When Roger Sterling (John Slattery) was married to Mona (Talia Balsam, John's real-life spouse), he carried on a long affair with Joan Holloway (Chrisina Hendricks). He wound up divorcing Mona, however, to marry the very young Jane Siegel (Peyton List). The divorce cost him a fortune. Yet, he got back with Joan, for a "quicky" in a semi-public place after they were both mugged. Joan got pregnant... He seems to really love Joan and cheated on Jane in having the quicky.

Is it just that Roger only wants what's just beyond arms' length?
