House, Wilson, Foreman, and Chase are celebrating Vogler's leaving with champagne in House's office. House is sitting on the bookcase by his window, holding a mostly empty glass. Cuddy walks in, and House begins to fill a black coffee cup on his desk. While he is still pouring champagne into the cup, Cuddy suddenly has the glass in her hand, and it's considerably more full than when House had it.
During the final argument between Vogler and Cuddy at the board meeting, the boom mic is reflected in the window behind Vogler.
