Rumi Question (spoilers)

Of course it's Rumi. And of course the audience saw her as a fat woman. They just thought that Mima gained a lot of weight between gigs.

It could be Rumis imagination, the glow around her is there for a reason.

Well you hear these guys talking about the concert, and they say Mimi is performing tonight. Because that was on the website, and the other two girls seem to look at something. So i personally believe it was Rumi on stage.

Yes, I believe Mima was just influenced by what she read on the website; the website claimed Mima was going to preform that day, so she thought she did. It was all in Mima's head, I think - she was using the website as a "guideline" for her own life.

i figured that the creepy guy was imagining it.

I actually thought it was all a part of Me-Mania's imagination, too. He wanted her to be on the stage so badly that he projected his vision of her on the stage.

Although I am a bit confused. The other CHAM girls seem to have been looking at something in between them. The audience also reacted. But maybe these things were also apart of Me-Mania's imagination? :S

I just thought that if Rumi was to prance about on stage, then perhaps it would've been mentioned later on in the film. I thought she'd kept her Mima/Rumi persona to herself. If she'd appeared in public, it would make sense for the characters to talk about it, or for people to have some sort of reaction... Unless that was deliberately omitted to confuse the viewers. :S

I'm another who got the initial impression that scene was Me-Mania's hallucination.

However, upon giving this further thought, I've now changed my mind and consider that scene to be a delusion held by both Mima and Rumi. Literally just before that scene takes place, you see a previous scene where Mima's vision of "virtual Mima" tells her she's about to go off to the concert and sing alongside the other 2 members of CHAM. So it makes logical sense that she is imagining that concert scene. Yet just afterwards, it also says on the "Mima's Room" website Mima was there singing. Given the later events which occur in the film, we come to realise this must have been written by Rumi. And given that she wants to be Mima so much, it would make sense that she deluded herself into believing that she had been there as Mima, and as a result wrote about it on the website for all of Mima's fans to see. But you never see or hear any of those fans actually admit to having watched her perform, so I don't believe that the concert scene was intended to show events as they were really happening, but to portray imaginary one's.

Of course, different people will interpret that concert scene differently. But to me it's the one that makes the most sense from a logical point of view.
