Good thoughts and good points but Harry hadn't given details of his life with the Dursley's. Taylor's just running off intuition and assumption at this point. Taylor would not murder petty civilians even if they are guilty of child abuse. And possibly most important of all Taylor wanting to make the Dursley's pay for all they've done is hardly a bad thing in my mind. Good for the developing camaraderie.
I would agree that Taylor just up and killing Harry's relatives does seem rather out of hand, and all the more in light of Contessa's parting words and Taylor's already established thoughts on how that sort of thing could just offer unnecessary complications, but there is definitely a possibility for Taylor to take a route of doing something or another that is very uncompromising.
This is Taylor at the absolute apex of her Skitter career. If the Dursley's try to cause a problem... well, one way or another, they won't, most likely, and indeed "one way or another". Taylor—
Skitter—is not especially the sort to let people stand in her way when they're being disagreeable with her own aims. She tends to actually be almost weirdly tolerant at the same time if other parties will be themselves tolerant of her priorities, but if others are at cross purposes with her or disinclined to be cooperative, they tend to serve as an example for Lisa's assessment there towards the end on Taylor's idea of negotiating.
If the Dursley's attempt to make a problem of themselves, Taylor being "diplomatic" at them can do a wonderful job of causing them to reevaluate things and come to a more convenient decision, or find that they can't do anything about it. If they don't want Harry and his "new wife" staying with them, and for whatever reason Taylor believes that the two of them do in fact need to stay there regardless of whether or not the Dursley's themselves are there, bullying them into deciding that they honestly really should drop everything and go on a nice long summer vacation could entirely possibly end up happening, or just as well the Dursley's getting evicted unless they just deal with it. If she has no desire herself to be there, however, she could instead just summarily turn right back around and leave and throw the Dursley's objection at Dumbledore or whoever as an argument trying to build a case for indeed not staying with them, though depending on the circumstances she may or may not also be accompanied by a trail of bugs filching the contents of their wallets on her way out.
Taylor's character opens up a lot of possibilities. If she
does take up a cause, she'll just categorically pursue it no matter what. If she doesn't, though, she just as well
could potentially be completely indifferent, or act completely indifferent regardless of actual preferences. She gave everything to save Dinah on sheer principle, but was also was perfectly willing to work with some decidedly unsavoury individuals to do what she felt simply needed to be done sometimes, and she didn't really let the past matter much to her unless indeed she felt it actually
needed to matter. With such a character, there's plenty of room for Taylor to decide upon a vendetta against the Dursley's to just be portrayed appropriately in the writing, be thoroughly dismissive of a petty triviality in the face of far greater concerns, or instead alternatively take a very calculated and pragmatic approach
similar to a grudgeful vendetta but as a means to an end for no further reason than its convenience due to Harry and the impact thereof.
One last thought I have before I go to sleep for the night
@Fencer, but seriously consider butterflying away Amelia Bones being killed during this summer before the 6th Year. Having a nearly blank slate character that is known to be stern but fair and competent around that works in law enforcement would be highly beneficial to this story I think. It was a thought that occurred to me right before I decided to head to bed, and I figured it's worth mentioning now before you write any more chapters just yet and I might've forgotten when I fall asleep. Her being around for that interview in the Observation room also makes a lot of sense. Hell it makes more sense than Dumbledore being there.
Mm. It could work. There are new factors in play. Those could be spun as causing relevant effects fairly straightforwardly, given the setup.
We have an opening for quite the kerfuffle in the Ministry over Harry's misadventures when he's such a high-profile figure of his connections and got married, but under very peculiar and potentially quite dubious circumstances, that further brought in a seemingly quite inviolably attached foreigner—and minor at that—of unknown background to sensitive matters. Meanwhile, Amelia Bones is, herself, precisely the person for which this could be written as her problem.
If her department is responsible for trying to wrangle a lot of the formalities and issues involved here, hey, maybe she just stays working late one evening and it happens that highly ambiguous and mostly undefined attack on her in canon
would have gotten her had she was home then, except she isn't, so it just doesn't happen. If the narrative calls for more justification for why the same thing doesn't just happen a different way, it can still be made to work easily enough. Amelia Bone's death could be held as some circumstantially-dependent affair such that necessary prerequisites with certain Death Eaters being available at the time or whatever can't pull it off later, or
try, only for changed circumstances to obviate her death still: maybe she was going to get around to improving her home's defences and just never got around to it before it was too late in canon, maybe Death Eaters who do it originally and would try again later after an initial failure get preoccupied with something else, or maybe they find that instead of staying at work late, she brought work home with her that evening, and Death Eaters have the unfortunate luck to run smack into Dumbledore or get Skitter'd. Butterflies can cause more butterflies.
