Well, things are getting dramatic as we build to the finish. Kengo's mother comes back into the story, all the secrets come out, Yuna almost makes the big sacrifice, Ignis decides where he stands. And we still know practically nothing about the three supporting GUTS team members.
The scene of Kengo and Ignis transforming together reminded me of Kamen Rider joint-henshin scenes. I was almost expecting another KR-style trope -- having Yuna transform into an Ultra herself for the climax -- but they didn't go there.
I still wonder if Shizuma was meant to be a returning Tiga cast member, but became a new character when they couldn't get one. It's surprising how little connection to Tiga's universe this show ended up having. But maybe there will be another connection in the finale.
Isn't it weird how the Color Timer starts blinking red when the Ultra is almost out of time, but then just keeps on blinking for as long as the battle scene needs it to, even if it's longer than the amount of time it was solid blue? It's made especially weird when Trigger is able to activate Glitter mode after the Color Timer warns that he's almost out of energy. If you're going to use a ticking clock to build suspense, at least have it actually mean something.
