TK cracks me up. I was laughing at pico de gallo... my Spanish is a bit rusty, but I think it means Rooser's Beak... so comparing Tyrion and his missing nose to a rooster's beak is just ridiculous.
Wiggs, dang it! Every time I think I'm mildly funny you come along and reveal the real joke. Carson, Leno, Letterman, et al have people who write their monologues. Would you consider writing my posts for me? I'd certainly get a lot more laughs.
Marv, I'm gonna try and make this quick. The full explanations may be found in other threads.
Lyanna died fifteen years before AGOT. Eddard did not take Jon to save Lyanna's honor, he took Jon to save Jon's life. If Robert knew that Jon was Rhaegar's son, then Robert would have killed Jon. (Remember Robert's decision to have Dany murdered?)
It appears that Lyanna, three of the Kingsguard, and presumably some servants were at the Tower of Joy. Eddard and his men (most notably Howland Reed) killed the Kingsguard. Eddard took the infant to Willa, a servant of the Daynes. Presumably Eddard returned Arthur's sword to the Daynes and presumably Eddard said his goodbye to Ashara the woman he had romantic feelings for before he married Catelyn.
Once Catelyn asked Eddard about Ashara, thinking Ashara was Jon's mother, and Eddard told her to never mention her name or Jon's origins.
This huge secret never comes out in Eddard's chapters. He does remember and dream about Lyanna. Eddard's mind is filled with images of Lyanna's bed covered in blood (mayhaps from giving birth), blue roses (Lya loved these flowers), Lyanna's words "Promise me, Ned" (I assume the promise is to keep Jon safe), and then Eddard pictures Jon.
That was very brief. The threads on Jon's origins will reveal dozens of pages of speculations.
Rohan, Welcome. Yes, Rorge is one scary guy. On your observation of specialized minor characters... Janos Slynt comes to mind. Yes. Yes, he comes to mind with his manner of speech. Yes, speech. His use of language is... ah... peculiar. Peculiar, yes! That's the word. Oho, Janos Slynt speaks his mind. Yes he does. None can say that the Lord of Harrenal does not say what he's thinking.
You know nothing! It is known. Just so. A man grown. An old done man. Trained and chained. Valar morghulis. Stick them with the pointy end. These and other phrases easily signify individuals and social groups. Marting uses idioms very well to develop his world.
