A little anatomy and my own headcanon Kurtis' tattoos practice <3
There has always been this thought in my head about the tattoos. Let me generally introduce it to You.
Since his father and the LV adepts tattooed him with LV-related imagery against his will, it would most definitely feel like his bodily autonomy has been taken without consent. Like Your skin is not really Your own anymore.
Thus, I am very inclined to think he would tattoo his own body when he gets older, with things that are meaningful TO HIM. Things that HE CHOSE. Not only as an act of rebellion against his father and LV's beliefs, starting a kind of battle happening on the field of his own skin - but also mainly because it would feel like taking his own freedom and body back.
Special thanks to @pixiebluefr for supporting the idea and helping me overcome the fear of sharing it out with You all <3
