"Are you on guard against me?" Rosier asked, watching Kyle's movements as she tilted her head back slightly.
"Yeah." Kyle did not deny it and answered bluntly, "As a righteous wizard, what's wrong with being wary of a Dark wizard from decades ago?"
"I thought we worked well together this time."
"Only temporarily, and it wasn't cooperation. At most... well, we just had a common enemy." Kyle said. "Also, have you forgotten that we were enemies just a few months ago?"
"But you're still perfectly fine now, aren't you?"
"That's only because I was cautious enough. It had nothing to do with you."
As Kyle spoke, his eyes remained fixed on Rosier's every movement.
Fortunately, though Rosier found it rather regrettable, she was not overly fixated on that alchemical item capable of blocking the Killing Curse.
Aside from Kyle watching her from the side, she had also given it some thought and concluded that the item did not seem as useful as she had imagined.
Being able to block the Killing Curse sounded immensely tempting, but in reality, it was not quite so appealing, because Grindelwald seemed to have no use for it at all.
After all, his opponent was Dumbledore, a wizard who had almost never used the Killing Curse... at least, Rosier had never seen Dumbledore use it.
The same went for the Cruciatus Curse and the Imperius Curse.
Even at the height of the war seventy years ago, Dumbledore had never used the Unforgivable Curses.
That was probably why he could be called the strongest White wizard.
It had been that way before, so there was naturally no need to say anything about now...
Thus, Rosier had no reason to take an unknown risk just to seize an alchemical item that was of little use to Grindelwald.
