Damien doesn’t like mirrors? he never mentioned the fact to the other members of the family, but they are detectives and vigilantes. It’s their job to be observant which after some years becomes a habit Damien doesn’t actively avoid mirrors.-he has a mirror in his bathroom. He doesn’t express any discovered over going into a mirror labyrinth at some carnival they attended.(the expressed disgusted, overtaking part in something so stupid in his words, but that’s a whole another story) and he actually spend a few minutes in front of the Funhouse mirrors when no one was looking watching his own reflection distort in various ways he also has no problems with his reflection distort in various ways, he also has no problem with self image- he doesn’t mind pictures of himself being taken(unless it’s Tim, but that’s again a whole another story) he draws a few self portraits that were rather accurate and he liked them

he just doesn’t like mirrors for some reason

his family both close and extended, never questioned it. They did some gentle research to see if the dislike was caused by some kind of problem. Damien was experiencing without telling anyone, but when they found no proof of that, they just decided it was some type of quirk of his, everyone has quirks. Duck doesn’t like eating cereal like a normal person Tim despises sleep. Steph is at war with any other colour than purple.

but that is until one day Tim witnesses Damien sitting in front of a mirror.
