- Teana wakes up in Shamal's medical room,
pants-less 
Just as many people guessed, Nanoha used Magic-Damage setting and her's was so well-skilled that left no harm to Teana.
- Enemy alert when they're mentally sensitive... old but it still makes drama nonetheless
- Spagetti releases drones for "performance test" and expect them to be shot down, and it seems that these Type-2 were much more fast and agile compared to these enountered in Ep5.
- Hayate wonders whether they should one-shot these bug with big-gun, but Aces decides that they should stick with their conventional method, so that Spagetti won't get much more info from them.
- As rookies can't fly, they're ordered to stay back in RF6 base and Nanoha ordered Teana to stay out of this mission...
- Teana got PWNED once again, this time by Signum
Surely, however, she deserves that though... asking stupidly clear question when they're on duty, and just about to launch for scrumble situation.
T: "WHY? Is it because you do not need someone that does not follow the order!?"
N: "You already know the answer by saying that yourself."
- Finally the revealation of the... "incident".
It's explained that repeated use of high-power-output artillery-magics (especially SLB) which is
very stressful to her body, then shortly after she dared to use then-unstable cartridge system and Excelion Mode, which boosts ability of user
beyond one's body can withstand...
All these stress were building up on her body, and after 2 years when she was suprise-attacked by "Unknown" when she was on her way back from mission, that stress caused her reaction delayed for a fraction of time... and that costed her that injury.
(In other words, we still don't know what that "Unknown" was, yet.)
It was so severe that she was even told "she may not be able to stand and walk again, let alone flying".
She eventually recovered, but she does not want other to go through such a mess... unfortunately though, her intention did not reach Teana.
- Signum "Surely, there're battles that you must pull out more than you can do, but the previous mission was it?"
Of course not, nor the mock-battle in question.
- Cross Mirage's "Mode 2" is shown to be a kind of round-dagger...
Nanoha, too, knew that Teana will need it some day... since she wants to become Enforcer and Enforcer is basically stand-alone in duty.
What Teana failed is that she was still far from mastering her "most basic" fighting style, yet she recklessly went for even more trick.
Once she achieved certain success in her sharpshooting, Nanoha wouldn't have denied her learning CQC too...
Nanoha also reminded Teana that when used correctly, Cross Fire can be really effective... (She used it against Tia in Ep8)
That implys that there're much more room for her to make improvement in her "basic skill".
- Literally, exactly what Riker posted did occur... to Nanoha.
That "I'm sorry, I'm sorry..." made me certain that Nanoha added one more girl to her harem (j/k
)
