I feel bad for the tea merchant guy, he most likely got executed (since he is probably a commoner) for deceiving the nobility + ‘poisoning’ them
I feel like she should have thought more carefully on how to deal with him after confirming his crime rather than just take him to court which would 99% get him executed for something that isn’t grave enough to get that sentence. I doubt she would be even happy about it if she knew what happened to him afterwards, especially since she was a former 21st century person
