[Gearhead]

Spoiler:

Just an observation.. Nanoha and Fate are going to have very different perspectives on how to properly raise a child. Fate has Alicia's memories of Precia and Lindy's example to fall back on, and both were very kind experiences. Nanoha, on the other hand, grew up in a practicing samurai household where the elder siblings were learning how to handle live steel. It makes sense for Nanoha to be the more stern of the pair.
