She has to finally realise she is out of her depth, targeting herself as a fashion account yet she couldn't think of a way to wear any of Jess's clothes in a way that would flatter her and make them individual?? Yet plenty others there did !! She has to see that she took the easy way out by wearing an old trusted dress and ripped tights, and was completely unworthy of being at the event. All those people there to show off the kollekshun and celebrate Jess ... and she is there to stomp about firing free drink in to her and clump about the hotel snaffling hot drinks in the middle of the night?!
