Last update, in case anyone is interested in who's the daddy.
Since Lancelot has brown hair and neither Morgyn nor Lei lei do I assume he's Simeon's son.

Lei-Lei managed to have another oops (still not trying for baby) and she was still seeing Morgyn.

Lei-Lei had twins...

And when they aged up they had the same colour hair as Morgyn.
Alleria and Iona (can't remember off the top of my head which is which).

Simeon caught Lei-Lei with Morgyn, so he called him out.

It didn't end well (he overcharged again, the actual duel didn't kill him).
