Ben confronts Charles Widmore in his penthouse and there is a heated exchange. Widmore is now keeping a bottle of MacCutcheon scotch whiskey next to his bed since "the nightmares started." We first saw MacCutcheon in "Flashes Before Your Eyes," both in Widmore's office as well as on the island when Charlie, Desmond and Hurley are singing and drinking around the fire.
In the last screen, you can see the painting of the Black Rock that Widmore won in an auction in "The Constant" [see this post]. It's on the wall in the top left corner.
Ben informs Widmore of his plan to kill Penny as revenge for Alex's death in the scene. Will Sayid be told to kill Penny? Why does Widmore say that Ben took all he has from him? This scene poses a million questions.
