Like Minutoh, I really never truly bought the nagisaXmami paring that rebellion brought us. Sure I was happy to see that mami can no longer be stuck to the fifth wheel role all the time, but it still bothered me since there was no background between them and yet they looked closer to each other than the series' main pairing madohomu.
I think the only reason nagisa was put in rebellion was either she was the 2nd witch next to walpugris that fans will most likely remember or because people were already pairing mami with charlotte even before the movie.
I'd like to think the latter is true since the movie was like the ultimate service to the show's yuri fans since they put elements like:
1. Kyoko and Sayaka living together (not to mention that tear jerking confession at the final fight, lol)
2. Homura confirming that her feelings for Madoka were love, not just the extreme friendship that most magical girls show exhibit (although some people will argue that the "love" homura supposedly felt was some kind of other psychotic feeling. as for me, imprisoning the girl you love in a new reality is kinda standard. lol)
3. The movie ending with the characters being paired up. I mean come on, that's just like the creators telling everyone that those pairings are now official canon. :))
Anyway, great read. I always get teary-eyed whenever reading PMMM pieces like this since the series was actually my introduction to the yuri genre.
