Episode 10 has several between Jin and Yunoha. Jin is interested because he recognized the power that first defeated him, and Yunoha feels a connection with Jin because he seemed like her when she started school.
Episode 12 has few good moments for Amata and Mikono, as well as some Jin and Yunoha moments.
Amata opens up about his Mom to Mikono while Mikono tells him about her brother leaving her. This really shows the improvement in their relationship since episode 1 where they were clearly trying to avoid such topics.
While watching the movie together, they hold hands and due to his excitement Amata starts flying and he begins to carry her, Bridal style, while they both gaze into each others eyes.
Episode 13 where Donar shields Suomi from one of Mykage's attacks. Also, literally every scene between Jin and Yunoha after his official Heel Face Turn.
Even before that, I found Mikono and Yunoha's Friendship Moment rather touching as Mikono comforts Yunoha during her Heroic BSOD, and persuades her into finally going to Jin's funeral.A Friend in Need, indeed...
There are a few in episode 26, even Touma gets a moment, but Amata and Mikono's stands out. Also, this is probably the only time the phrase "I'll love you to Infinity!" has been as epic sounding.
Finally, after 12,000 years since Solar Aquarion saved the world, and 24,000 years after Pollon fell in love with Celiane, Apollo and Silvia can finally be together.
