I don't remember why it was wrong. He may have been her therapist, or he might have been her client, don't remember exactly what. They slept together a few times on the downlow and Ava found out. He died (don't remember how) and when Ava told his brother he blamed Alexis and demanded she loose her license.
Does anybody remember why it was unethical for them to sleep together ... or how the guy died?
As for Ava, I'm assuming she was getting back at Alexis for turning her back on Julian when his crimes were exposed. I wasn't watching on the time but maybe she blames Alexis for Julian's death.
