@Miller,
Quote: What disease does Robin have and why does she want to vanish?
The only thing I know she has is HIV, which she got years back when she was with Stone. Stone had already tested and knew, he lied to Robin, they had sex and that was essentially that. Some time later, he told her the truth but it was too late by then. Her story line also reminded people to get tested a second time, her first test was negative, second was a positive. That was back in the mid to late 90s from what I remember.
No idea why she wants to vanish, I barely viewed the show back then,, haven't seen it in years.
