Talk:Episode 22 - Longing for the Road of Continuation/@comment-5885873-20160912191158

My theory on the episode and tragedy:

Hime and Yume have this mysterious power that for now I will call Prism Voice, because it helps them sing. Yume and past Hime can't control that power yet, they're just getting to know it in first year (and hopefully will manage to control it later) and when they're emotionally high, they use Prism Voice which helps them but comes at cost: it affects their normal singing. They used too much power and they need to "recharge" it. Past Hime has used this power much more so it not only took her voice, but her strength too as seen in flashback. Present Hime recognises Yume as having Prism Voice too and tries to take care of her to prevent Yume experiencing same things as her.

Hikaru also knows this and experienced this with Hime, so he tries to either raise her banter high or to fail her so she won't experience the tragedy. I'm sure the picture girl and Lily have something to do with this too...
