The first demand, after proper relaying through Leon, has a not very satisfactory answer. Answers. The first answer given is that a 'fix' would be to just modify an off the shelf p-fix or some of the closer non-persona fix BTLs to not self-erase and then run it on her until the persona takes, with all the worries and possible side effects that can have. That doesn't really get a good response, for obvious reasons, so a reluctant second answer would be to try and find some kind of psychiatric facility that is both trustworthy and specializes in persona fix and better than life addiction or is otherwise able to treat those addictions in what would normally be terminal stages. Those are the only reliable answers they can think of.<br/><br/>The cleaning has a ridiculously mundane answer. They needed to clear the hazing in the work area and could only work (both the cleaning ritual and the actual experiment ritual) inside. Thus the sphere of influence that was cleaned was strictly limited based on that need and restriction.
