The question made it impossible for the lawyer to keep poking into Akira's business. Moreover, he was a little anxious to tell Akira the news that he had received quite some time ago. In truth, even though he referred to Akira as Helen Brown's daughter, he knew the backstory.

"You know that your mother had a twin sister, and she was not a good person." He began.
Akira thought it was a little ironic for him to say that because they both knew that her mother was also not an angel. But again, the degree of badness could be argued.
