Kids with issues I say! Less than 25 year old, still wet behind the ears!
On a more serious note. For Viraa, I'm thinking Julia wouldn't know what she is but have a good hunch at this point it isn't pure human. I also wonder about the other people's background, Atelai in particular and his partaking in a super soldier program. How much DO we know about each other?
If I had to say, Julia would have been pretty transparent about everything and has nothing to hide really, though she wouldn't openly talk about her own family and children. She'd acknowledge she has some but wouldn't go in the specifics.
EDIT: Eh, thinking of switching the avatar for Old Integra lol, seems fitting xP
