Teana's fight was great because it wasn't very impressive from a typically Nanoha climax fight. What made it great is that she thought about what she would do. She noticed the three attack in the same way often, and took complete advantage of them. Her peashooter isn't flashy, but her bullets pack a wallop. Nanoha trained her to make penetrating bullets after all.

A perfect contrast to Subaru's fight. Use twice as many cartridges, and break out a Subaru Divine Buster that more resembles Starlight Breaker (The little tracer beam first, then the full blast). It seems to me like Ginga didn't have an IS. My guess is she was the original prototype, Subaru was the improvement. Looks like they are also clones of their late mother. Hmm...who else was in Zest's squad photo? Quint (Ginga and Subaru's mother) and Lutecia's mother.

Vivio should be too hard for Nanoha to make friends with again. Her adult hairstyle is Nanoha's, and her barrier jacket resembles Nanoha's as well. (With a bit of Ginga/Subaru thrown in, strangely enough). She still knows who her real Mama is, at least deep down.
