While harming those she cares about, insulting her intelligence, and/or taking advantage of her might send her into "I will coldly try to undermine you"-mode, there's only one thing that will probably make her snap to the point her logic is completely blinded by fury, and that's getting in the way/harming her research/magic somehow.Â
This character sees magic and research as her sole purpose in life, so harming or taking that away from her is like taking a part of her soul. It might feel extreme, but magic was always an "escape" for her and something that offered her a motivation to live and something to do. Magical research is pretty much what keeps her together, she uses it to cool off and to build herself up. It's a bit ironic, that messing with her "structure" will make her completely collapse.
If she snaps, it will start off as extremely explosive and uncharacteristically emotional of her, however, once she has calmed down, she'll grow colder and begin to look into different ways to ruin the person. If this person has done enough harm she will happily attempt to bring them to absolute ruin and misery before she manages to finish them off.
Now that I think of it, there's another thing that has made her snap in the past, but she's far less dangerous in this case. Stupidity. If she or those she cares about happen to be put in harm's way because of other people's incompetence, she can be sent into an explosive fury, but not to the point she will want to physically harm the others (After all, she is aware of the fact stupidity/incompetence isn't on purpose) But she'll get extremely verbally abusive and cruel if she's rubbed the wrong way. This is the easiest way one can get her "bitch-streak" to show, even in situations she will regret later.
