Do you think he meant do you want to work together? You know, see each other again? A first session is kind of a trial, so maybe he wanted to know if you wanted to continue with him. I think when we first meet someone, not just a new T, we don't know their communication patterns and styles and it is easy to not get what they are saying. With familiarity that all changes (hopefully). If he was OK besides this one question, is that enough for you to want to see him again?
