Yeah, indeed it was. It's what makes House such an interesting show and character. I mean our "hero" is a grade-a asshole!
Wilson didn't know about her actual motives when they went to dinner, iirc. And when House deduced what she was up to, he didn't tell Wilson. We're DVRing the episodes, then watching them in order. Grr. I have several in the queue, but I'm missing one that will show next weekend before we can move on.
