I think Jeph's intended evaluation of Faye, just like Jeph's intended evaluation of Brun and probably Bubbles, is somewhat skewed by Jeph's apparent belief that women threatening violence are inherently funny and endearing (see: all three I just mentioned).

I don't think Faye did anything wrong in the last few strips, with the possible exception of expecting Sven to automatically leave a public place because she demanded it. Neither did Tai, Dora, Marten, or indeed Sven.
