The big difference was it was only implied in the first two volumes (though I've heard Millar confirmed it in interviews, I wasn't reading interviews at the time). In Loeb comics, it just smacks you in the face. And Wasp defends it as something modern and new-agey and Cap and his disgust over it is just him being a grampa.

> I am new to the msg boards and dont know if this has been covered yet? What about the relationship between these two? It was implied that it was more than brother and sister. I did think that was the best I have seen both of them drawn. Just was surprised by the adult implications I guess.
