This was an interesting one. Mami was portrayed as being pretty jealous of Madoka and Moemura in the PSP game, so it's not like the first portion of this comes without precedent, but I'm not quite sure how that translates to her anxiety about Coolmura in the present-day timeline, which seemed pretty purely about the professional aspects of being a Magical Girl. Unless it's maybe implying a situation of some residual subconscious impressions carrying over from previous loops?
