Back at the palace, Cai Ling asks her auntie if she's gotten the pass to return to the mainland. She doesn't know which one to ask for, but she does know that Cai Ling wants a hostage. Cai Ling tells her that if she asks for a hostage, she should ask for the one that's most special to Cai Ling. She says that if they threaten Cai Ling with the hostage, he'll give it to her. She also tells Cai Ling that if Cai Ling refuses to give her the pass, she'll have to catch Cai Ling's son, whom Cai Ling thinks is a better hostage. She tells her auntie to knock on her door and ask her to help her. If she doesn' t want to help, then she can ask Cai Ling for the pass. But Cai Ling isn't interested in helping her sister. She's only interested in repaying her brother's favor. She wants to know why people still remember her even though Cai Ling has been dead so long.
