I would still disagree. Someone apparently drank her blood which is totally out of pocket with seeing a knife on a table, honestly, and is not justified by "well there was a knife there".
Comparing it to a normal real world interaction where you expect people to just hang out and chat is ridiculous, if people just chatted it would be a totally failed set piece.
It's not an accident that she put a number of violent items out and had her assistants riling people up, something like "someone drank her blood" is exactly what it takes to make it into art history.
