Lily was a little concerned at first. Charlotte would still suspect her because they had been besties for so many years. She even altered how she sounded and acted, which proved to be superfluous.
The only disappointment was that Henry appeared to be upset. He was angry because the woman he looked for was not Charlotte.
But it didn't matter.
He treated Charlotte differently because he thought she was the one who slept with him back then.
Knowing that she wasn't that person, he stopped treating her that way.
