On the way back, Anna Cooke kept asking Yusuf Zuck who Wren Hicks was and how he could tell and so on and so forth. In short, she asked all the way, but Yusuf Zuck didn't answer her in the end.
He couldn't possibly tell Anna Cooke that there was a compartment in the bottle and that the words "Wren Hicks" were hidden inside, could he? So until he dropped Anna Cooke off at her home, he didn't say a thing.
Anna Cooke was angry but also speechless. Before getting out of the car, she huffed and puffed, claiming they were no longer friends.
Yusuf Zuck just laughed, watching her enter a military compound before driving away.
However, Yusuf Zuck had left, but Anna Cooke stopped short and took out her phone to call Miles O'Brien.
"Sara, what's up?" Miles O'Brien asked with a laugh.
"Teacher, let's go to Hangzhou tomorrow, and ask Malachi Hicks if he knows who Wren Hicks is, whether there's any relationship between Wren Hicks and Malachi Hicks. We'll take the bottle with us."
