"Back in the day, when my parents were being hunted down, it was Aunt Adelaide who saved their lives and brought them back to Mount Kahdas so my mother could stay there. You guarded the Northern Cold City for twenty years for her sake, and after my father went missing, you took great care of my mother as well," said Carson Flores with genuine sincerity, bending at the waist to bow. "Moreover, you and my father, Westin Flores, were fellow disciples and good friends, so as a junior, it is only right for me to call you 'Aunt'..."
Carson's words were heartfelt. He didn't consider any romantic entanglements his parents might have had; she had done too much for his father and mother.
Not to mention this life-saving grace which was very real, and as for the relationship between his father and Adelaide Bautista, it wasn't Carson's place to comment. He could only replace it with the term "fellow disciple and good friend."
