Jaime is now ensconced as Commander of the Kingsguard. He reads the big Kingsguard history book. Barristan Selmy (who was booted out by Joffrey and is now helping Dany) seems to have had a very distinguished career, and is still going pretty good for a bloke in his 60s. Jaime's entry is rather paltry, as usual he is underappreciated and misunderstood.
He has an all hands meeting with his staff. Boros Blount is useless and craven and stomps off in a huff after being told to taste all of Tommen's food. Osmund Kettleblack has appeared out of nowhere and Jaime is suspicious of his background. Where did Cersei find him? Ser Meryn Trant gets told off for obeying Joffrey too much and beating Sansa for him. Too right. Jaime wins the chapter with "If Tommen wants you to saddle his horse, obey him. If he tells you to kill his horse, come to me."
Balon Swann seems like a decent bloke and quite useful. The only problem with him is his family ties. Jaime asks what he would do if he had to strike down his brother to save the king. "On my sword, on my honor, on my father's name, I swear ... I shall not do as you did." Well played, Balon. Well played.
Loras Tyrell, the flower knight who once gave Sansa flowers and now thinks she killed Joffrey, is a cocksure teenager just like Jaime was. We learn that his brother Garlan Tyrell wore Renly's armour in the Blackwater battle and that's how the whole Ghost of Renly thing came about. I wonder if Tywin knows about this and therefore, a few chapters ago, was referring to Petyr "finding" Arya by giving someone a false identity. Sansa? That would be weird. Loras also thinks Brienne killed Renly but Jaime manages to instill some doubt about that and sends him off to question her.
