The ep covers quite a bit more of what happened 4 years ago - for example, how Fate saved Subaru's sister, Ginga. Hayate helps with organisation a bit until the proper ones turn up (who happens to be Subaru and Ginga's father), then Hayate goes to strutt her stuff. Afterwards, Hayate decides she wants to create her own command to better handle such situations and asks Nanoha and Fate if they want to join. Nanoha laughs and says she'd be angry if Hayate didn't ask them to join such an interesting sounding division.
Fast forward to now, and Hayate and Fate are explaining to Subaru and Teana that Hayate's only just gotten to point of being able to create such a command and asks if they want to join. (As a side-note, Subaru doesn't even know what Lost Logia are. I think we need a "Naze Nani Nanoha" with Reinforce and ferret-mode Yuuno
)
With regards to the exam, though the cleared they objectives, they had too many screw-ups, so didn't pass. However, because they're clearly too skilled for C-rank, they'll be allowed to re-take the exam in a few days.
Later, Subaru and Teana are talking about joining Riot 6, and both seem rather apprehensive - it's rather sudden. Teana seems particularly nervous - that it's too far above her. Subaru teases Teana quite a bit...
The other prospective members are arriving today, though some minor worries about their age / experiance (though not their talent). They're both from other worlds too. Signum arrives late (doesn't really fit her image) but a certain clutzy pink loli hasn't arrived yet either (exactly to image). Elio offers to go search for her, and uses a burst of magic speed to save her when she trips - though kinda screws it up. (Wow, his move was quite cool...)
Meanwhile, Shamal is giving support to Zafira and Vita who are taking out the drones seen in the StrikerS prequel manga. They comment that they're getting more numerous / hard to deal with. Hayate's new unit can't come soon enough.
Next week, Riot 6 officially formed it seems, and... beginning of battle training with Nanoha
PS One brief scene gave me chills. It was Fate asking Nanoha if she was okay (physically). Nanoha says she's totally fine - Fate should know how tough she is. But Fate says she worries since she's a friend. What on earth is Fate worried about? (I bet some jokers will turn it into Nanoha being pregnant or something
) There was a lot of worry in Fate's voice - all that just from Nanoha's little work during the test? Hmm. Is this possibly from a certain major injury suffered a long time ago (as seen in the StrikerS prequel manga?)
