There is a lot of inbreeding in Westeros. Lets take a look. We will start with the most inbreed.
It all about families, houses and kingdoms. The families of the houses are always very unhappy with being forced to (outbreed) join their houses. It’s a good thing they are forced to do that to stay in power. You will also notice the inbred don’t like their inbred children. Though Cersei loves her daughter (Who is your daddy?)
Daenerys – Molested by her brother then given to a inbred savage. Frees slaves just like she was freed by intentionally killing her owners the Karl and her brother.
Robert – Drunk
Stannis – So inbred can’t make babies just still borns and demons.
Renly – So inbred selected by nature not to bread. Not loyal to brothers.
Tywin’s real legacy – Married his first cousin (Joanna Lannister) His twins are making Joffrey. Tyrion is an imp. He killed the family they where meant to breed with (House Reyne). Then tried to fix his mistake with the Tyrell’s and Starks far too late in the game.
Jaime + Cersei = Joffrey – Most inbreed you can get hence desire to hurt everything. Normal people get joy from love inbreeds get joy from hate.
Tyrion – Only likes whores or whores are as inbred as imps.
Why give the least inbred girl to Tyrion? Trying to most up bread his kin?
Why not give her to Jaime? Maybe make her have a child with both. Margaery should have a baby with Jaime but stay wed to Joffrey. (FYI I’ve not seen past season 3)
Margaery – Inbreed enough to want a 3 way with her brother. Not too inbreed but just enough to control Joffrey.
Loras – So inbred selected by nature not to bread.
The most outbred in the land so the inbreds killed them all.
Ned + Catelyn Tully – Least inbred family
Robb (Traded for a different level of inbreding maybe regreted it)
Sansa – Despite the least inbreeding falls in love with Joffrey and a gay Tyrell. Might just be because she is young.
Ayra – Acts like a boy level inbred.
Same level mix cross inbreeding
Shunned super inbreeds
Lysa Arryn – Wed as child to John Aryn hand of the king who was killed over breeding. Has a child with Petyr Baelish who was a Tully ward that is in love with her sister. She made him master of coin and put him on the council. They would later be offically matched. Jamie “the kingslayer” Lanister was matched with her and that is why Cersei named him to the kings guard.
Craster – Lots of wives. Lots of duaghters. Lots of inbreeding. This guy single handedly grew / feed the white walkers.
Lord Frey – Lots of wives. Lots of duaghters. Lots of inbreeding.
Greyjoy – They live on a tiny island and everyone is scared of them.
Kill the outbreeds
Inbreeds no fucks given
