Why Marry? Because Dany is confident, beautiful, ambitious, and, arguably, the rightful Queen of the Seven Kingdoms. How awesome would it be to stand by her side as she reclaims the throne? Also, she has dragons.
Why F***? Because she has become well-versed in the language of the bedroom through her marriage to Khal Drogo and thorough instruction from Doreah. She's also stunningly attractive.
Why Kill? Because as her confidence has grown, so has her determination to get what she wants at any cost. Dany has left many dead or damaged in her wake, and if she sees you as an obstacle to reaching the Iron Throne, you're likely to become one of them. Did I mention she has dragons?!
Why Marry? Because who wouldn't want to married to the most beautiful woman in Westeros? Margaery is also kind, smart, and more clever than she appears.
Why F***? Because taking the maidenhood of the most beautiful woman in Westeros is the next best thing to marrying her.
Why Kill? Because the Tyrells have thorns hidden behind those rosy exteriors, and they are less pliable and predictable than they originally appear.
Why Marry? Because she's spontaneous, fun to be around, and good-humored. If you want a strong, confident wildling woman, Ygritte's your gal!
Why F***? Because her passion is as fiery as her hair. She's experienced and insatiable, and has probably picked up some tricks during her adventures beyond the Wall.
Why Kill? Because she's an unpredictable wildling and killing is in her blood.
