#just add like another slightly gore layer... possible bleeding during things like the appearing of arrows or when mari starts glitching

[gummigvts]

This could go for either Mari or the Narrator but imagine dark room and markings just start glowing on them; lines of code in mari's case and arrows for the Narrator. Either its completely hidden when it's light or they are instead like white faint scarring on their body, almost invisible until certain lighting.
