After talking about something that Kalea did not think was that important, she parted ways with Angela. She did not forget to return the money she had asked for as part of her agreement with Angela at that time. Kalea really did not expect Angela to ask to meet just to talk about Dariel and Zeline.
It felt like Angela no longer hated her. The relationship with the woman was slowly improving, of course Kalea was relieved and happy. Whether she should be grateful or not for the accident, but it is undeniable that it was because of this incident that Angela became contemplative of her wrongdoing. The recording that she had said before, Kalea had deleted. The goal was only to threaten Angela back, Kalea wanted Angela to stop hating her, that's all.
