However, the pair find Louis rummaging through Harvey's office. Harvey nearly punches Louis before Mike stops him.

Mike crashes the meeting and declares that he has a sworn affidavit stating that Hardman knew about the C.M. defects and wrote the memo himself. Jessica declares that Hardman had engineered the whole suit against her firm, forcing the partners to pay $100,000 each of their own money, for the sole purpose of buying control.
