Arriving at the police station, Finn Chandler accompanied Serena Sullivan to record her statement, and the two recounted the events of that night in detail.
Serena Sullivan made three points about the incident:
First, Ethan Grant was originally supposed to marry Zoe Quinn, but it later turned into her;
Second, Claire Sullivan and The Joyce Family wanted to introduce her to another partner, and this banquet was meant to create an opportunity for her to meet Young Master Grant;
Third, it was Zoe who invited her to the banquet, and it was also Zoe who pushed her into the room.
Connecting these three points, it was Zoe's attempt to steal Ethan from Serena, deliberately orchestrating Serena to be in an empty room and then instructing Young Master Grant to enter and commit an act against Serena.
Coupled with Young Master Grant's statement, no matter how much Zoe cried or acted pitiful, she was unable to do anything.
