I missed most of the meat of the episode, especially the parts concerning Hayate, due to lag ;-;
The important part though at the end though:
Spoiler:
Freyja for some reason doesn't seem to have passed the Walkure audition at the Macross Elysion, so she's riding a monorail back.... just as the entire car's windows blacken, and there's a Var Syndrome alert coming in. One of the men in the car suddenly attack and kill a woman with blood spattering everywhere, and he's shown to be infected by Var.
Naturally, Freyja is knocked down and she almost whimpers in fear as the Var-infected man stands over her, until she remembers the reason she wants to join Walkure and then sings to the infected man to cure him of his disease.
... or so it looks at first.
Turns out that the other passengers in the car were Mikumo and the rest of Walkure in disguise, and the Var-infected man and his "victim" were also actors playing along. And due to her bravery under fire, Freyja is given her holo-costume on the spot, and welcomed as Walkure's newest member.
Also, from the bits I saw of the episode's first half, I like how Delta, as with Frontier before it, once again shows us lots of world-building tidbits that make Ragna really feel alive, including showing Ragnarians as being amphibious.
Missed the OP unfortunately, though what I heard of the ED was really nice and catchy.
