Oh shit, the latest episode of AnoHana, Menma finally proved she was real. There's still one question that needs answering: what did Menma call them over for? I'm speculating that her wish is for them to remember the name of the flower they saw, which is the name of the flowers appearing in the series through the OP and through color symbolism, 'forget-me-not'. If we're going of the myths associated with that then Menma dies by slipping by the river bank, and her wish is for them to remember her while moving on in life. Something like that. I'm interested to see how they'll grant her wish though, or how they'll find out about this. The next few episodes are probably going to go into full nostalgia mode.
