BlueKraid and Davidddizor are Guilty.

[We see BlueKraid and Daviddizor in the living room]

BlueKraid: "Daviddizor, how dare you cancel sisters marrying brothers! That was innapropriate! That does it! I will kill you!"

Daviddizor: "Please, no, BlueKraid! Do not kill me!"

BlueKraid: "It does not matter, Daviddizor. Now deal with it!"

[BlueKraid kills Daviddizor]

BlueKraid: "Yes! I killed Daviddizor!"

[Cochrane-A shows up]

Cochrane-A: "BlueKraid, thank you for killing Daviddizor. I know that we hate him. You are ungrounded. Now you can do sisters marrying brothers if you want."

BlueKraid: "Thank you Cochrane-A."
