[x] Well, she can listen to Carmen if she really wants to, but you want to point out that she's probably not really sane at this point, spending 10 000 years in what was probably very close to sensory deprivation would do that. If anything, you would like to have a talk with Carmen if possible, she is your mother in way after all, and you want to know how she ended up thinking that much like Adam.
[X] She can listen to Carmen, we can't truly stop her from doing so, but she shouldn't. Carmen is bugnuts crazy, and while she may want what she thinks is best for her, she likely doesn't understand what that means for someone anymore.
[X] She shouldn't listen to Carmen.

[X] She can listen to Carmen, we can't truly stop her from doing so, but she shouldn't, Carmen is acting as her impulse, using her for some grand plan and nobody can know, Carmen does not have her best interest in mind, but she thinks she does.
