I accidentally made Flume's forehead marking look like another eye and had to debate whether to give him one. At some point i made a note in a very outdated and abandoned google doc that he had three eyes, which I forgot about until recently. I decided it is nonliteral because it looked very odd when I edited the reference. Attenue already has a third eye and it's a rudimentary mark on her forehead so I guess it would be redundant.
