"Never make a deal with a Fae - you might end up getting entangled with more than what you bargained for." Aldric's warning rang clearly in Islinda's head, and that was the reason she stared at Andre hesitantly. Was it worth getting into a trade with him? She already knew that a negotiation with a Fae was binding.
However, Islinda couldn't remain in the dark forever. She had to uncover the truth that had been hidden away from her. Moreover, Andre was not like Aldric with his sinister ulterior motives. Furthermore, she was not naive enough to enter a deal with a Fae without being specific. Her time with Aldric had taught her to be cautious.
She said, "Fine, I'll grant you the deal on the condition that whatever favor you collect doesn't compromise my physical well-being or morals."
This way, he couldn't hurt her or force her to harm anyone, at least physically. She trusted Andre had compassion, unlike Aldric, but that didn't mean she couldn't be careful.
