"Core #2!"
The Enneagram Avatar who represents sinner of #2 named Joshua has stepped up. The Enneagramer named Joshua declares that he is afraid of Lizmarie's rejection again. He wants her to fall in love with him. He can't move on nor does he want to.
Joshua states that he will become a walking social experiment. He is always recording anything and everything he finds interesting. He also does it in a sense that he makes himself an experiment bodily wise too.
Xavier once asked "isn't Lizmarie your best friend?" Joshua answers with "Lizmarie is my favorite person, that itself is different from a best friend. Besides it's not like Lizmarie would consider me her favorite person or anything back anyways. I can't call her my best friend and for her to not return it back. That's my personal values to avoid being harmed anyways."
Enneagramer #2 Joshua has erased 87% of the world just so Lizmarie can be at peace. Joshua claims that he will be 'Eren' just so his 'Mikasa' can be at peace. Joshua with his avatar proceeds to disintegrate into heaven.
