"Can I go now?"
Medea was clearly frightened by Daniel's sudden act of cruelty.
Watching Joseph's body slowly fall to the ground, she pressed her mouth shut and finally managed not to scream out loud.
Quick reaction, eh!
Fu Qian, on the other hand, nodded in approval, his face showing appreciation.
Daniel's action was something he could very much understand.
The situation at hand had clearly become unmanageable due to his presence.
The unspoken understanding between Joseph and Medea had lost all meaning with an additional witness.
Given their prior interactions, Daniel was obviously not confident he could silence Fu Qian right here; thus, how to wrap things up became a serious issue.
The key was that even if he gave up on killing, it would be difficult to earn Medea's trust, let alone get her to drop the matter of tonight.
In such a scenario, poor Joseph became the sacrificial lamb, exploited by Daniel for one last time.
