PLOT SUMMARY: In the pre-credits sequence, President Frank Underwood (Kevin Spacey) blackmails Congressman Romero to drop the congressional investigation.
In private, Vice President Claire Underwood (Robin Wright) is angry with Frank for not sharing his gameplan. He tells her that his resignation was not a last minute decision but part of a long-run plan since Elysian Fields. He has realised that the real power is not in the White House but in the powerful forces who control it. Therefore the most powerful combination is for Frank to control the private sector influence on the WH and for Claire to be running it. She resents him telling her that he made her the President and tells her she has to pardon him for all his crimes once she's President. She says she could be impeached for it. Frank also reveals that he was the leak all along via his Chief of Staff Doug Stamper (Michael Kelly). She tells him to shut down the surveillance and that she killed her ex-lover Tom Yates. He tells her he'll do that as soon as she pardons him and that she'll have to pardon Doug too at a later date.
Claire then tells Special Adviser Mark Usher (Campbell Scott) about the death of Tom Yates in his house.
