Angst? What Angst?: Elizabeth Westbrook seems to have gotten over being kidnapped by a rouge state for two weeks pretty fast.
Moral Event Horizon: Martin is a somewhat geeky scientist who plays with cloning for petty reasons and continues to do so after his first cloning attempt for a school date ends up endangering the school. But he firmly crosses the line when he shows visible excitement about Count Von Brucken deciding to kill Elizabeth because she knows too much.
The Scrappy: Benjiro and Emily Kajiwara, Jenniffer/Control's parents, who are always trying to force their lifestyle into Luna's family, and never see themselves as wrong in anything, and basically refuse to see their fault in Control running away from the Kajiwara household in the prequel due to their controlling behavior towards her and blaming her when the family starts to crumble, respectively, even playing the victim card when they appear in the original series. Needless to say, their presence is nerve-grating for most readers, if not all of them.
What an Idiot: Emily. To elaborate, Luna goes missing (She was out on a mission) and when she returns, Benjiro starts berating Control and Andrew for not being strict to Luna sneaking out of her house, which starts an argument between the Kajiwara seniors, Control and Andrew, which causes Luna to have a huge meltdown, yelling "We're supposed to be family! Families are nice to one another. All you do is criticize and pick on each other. If this is family, then I don't want one!" and locking herself in her room, breaking down in tears. You'd expect Emily to lay off the criticism and shut up for once after seeing how badly it's affecting her grandaughter. Instead She keeps dishing out the criticism, telling Control "Well, you've made quite a mess of things." in the most condescending and passive-agressive way possible, which fuels the arguing even further, and Luna ends up running away from home because of it.
Martin's whole character is about this. Why yes, let's take an evil doctor's cloning research and continue with it where he stopped from so I can clone a smoking hot celebrity and not be a "Forever Alone" at the dance. It won't backfire horribly on us in the slightest.
