And it's true, it does sort of read like fanfic--"And then they all got married to each other's spouses! And had kids! And it was tragic, but the kids were cute, and had superpowers!"

The double marriage is indeed the crackficiest bit of the whole story; I don't even know how that was supposed to work. Now I'm imagining Eugammon of Cyrene spending way too much time on fandom-wank.

(The tradition in which Nausikaa marries Telemachos, however, makes perfect sense.)
