"So don't think I'm joking..."
Hearing the words that are coming from Rex's mouth makes Margaret quiver while holding the katana stabbing her chest, she regrets acting confident and bold to Rex.
It's true that Daniel Burton is her father, but she's nothing but a bastard daughter.
Even if Rex killed her right here right now, Daniel will probably attack them later but he will not be reckless since his wife doesn't know about any of this.
Rex can just use that card against Daniel if he really had to,
But since Daniel is a business partner and also one of the good head families in the 25 Golden Crest, Rex decided to honor his request but Margaret is pushing the line.
With a meek voice, Margaret then said, "I'm sorry for acting out of line..."
"Please forgive me, I can't leave my children alone so please don't kill me", she added pleadingly.
