At the same time, it wasn't like she hadn't expected this. After all what person would allow such an opportunity to escape in front of his eyes.
In fact, if Roy hadn't asked her for something like that, she might even think that the reason he died was that he was too stupid for his own good.
But she didn't expect Roy to be that vicious, as one look on his eyes was enough to confirm that he was serious and that he would truly kill her if she didn't find a way to prove her loyalty for the future.
She was trapped between a rock and a hard place, and no matter which side she picked she was going to lose something.
On one side it was her life, and on the other, it was her freedom. But since she had decided to gamble everything, she decided to pick the second.
Furthermore, it wasn't like she had much of a freedom at the moment anyway. Roy was her lottery ticket, she either won and become one of the wealthiest women in existence or lost and died.
