From Don to Joan to Roger - 'Mad Men' Season 6 Primer
Where were Christina Hendricks, Jon Hamm and others when season 5 ended?
Ken Cosgrove (Aaron Staton)
Ken continues to be the one man at SCDP with the ability to separate his identity at work from the one he has outside it, refusing to help the agency land his father-in-law as a client and selling science fiction stories to magazines under the name Ben Hargrove. When failed memoirist Roger gets wind of Ken's ongoing literary success, he orders him to stop — which just drives Ken (who was tired of sci-fi, anyway) to adopt the new pen name Dave Algonquin and work on more down-to-earth fiction.
