Even Leila looked at Lucas in astonishment.
She knew that he was the chairman of the Stardust Corporation, and through various clues, she had guessed that he was an illegitimate son of the Huttons, one of the eight top families.
But she thought that since he was an illegitimate son, the Huttons didn't recognize him officially. While he could still leverage the family's power in front of the other families, he couldn't do so when facing the two scions of the Waltons, a family of the same status as the Huttons.
After all, the Huttons would never go against a family of comparable strength and status for the sake of an illegitimate son whom they had kicked out of the family years ago.
Moreover, Lucas wasn't really Leila's boyfriend in the first place. They had only met twice and exchanged a few sentences. She had merely dragged him here to pose as her boyfriend to try and stop Roger's incessant harassment of her.
