You've heard the lady... Not that you have any choice, but it is always polite to ask. And Illaila is almost always polite, especially while strangling her prey with its own guts, but I digress.

So yeah, Illaila seen right after her work. Looks like things got a little... messy and there seems to be one, rather unlucky subject left that just happens to hear that question from the title.
Anyway, you can clearly see she is a professional and perfectionist - barely any stains on her dress, even though she had to kill several people who had very poor (or excellent, depends on point of view) timing.
Of course, she will vanish before the reinforcements arrive. She will probably just run straight to her main target, hidden under veil of her mighty illusions and pretending to be his lover, scared after witnessing the slaughter. And then... The blood will be spilled, slowly.
