Dude, you're telling me things I already know, re: Lucas & Julian.
I've little doubt there are tons of Julian Luthor embryos in cold storage just waiting to grow into a thorn in Lex's side.
Tess wouldn't be Tess if she wasn't a at least a little
bitter. It just so happens that Tess' mercy
generally outweighs her spite. That's what makes her more of a hero than your average Luthor.
