Daenerys is, like, 14 years old
Daenerys is in a rough spot when Game of Thrones begins she's the exiled daughter of a brutally-deposed king, her psychotic brother has arranged for her to be married to a nomadic warrior king who's really into horses, and just look at how that name is spelled. She probably has to correct people all the time. But the real messed up thing is that she starts off the books at the age of 14. That's when she's forced into having sex with her new Dothraki husband. So remember that cool Khal Drogo guy? He's a child rapist. The show gets away with making this all seem not-creepy-as-hell because Emilia Clarke is in her 20's (she would be a great-grandmother by this point in the world of Game of Thrones).
So whenever you get excited to see Daenerys nude in Game of Thrones, remember that Chris Hansen is going to knock on your door at any moment.
