Claudia was apprehended for attempted murder charges. Jeff was the one alerted officer Garcia of her arrival and Asia. He needs to make sure she cannot create a scene at the party.
They know she would come and create a scene at the party. Therefore they arrange to apprehend Claudia during that time, and it's a success. She's now history.
It's like nothing happened. The celebration continued. The guest from all over the world doesn't care who is the true heiress of Tan Corporation. What matters to them is who Jeff chooses to be his partner. From what the spectators saw, Joanna Tan is the right one just from her look alone.
After the big commotion, Albert Tan, Grandma Tan, and Sophia excused themselves. They needed to go to the Police station to speak with Officer Garcia and find out what's going on. She's still a family member in the eye of the onlooker; they cannot abandon her like that.
