What a sticky situation. I'm so sorry this encounter occurred! Anyway, your therapist cannot talk about you to your former friend unless your friend brings up the incident. And if she does bring up the encounter with your T, then he still can't say anything about you. He can listen to her, as he can listen to you. He can ask questions, he can help to reach insight However, he absolutely and positively cannot talk "about" you. It would be a complete break on the code of ethics, and he could potentially get in a whole lot of trouble. Again, it sucks that this type of situation had to occur. But please try to share your feelings with T. Or at least share more of your worries with him, about how you don't want to share anything that might make him judge this person. Yuck. It really is sticky.
