[Brown Rat]

Based upon the (admittedly small) sample of kids with powers that we've seen so far, it seems as if, when two people with powers have a kid, that kid has a power. I wonder if the powers make people with powers want to have potentially procreative sex with one another? (A selfish power gene.)

Or is it just coincidence that Nathan was successful seduced by Jessica, and now we hear that he also mated with Claire's flame-on biological mother? (Yes, Jessica was obeying Linderman in sleeping with Nathan. But, still.)
And Hiro hit it off with the powerful waitress--although I dunno if they had sex.
