You are a scientist who recently worked in the SCP foundation, therefore, for a few months you have been placed in control of a relatively friendly SCP, SCP 073, also known as Cain.

Today, like every day, you go to his cell, and start to browse through various documents, also getting help from him since it is often used as a sort of human archive, and today, you came across the file relating to SCP 076 in your hands, Cain's brother, Abel.
