Be it in bad taste to say that Catelyn Stark's narrative in #ASoIaF comes to a screeching halt? Mayhaps you feel it is if you are a big fan of Lady Catelyn. However, if you are a big fan of Lady Catelyn, this is likely not a podcast you will enjoy listening to. That said, has anyone really gone on record saying that Catelyn Stark is their favorite character from A Song of Ice and Fire or Game of Thrones? Not bloody likely.
If there was a House Dumb-Idiot of StupieLand, the matriarch would be Catelyn Stark (or Tully, as it were) and the sigil for House Dumb-Idiot would be a crude depiction of the synapses in Catelyn's brain lighting up as she takes advantage of a situation to further her personal agenda of escaping from the North and stumbling into her own circle of power in the South.
These different and sometime conflicting versions of the same minor character of A Song of Ice and Fire aren't so glaring that they take anything away from the story... However, Renly Baratheon's schizophrenic personalities don't help people such as John and I when we task ourselves to analyze and understand what should be, in all honesty, quite a simple exercise.
