Someone here said something about reverse engineering, which wouldn't be a surprise, I suppose. The VF-27 seems to be far more advanced than the -25. While we're not 100% on the NUNS markings on the VF-27 (well, I am ), Brera does have Zentradi ears, and he carries a harmonica (I like the Harmonica nickname, BTW, very Sergio Leone), so think one can safely assume there is some UN connection there.
