True. I was going to comment on Loras' propensity for those of the, uh, male persuasion as a possible turnoff for Tywin; but as discussed, in everything VISIBLE, Loras is actually quite accomplished and Tywin was fine with marrying Cersie to him despite the rumors because his appearance was noble and it would have cemented the houses. As long as people did what they were required to do and presented the image they were required to present, then Tywin was pleased; it's the reason he could recognize Tyrion's mental superiority while still loathing him and being unwilling to give him any public face with the family. As Tyrion said in the very episode, "All dwarfs are bastards in their father’s eyes."Really, the funny thing is that Loras and Margery are, in terms of public appearance and reputation, anyway, everything Tywin would have liked Jaime and Cersei to be. Loras is seen as an excellent tourney knight and is considered to be gallant, while Jaime is loathed. Margery is also much more popular than Cersei.
