What's begun as friendly banter I think may be turning into more, although Henry is so aware of his father's not-so-subtle hinting and maneuvering that perhaps he's just trying to keep his dad off his back.

On the other hand, there is that line I mentioned in a previous thread that hints otherwise: "Catherine, meanwhile, undisturbed by presentiments of such an evil, or of any evil at all, except that of having but a short set to dance down, enjoyed her usual happiness with Henry Tilney, listening with sparkling eyes to everything he said; and, in finding him irresistible, becoming so herself." Perhaps Henry is finding himself attracted in spite of himself. :-)
