All we needed was the slightest look from Reina to know, with relative confidence what was amiss and why: Thanks to Hashimoto, Reina learns that Kumiko knew about Taki’s wife before she did, and she’s angry Kumiko never told her.
Whether Kumiko was busy with Asuka and the other girls, and was going to eventually tell Reina, we’ll never know. But we do know that Kumiko hesitated as long as she did because she didn’t want to hurt Reina.
During Reina’s suitably elaborate procedure for confronting Kumiko – by going to the summit of the mountain that seems to accentuate Reina’s beauty – Reina yells at the top of her lungs, asks Kumiko why, and gets the answer she already knew.
Reina turns out not to be that mad at Kumiko after all, but at herself: at the weakness she exhibits upon hearing this news; the fact she didn’t know. Her armor has cracked just as the Nationals approach, and while she can say she’s going to “forget about it” until they’re over, it’s likely she’s not 100% sure she can follow through.
Kumiko, for her part, tells her she’s still rooting for her, making sure Reina hears that Taki isn’t married anymore, even if it’s hard both to say and hear. She’s almost making up for not telling her to begin with.
It’s another wonderful scene between the two friends, and a very welcome one after Reina’s presence had dwindled in recent eps. Both the animation and the voice performances soar.
In a quick flashback, we see a young Reina first lay eyes on Taki and fall for him right then and there. She quickly finds how hard it is to follow through, having an elaborate, warm daydream in which Taki compliments her playing and gives her a piece just for her to play.
She’s ripped from her reverie by the real Taki-sensei calling her playing “weak.” She needs to get it together. But how?
Reina finds a way. While delivering the practice room key back to Taki at the end of the day with Kumiko, Reina asks him about his wife. Not about where she went to school or who she knew, but what she was like.
Taki opens up to her, and confirms what Reina had suspected, but wasn’t ready to face until now, when her playing is being effected by the doubt. There is not doubt; Taki still loves his wife, and he very likely became their director for his wife’s sake. He wants to go to the Nationals and win Gold for her sake.
And so, we see both Reina and Taki at their most vulnerable and emotional this week. I guess Christmas came early!
Having gotten all the answers and confirmations she needed for the time being, Reina returns to normal, and starts playing the way she and everyone else have come to expect. Niiyama gives her the location of Taki’s wife’s grave, where takes Kumiko and prays.
That flashback was the beginning of Reina wishing time would move faster for her, so she could catch up to Taki. But now she has another goal to set her sights on, something that she wouldn’t have been able to accomplish if she was his age: She’s going to help Taki win Gold.
