It isn't until Lucas' murder of John Winston at a local diner does Markus become more involved in his brother's life. The ordeal causes Markus to struggle with his religious beliefs, to choose between his faith or his brother, and in fear of the police possibly killing him, Markus willingly hides and aids his brother as Lucas delves deeper into the conspiracy surrounding the murder.
