This episode is one big TOLD YOU SO. Keith taking down Roid was foreshadowed
for ages. The question was would he die himself to do it or would he survive? Could have gone either way (Keith himself was a big death seeker character). I felt their relationship and scene was actually well done. It was one of the few things that had been gradually developing and wasn't a dropped plot point.
Bogue being the hero was hilarious. He returned to be that good kid who used to idolized Keith by letting go of his hatred. He was more proficient in saving Walkure than killing them.
Well, even if I didn't like Freyja/Hayate, I'm glad they didn't cop out her healing like Sheryl's. Yet anyway...
