I'm sure Taylor is annoyed because she feels she does quite a bit of work more than Brad but wants to branch out and learn more things within the business. But I like Brad's attitude better than Taylor. I thought the first episode this season was really great! And I loved how they went to the jewelry stores to pick out pieces that would go well with each client's dress. A stylist has to really know their client really well too in terms of their style and whether they can pull off a certain look. But if you think about it many runway looks are altered to be sold to clients off the runway since many just aren't too practical to wear the way they are shown on the runway.
taylor mentioned she wants to stop styling and work on developing the rachel zoe brand, so maybe rachel will be able to transition her into a more business focused role throughout the season and then brad can be the new taylor only with a better attitude.
