Rewatching the TWW trailer again for the millionth time and I think its really interesting how Anduin is like got a botched hair cut and dirty scarred skin and chapped lips and has been wearing the same armor for seven years thats caked in sand and his mental health has crumbled to dust BUT his teeth are still utterly perfect.
which begs the question, was this an oversight, or does Anduin have this ocd-like obsession with keeping his teeth clean, in which he needs to brush his teeth or else something worse will happen? A leftover from being rasied in a setting in which appearances are everything, and having let go of his appearance he needs to do sooomething to ease that internal shame? Maybe the simple repetitive action of maintaining his teeth daily is something that grounds him to life, reminds him he exists, and eases the dissociation episodes.
