He doesn't get to find out exactly what she apparently fights with, and that whistle means nothing to him (it's probably nothing of consequence, anyway.) But she is charging at him now, enraged, and he much prefers that over her flinging things at him like a monkey. Qilby holds back a smile. Good -- the taunting finally got to her, and now he can put his ability to keep her at a distance to actual use. Patiently he stands there, a sitting duck, until Apollo is less than two yards away from him before making his move-- conjuring a portal between him and her with the barest flick of his fingers before a grander sweep of his arm throws up the exit portal leading out and upwards, higher above everyone's heads.

And then, he proceeds to juggle her.

With each portal she exits out of, he dispels the previous one and throws out a new one for her to fall in until he's got a regular performance going on for the party (and any spectators, Deathwing included.) It's not even about hurting her at this point; it's more about making a spectacle of her for making a spectacle of them. No Blacksworn will look at her after this and think her leader material.

"What were you saying just now? I didn't quite catch that!" he crows up at her. His eyes are off the ground, attention focused up on his juggling-- but what's he got to worry about now?
