Of Course

Theron continued to meditate in complete silence, his thoughts arranging themselves.

He had experimented quite a lot in this last month before coming up with this method. He knew well that there was an enormous hole in his story, so how could he casually allow it to be exploited?

What he wasn't sure of was whether Burne would be able to sense his curse mark in its diluted state or not, but he had made a bet that the Thistles didn't have a complete understanding of the methods of Daggers of the Night.

After Rouge shattered his robes, he already knew that he had won.

If they had the methods of Daggers of the Night, Rouge would be able to sense the curse mark without having to use such a crude method.
