It just occurred to me last night that clarifying Tarvek's name as Aaronev Tarvek Sturmvoraus; was another subtle way of showing how bound he is by his lineage. The part of his name that is distinctly his own is surrounded by his father's name. It all goes with his theme of being hidden/hiding.

Hmm. That sounded more profound when I was thinking about it.

Anyway, in contrast Gilgamesh's name is not only not his father's name; but clearly comes from his mother's people and is most definitely his own and not a family name, at least in Europa.
