Once again, Claudia really wanted to help James in realizing his wish, to persuade Sarah to come back. But he also couldn't be sure if Sarah would accept all his opinions that told him to return to Singapore. Because Claudia really didn't know what had happened to James, nor to Sarah herself. He just wanted to try everything he could, so that his cousin wouldn't continue to be so immature. Even though he did, he also knew that if he were himself in Sarah's position at this moment, he might be able to think worse than what Sarah had done up to this point.
Actually at that time, Claudia asked James to stay in Hong Kong, for a few more days. But because James didn't get any meaningful clarity about Sarah's whereabouts in Hong Kong, James decided to just go back to Singapore. He actually felt very, very burdened, because he did not know Sarah's condition and condition at that time.
