"I need to prove what the vice president is capable of," Frank tells Claire, later. "Don't prove it to them, prove it to me," she responds. No wonder he loves her more than sharks love blood.
When Mendoza tells Frank that he can't wrangle Haas, Frank and his staff start working on ways to bend senate procedures, and start arm-wringing some senators that they'll need to vote their way, and others that they'll need to abstain from voting.
The Republicans fightback, instituting a quorum call, which is, essentially, a filibuster technique, one that the senate majority party was willing to ride all the way past Frank's deadline. Frank charges in and breaks that up, but the Republicans counter by staging a walkout.
The Dems respond by proposing a motion that would issue arrest warrants for all of the senators that left the chamber, should they not return. With only three Republican senators left in the chamber, the motion passes, and the rest of the Republicans are brought back to the chamber, forcibly. "It feels good to be back in Congress," Frank smirks.
Mendoza meets privately with Frank and agrees to force enough of his people to return to the chamber to force a vote, but with some theatrics. Mendoza plays it as though he and five of his colleagues were brought back under protest. It's not exactly true, but it provides him a chance to save face, so Frank goes along with it.
Frank has his grand compromise, and his victory.
Tusk calls Frank to congratulate him on his win, and tries to explain that he told Walker that he had faith in Frank. Frank knows that isn't the case, and calls Tusk out for being two-faced. "It's okay, Raymond. Jesus forgives you," Frank tells Tusk.
Lucas meets his Deep Web contact in person. The contact is played by the guy that I'll always remember for playing Lyle the Intern on "The Late Show with David Letterman". After frisking him, the paranoid contact tells Lucas that he contacted him because Lucas was desperate. "And I'm not fond of authority," he adds.
The two watch as President Walker delivers his State of the Union, while Frank applauds in the background of the frame.
