From Don to Joan to Roger - 'Mad Men' Season 6 Primer
Where were Christina Hendricks, Jon Hamm and others when season 5 ended?
Betty Francis (January Jones)
In part because January Jones was pregnant, in part because Matt Weiner seems to enjoy putting his actresses in fat suits and other prosthetics, what little we see of Betty in season 5 is that she is much bigger than before, having turned to food to cope with the unhappiness her second marriage hasn't miraculously cured. Betty also continues to use Sally as a pawn in her cold war with Don, but is pleased when her daughter turns to her for guidance after experiencing her first period.
