But putting that side, you could go and claim this is a case of Alien Bizarre Sexual Dimorphism and she's actually a young female sanghelli.
Funny points if it turns out to be the daughter of the Sanghelli that Reisen feel in love with and he's actually a married man who has problems because the silly reisen tries to hit on him not realizing he's maried, so lil sanghelli-tan needs to help daddy and mommy by killing the stupid hypothenuse.
*edit* Nevermind decided to refresh my memory about "that" episode of Halo Legends, and they did have the human like female sanghelli, ironic, since my memory of it was full of average sanghellis, either I subconsciously wanted to forget the blatlant B.S.D. or "Prototype" and "The Odd One out" took over the majority of my "Halo Legends" memory out of how awesome they were.
Unless we find out that she's Lez Ol's daughter from yet another wacky sex encounter of a time on which Lez OL was willing to experiment with males. . .disregarding the species. . .
