It is pretty abnormal for someone to message a seller like this. It shows they are trying to get something out of you. I would hit the no reply required message. Then i would hit button reporting the buyer as being intimidating and the other button to ask amazon to investigate this transaction and only respond to questions related to did the box go to this person's address and do they want to return it. This is not a social media. This is a store. You buy something. If you don't like it or the condition, you return it. you don't start up a convo about the provenance.
