Reference to the 'Tattoo' and 'Not liking him because he was an alchemist'

Alchemy Circle Theory[]

There has been a thought that this may suggest something in relation to Fullmetal Alchemist.

I was thinking what if this is a reference to Fullmetal Alchemist? He seems to know anime and videogames, In FMA Homunculus have these ‘tattoos’ and the story is about the building of a giant alchemist circle to sacrifices a whole nation of people to make a philosopher's stone. He also has a video on Homunculus and alchemy and talk about metals and such....

Yeah could be trying to draw triangles like this. (In reference See pics)
