This week Hayate officially learns (in a noxious cloud of technobabble) that he possesses fold receptors just like Freyja and the other members of Walkure. Specifically, he “resonates” with Freyja; something that causes Freyja to blush when she hears about it. Poor girl doesn’t realize she’s in a love triangle the show probably isn’t that concerned with resolving, like the one in Frontier.
Also this week, Messer puts his own pride and personal desire to “repay” his savior Kaname (the one who first saved him from the Var) above his safety and the safety of Delta Platoon and Walkure.
Hayate and Mirage follow the chain of command and honor their colleagues wishes, but insofar as their overarching duty, it seems like a very bad idea to put a ticking time bomb like Messer in a Valkyrie and hope for the best.
For their part, Hayate and Mirage are conflicted over how to do with what they know about Messer, and try to put their heads together to come up with a solution throughout the episode.
Of course, because they’re largely doing this alone, in front of a romantic sunset, everyone, including Freyja, thinks these two are going out now, or something. Freyja is overcome by a combination of jealousy and FOMO, but is too timid to interfere, so she doesn’t, and thus never finds out the truth until the end of the episode, after much emotional stress.
She didn’t happen to stalk Mirage while she was talking with Kaname, for instance, about how Kaname used to be the lead vocalist of Walkure before Mikumo joined, and before that, she was a solo idol.
Kaname is very harsh and frank in her assessment of herself, and flat out believes she doesn’t have the talent to be lead vocalist, and has to be content with leading them in every other way. But as far as Messer is concerned, hers is the only voice that can save him.
That’s pretty strongly demonstrated when the Aerial Knights arrive to do some scans on Ragna’s Protoculture ruins. The camera focuses on Kaname both singing and talking Messer through his Var flare-up as he duels with the White Knight, Keith. Meanwhile, Hayate and Mirage protect Walkure from Bogue’s bold but ultimately fruitless attack.
The Knights retreat almost as soon as they arrive, but not before learning they can use Ragna’s ruins, and Keith is impressed enough with Messer to want another rematch in the near future.
But let’s be honest here: Delta Platoon dodged a bullet here. Had their ace Messer gone fully berserk, he would have fallen under enemy control, and as we saw in training, it wouldn’t take long for him to waste the rest of the platoon.
That being said, Freyja’s misunderstanding is cleared up, though she’s already shown her hand, Hayate-wise, and has to bug out to scream at the night to relieve the embarrassment, in the same place where Messer is alone, thanking his own personal god things didn’t get too out of hand due to his own selfishness.
