As they were laughing, Amelia's angry voice cut through the laughter and shut everyone up because she said, "Shut up!!!"
Everyone shut up immediately, so the communication channel became as quiet as a graveyard. This allowed everyone to hear what she wanted to say clearly.
She said to Greg, "What did you do?"
Seeing as she was as serious as a heart attack, he decided to tell the truth. So he said, "I might have attacked him. It was a joke, of course. But he took it seriously and thought that I wanted to kill him. He wanted to kill me for the prank, so I left in order to preserve harmony."
This wasn't exactly the truth, but it is the best truth that he can bear to tell. He is just too embarrassed to tell the whole unadulterated truth.
But what he feared came to pass. Amelia snorted and said, "Ivory, go and ask his subordinates what happened. I want multiple accounts, so I will know who is lying."
Before Ivory could acknowledge her order, Greg decided to step up.
