerald would still be flying.
Wendy crick may have fired the bullets (and I don't know, not having worked for the Mobster for many a year), but if Mr "everybody but me is a w**ker" hadn't actually had them delivered to her by courier things may have been different.
One person, and one person alone was responsible for Emerald's demise.
