The Scandal - S9-E2
Character mistake: Billy has second thoughts about selling his late sister's beach house to a developer who plans to tear it down and build a hotel. Billy tells Ben, "She lived the last years of her life here." But in part 1 of this two-part episode, it was established that the woman had lived in the house for only six months.
Answer: If it was ever found out that she was at Terry's house before he was killed, there's a possibility that a lot of people would have begun to suspect her of murdering Terry. By claiming that she wasn't, she was hoping that people wouldn't accuse her of the murder.
