When Lincoln returned, he told Sean some news.
"When I was taking Miss Joanna back, I did encounter some tracking. So, I suggested to Miss Joanna to go straight back home.
She agreed - because her father is currently working for the ocean shipping company, and there are two hired female bodyguards at home besides her mother. The security is basically guaranteed, so I came back."
Sean nodded, Lincoln did the right thing.
He then asked Douglas:
"Douglas, how are Charles and the others?"
"As you instructed, I asked Charles to apply for a flight route to return first. He should still be in the air now and will give us a phone call when he arrives on the island."
Even though the police don't know about Charles and the others at the moment, Sean doesn't want to take any risks with this.
If the police dig out Charles and the others' existence after several fruitless searches and create some issues, Sean's side would be passive.
