I thought we were going to tell them both together as the "powerless advisors" group, instead of having Madoka feel singled out.
Can confirm, I am pretty sure that the original goal of having this conversation was to inform the both of them due to the incident in tokyo.
In fact, didn't we say that we would explain to them? I am not sure this idea of not telling Madoka is a good one, she already knows there is something, telling Hitomi and not her is just asking for trouble down the line.
