Charleston knew what he was doing was not right but he needed time to set things in place, Olivia was still in his house and he didn't feel comfortable just taking Emily there when he had not told Olivia yet about Emily and the fact that he was married to her, Olivia was still recovering and he didn't know how she would feel about it.
Also, he had to tell Emily as well that the woman he loved and the woman that made him marry her was back, she wasn't dead.
He never imagined he would find himself in this type of situation before, not only did he have to explain the current situation to this woman, but he also had to decide who he wanted to be with, and for the first time, he didn't know what he wanted.
He was confused and needed enough time to clear his head.
"I just need some time," Charleston replied.
"Time? I think it's best you tell Emily first, she is the one you are married to," Liam said. Legally, Emily had more rights in Charleston's life than Olivia.
