Quote #7
Theon thought of seeking out the bodies of the two men he'd slain himself to see if they had any jewelry worth the taking, but the notion left a bitter taste in his mouth. He could imagine what Eddard Stark would have said. Yet that thought made him angry too. Stark is dead and rotting, and naught to me, he reminded himself. (38.Theon.18)
Theon's coming of age hits a bit of a snag in A Clash of Kings. He has two father figures in his life, Balon Greyjoy and Ned Stark, and both have a different understanding of what it means to grow into a man. Theon's mind is stuck between both, and as such, he can't come of age in a way that would please either father figure or himself.
Quote #8
The longsword was a lot heavier than Needle had been, but Arya liked the feel of it. The weight of steel in her hands made her feel stronger. Maybe I'm not a water dancer yet, but I'm not a mouse either. A mouse couldn't use a sword but I can. (39.Arya.20)
Arya's coming of age features her trying to figure out what kind of person she should be. She keeps comparing herself to various animals and things: a mouse, a wolf, a ghost, and a water dancer. She is basically trying on different roles to see which one fits best.
Quote #9
[Dany] hated it, as her brother must have. All those years of running from city to city one step ahead of the Usurper's knives, pleading for help from archons and princes and magisters, buying our food with flattery. He must have known how they mocked him. Small wonder he turned so angry and bitter. (41.Daenarys.22)
Dany's coming of age allows her to look back on past events and view them in a more mature light. Her brother, Viserys, was a jerk to be sure, but Dany's difficulties in Qarth help her understand why her brother became such a bitter person, showing how she has grown since Viserys's brutal death.
