I find the amount of guilt you say Jaspin has about what he did to Elizabeth interesting.  Now it makes me want to think, does Elizabeth feel guilty about burning his house down?
I'm gonna venture out on a limb and say no.

Actually, it was kind of the other way around.  Making a family is what pushed her to mostly get over him.  Raising Jonathan gave her something to focus her love and attention and womanly instincts on.  It was a great distraction.  But there were probably moments when she couldn't quite get around talking about it, like when lil human Jonathan looks up at his new mother and asks why he doesn't have a father to speak of like most of the other kids.

Okay, I see what you mean.

It was from her wildest days, really doing whatever she wanted without regards for the wellbeing of the clan.  After she kept ignoring the safety of the clan, was chased out of a town, and went back to the clan shell-shocked and a bit meeker, Elizabeth broke her finger off for a lesson and permanent reminder of what'll happen if Nadya crosses a line again.  She did something similar to Bela.  A not-so-subtle reminder that Elizabeth will done out to let her wards know, without doubt, that if they cross the line again and endanger them all, she [i]will[/i] kill them.

Needless to say, Nadya has since taken it down a notch.
