Nemuro Memorial Hall: Non aging symbolism

Ok, so i just got to this episode, but I've read a ton of spoilers, so he's what I make of things.

When Tokiko comes back to the school and notes that Akio and Souji have not aged and Akio says that children (he compare gardens to school) can't grow up if they stay in schools, I think that's symbolism for adults who are stuck in the past. Akio and Souji are really her age, but they haven't let themselves emotionally grow up, while she has, but also remembers it, like when she visits Mamiya's grave, and she can live a fulfilled adult life.

There's a lot of represented ideas in this show, like maybe Dios is the older brother who wasn't able to protect his little sister Anthy (because he's sick or he got traumatized from what Akio does to Anthy and is sort of detached from things. We see him come out to help Utena, because it represents that he helped her once so she's paying it forward by protecting his sister and ultimately falling in love with her) from their evil brother Akio, so he appears slightly younger than Akio, because that's how old he was when he discovered what Akio was doing. Akio came from Dios in the show, but that could be symbolic of him really being the next kid who was born in their family.

Also, maybe all the kids represent adults stuck in the past and who still see themselves at the age they're focused on or who are replaying their childhood's in their heads to try and figure it all out, but the show is also symbolic of problems that 10 year olds to 20 somethings could go through (like Mitsuru pulling the sword out of Nanami seeming like sexual harassment and something he sees as making him an adult, because it represents having sex. It's the same way for some of the other characters in the Black Rose Arc, like when Miki's sister pulled a sword out of him).

This is what makes fantasy so great. You can have so much going on at once.
