Arata And Suedou, The Lost Joins The Dark

Scar and Arata battle an Humanoid Eater, and guess who shows up after the battle, Suedou! Suedou gives a long complicated speech about Humans, Eaters, evolution, and blah blah. A bunch of this and that, and like a newborn baby Uchiha the fascinated Arata decides to team up with Suedou. Further falling into the depths of darkness and corruption, abandoning Scar and hurting her feelings.

I won't bore you guys with a long detailed breakdown with what Suedou discussed between Arata and Scar. Basically, he wants Eaters to run wild and devour everything possible. Eater evolve by eating, the more they eat the more they can evolve. Suedou wants to witness the outcome of this phenomenon, he wants to see what kind of power these gluttonous programs can ascend to if they continue to feed. More or less anyway.
