Castle was the same with that accountant, asking inane questions. In classic narc traits, she cut her off mid sentance with what she wanted to say, ignored the answer and just repeated her incorrect information again.
The accountant was just looking lost the whole time, she is so narcissitic that even when she invites a guest speaker on, its all about her.
I am looking for a new accountant, however, one that is drawn into to Castle's BS would not be one I would use.
