Jon Hamm has predicted that after the end of "Mad Men," Don Draper, will return to his old life and habits, which he believes led to the death of his ex-wife Betty. Hamm mentioned his character's journey to a spiritual retreat in Big Sur, California, where he discovered the inspiration for his greatest advertising campaign: Coca-Cola's "I’d Like to Buy the World a Coke." He also mentioned one of his favorite scenes in the seven-season series, where Don and his co-costars Roger Sterling had their last scene together.
