random oblivion!vilja fact #1
vilja has around 7k lines of dialogue. a lot of them are extremely rare or 'never heard before' voicelines, as either they weren't programmed properly (which is understandable considering vilja has so many lines) or actually getting to hear them in-game just isn't possible due to their trigger conditions being too niche or straight up impossible.
so vilja has this funny little running gag where she REALLY hates m'aiq the liar, because the khajiit who scammed her sister was somehow related to him. curiously, vilja has unique combat dialogue directed specifically at m'aiq, and under some kind of script reference named 'killcat' which, if triggered, probably would make vilja go nuts and chase down m'aiq, with the goal of attacking him. i've never seen this happen personally and i'm not sure if this function is programmed correctly or if it even exists? you can put vilja and m'aiq right next to each other and nothing happens, other than m'aiq having a vilja dialogue topic, and vilja telling you about him and his relative, but nothing causes them to fight.
some of the lines here also seem to get reused for vilja's generic combat dialogue against khajiit NPCs, but she still has a few unique ones for m'aiq exclusively. (those being "I'm gonna chase you all over Cyrodiil!" and "Ha! This time I'll get you, filthy cat!")
the reason we never normally get to hear these is because m'aiq will never try attacking you like any other hostile bandit NPC would, for instance, so attacking him results in assault, something vilja won't partake in. i think the only way you could potentially hear these is by casting a frenzy spell on him, and even then i'm not sure if the lines would trigger at all, and i'm not sure if the 'killcat' script even works. it could also just be a cut feature! m'aiq is also flagged as essential so he can't be killed by normal means, and i guess this feature would just prove too troublesome for players, since attacking non-hostile NPCs would make any nearby guards chase vilja down.
despite the inconveniences it still sounds really funny, since m'aiq runs insanely fast, seeing vilja chase him with an axe across 3 cities would be peak comedy tbh. we all know vilja's winning baddies tamriel ππ
