After the extermination that killed Adam, Crimson was in his office in Greed trying to come up with a new plan to destroy (or kill) Glitch. That’s when his eyes caught onto a news report about the extermination and he saw not just the exorcists, but he also saw Lute.

Crimson: Perfect…

He grins evilly as he had a new plan. He calls up the Sin of Greed

Crimson: Hey Sin of shit….I have an idea…

Mammon on the phone: What’s that mate?
