Lagrange: The Flower of Rin-ne/YMMV

Alternate Character Interpretation: Villagio is subjected to this in the moment mentioned below. Bit of wishful thinking but he may have delivered the speech because he didn't want Muginami to act without setting her priorities straight first. After all, if he is so evil why not use the dupe for one's own schemes instead of alienating her like that? No skin off his shoulder. Or using his Ovid for killing off the Vox pilots in the same scene, who are oh-so-conveniently away from any support and unarmed and right in front of him.
Expy: Fighter-mode Vox's design is very close to the FFR-41 Mave from Yukikaze. It's reinforced by the takeoff in Episode 1, which is almost identical to the Mave's first takeoff in Operation 2.
Grey and Grey Morality: Everyone's motives are very vague at best- the only thing we can be sure of is that Madoka wants to protect Kamogawa, and everybody else isn't making it clear why they're fighting. The villains are actively trying to avoid causing collateral damage to the Earth and in general aren't that bad of people, they simply want their weapons back when it's not really told why they're on Earth in the first place.
Les Yay: More than a little. By Word of God, there was going to be far more--to the point where Lan and Madoka knew each other before the start of the series, and were implied to be lovers. This was dropped before production.
Memetic Mutation: Not surprisingly, both "Maru!" and "Wan!" appear to move in this direction. More surprisingly, there is also "Muginami desu!", despite the phrase appearing only in one episode.
Shippers on Deck: The girls who produce the student film "The Spaceship and the Lily" (starring Madoka and Lan) are implied to be a bunch of Madoka/Lan shippers.
Tear Jerker: Madoka stopping midway through a "Maru!" and breaking down into tears over Lan and Mugi leaving Earth.
