Nycolas's Links
The one person in his life that Neal can't do without. He and Nycolas have been together since the day they were born and being such low ranking sons, it often felt as if there was no one for them except for each other. They have often shut the rest of the world out for one another, especially after Nycolas lost the ability to speak. Neal will defend him and care for him until his dying breath and he knows that Nycolas would do the same for him. They will always come back for each other, always find one another and a part of him hopes that when the time comes that they go together because he can't imagine a world without his brother in it.
Arya looks up to the pair of old brothers; her dreams as a child to be everything they are. As she grew older, the realization of what they've been through became more clear to her, but that has yet to stop her from learning everything she can from them, making it obvious she doesn't fully understand the consequences of the path they chose. No matter how hard they try and lose her, she always manages to catch up to them -- something that's her little secret. She looks up to them both as older brothers to her, and wants nothing more than to make them proud. Though she doesn't harass them all the time - hanging out with a couple of old men isn't exactly her favorite past time!
Henry thinks he's great! Of course, Henry thinks just about everyone is great. He knows Nycolas a little better than his half brothers, but not by much. He doesn't see some scary monster or the like when he sees him, though. He just sees his distant uncle and he wants to hear all sorts of stories from him (even though he's mute).
Casper doesn't know him very well. They're distantly related through marriage and honestly he thinks he might have met him all of once. He thinks he's an amazing warrior and fighter, but most of that opinion comes through stories and not even personal observation. He would probably like him just fine, but they haven't really had a reason to meet or get to know one another.
