These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Rinne No Lagrange
Alternate Character Interpretation: Villagiulio 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.
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.
With all the kisses (and a headbutt) in episode 14, they might be working to reverse that decision.
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.
Moe: Madoka, for certain by account of her Badass Adorable status. Lan also counts as this.
The Woobie: Lan is often on the receiving end of various punishments, embarassing situations and her own insecurities. Add an obvious (despite the seemingly stoic behavior) emotional fragility and she becomes this trope. So very much.
Madoka was this at the end of Season 1 especially in the final episode.
