In regards to Lonney, it seems to me that Lonney may have established a good therapeutic relationship with this previous client and that may be the reason that he feels uncertain about how to respond to the friend request.
I would address this observation with Lonney, with the goal of Lonney being able to notice the effect the client is having or may have on him. Furthermore, I would also suggest that Lonney review standard 1.2 dual relationship definition, 1.2.1 unethical dual relationships, 1.6 exploitation, and 3.7 therapist values, of the CAMFT code of ethics.
