Who convinces the boss to lay off the man who's favorite mug is missing?  Answer the above question based on the context below:  Derek Cho, the film's protagonist, tells the audience about the ID-7 virus, or "Red Eye" virus, that has been spreading throughout the world. It infects neural pathways, removing all inhibition and moral integrity, and in turn, causing people to act out their darkest impulses. While the virus is not lethal, those infected by the virus may find themselves driven to kill. The first known case of murder driven by ID-7 was committed by Nevil Reed, who stabbed a coworker, but was not deemed liable due to the influence of the virus. Derek, a lawyer at Towers and Smythe Consulting, works for the firm that handled Reed's case; he began his job full of optimism, but ended up back-stabbing, cheating, and finding loophole after loophole in order to work his way up the corporate ladder and get a corner office. One morning, Derek goes into work to find that his favorite mug is missing, and meets with a furious client - Melanie Cross - who needs more time on a loan, but thinks he's unable to help her. After discovering that a bungled legal case for massive company Vandacorp has been pinned on him by his superior Cara (called "The Siren", as she always has the boss's ear), Derek confronts her and finds that she has taken his mug. They go up to their boss John Towers' office to plead their cases, but Cara wins the boss over and has Derek laid off. Derek's friend Ewan is unable to help him, and he is given official notice of his firing by his coworker "The Reaper". Derek takes his things and is escorted downstairs by company security, dejected and afraid of being disbarred.
