So it’s worth noting that I left it entirely ambiguous, in Dr. Anton’s dialog, that she was in fact subject to normal ethical/legal standards for confidentiality. (Within the trope that people will, rather than lie, simply speak misleadingly.)
It is possible that Alex is able to get access to Dr. Anton’s notes. In completely legit circumstances, they are in her personal Box folder, to whom nobody but sys admins have access. (Heck, they might even be encrypted files within that, but, hey, Alex.)
It is also possible that Alex finds the file data within Hellbinder’s private student files. Whether that is because Dr. Anton is feeding him the information, or because he simply has that level of access are both intriguing possibilities.
For that matter, Alex might find that Dr. Anton is an AEGIS plant, and copies her patients’ data into encrypted AEGIS databases.
Any of the above would also, with Alex’ guile, expose a variety of other students’ files to their access. Which raises the question of whom else Dr Anton, regardless of her actual status and motivation, is counseling.
In short, I am fine with Alex having access to Joe’s files. Where Alex finds those files, I’m also happy to leave to you, since all have different and interesting plot points to them.
