HWA, it's a good opportunity to remind them you're not the crazy, evil wierdo your W has probably described to them. Just be calm and confident, chat without getting into anything deep.
I've been in sitches where person 1 told me crazy stuff about person 2, then when I saw person 2 again and they acted normal and sane it left me thinking that perhaps person 1 was the one that was really off the reservation. So strive for that. Leave them with a good impression.
