Losing Lucky Strike has left Sterling Cooper Draper Pryce weak and gasping for air in Season 4, Episode 12. But, as research king Geoff Atherton says, the agency still has Don. Don proves himself again as he makes a bold move to change the agency's fortunes. Whether it works will be subject of the season finale.
Early in the episode when the agency appears to be crashing down and Don doesn't know what to do, Peggy reminds him that he always said that if you don't like what people are saying about you, change the conversation. Don, the self-made man, can't just let fate have her way with him. He has to do something.
