@Wolfwand: No, I was just using an outside example of how being magically disguised as someone doesn't mean any child conceived while in that form would be the subject of the disguise's biological offspring.

Another example would be any character from any other fiction who has a parent that's a demon, god, or other supernatural figure, as I'm pretty sure that Hercules is Zeus' son despite Zeus having disguised himself as Alcmene's husband to lay with her, and that King Minos is also Zeus' son despite being conceived while Zeus was in the form of a bull.

If one needed an example from contemporary fiction, there's the example of Magnus Bane from the Mortal Instruments series as well, (SPOILER if you read the series and have yet to reach COHF's end) his father is the demon Asmodeus and he was conceived when his father disguised himself as his mother's husband.

The point is, in no fiction I've ever seen or read, has magical disguise made someone able to conceive in a surrogate manner for the subject serving as the disguise.
