While eating breakfast, Anna was shocked to hear what her brother just said to her.
"You told them about my relationship with Kyle?" Anna specifically told her brother that he should not share that information with anyone until she and Kyle are ready to announce.
Her father still hasn't approved of her relationship with Kyle, they both want her father to be the first one to approve their relationship since he is the hardest one to persuade.
"My mouth probably slipped when I was talking to Lucia over the phone, and she might have told Ophius about it." Aaron didn't even try to lie about it. He totally forgot that his sister told him to keep his mouth shut about her and Kyle's relationship as long as it is necessary.
The reason why he suddenly blurted that information out to Lucia is that Lucia kept on asking and asking about his sister. He had enough of her pestering him, so he said what he should not have said.
