Why not put a brief pause in this line. Doing so makes it come across as if he’s saying it with more trepidation:
“Sir, about the girl. They say that she’s dangerous, that she has powers…like yours.”
And:
“Her powers are only beginning to awaken. The longer it takes to find her, the more dangerous she becomes.”
Too on the nose??
Or:
“She’s only begun to grasp the fullness of her powers. The longer it takes to find her, the more dangerous she becomes.”
