I loved this episode. Base invasion of both heroes and villains, staff picking weapons to fighter, Messiah's appearances towards the ending...
Still, they just can't keep this kind of excitement for long, and if you think about it, the entire story has been taken over by small plot elements introduced in the last two episodes, which just screams retool. I mean, this episode itself now revealed the commander and Jin have actually been in contact with people in the Subspace and new they were alive, but hid it from the Go-Busters... It's fun, but I can't see the show going very far like this, and I don't know what they're going to do to replace pretty much every plotline of the show.
I really hope the last 20 episodes aren't just random monster of the week battles against Vaglass remnants.
