Could it be the last supper?
Boris Johnson will travel to Brussels for the first time in months on Wednesday night to sit and break bread with the EU Commission chief Ursula von der Leyen.
It is more than a standard diplomatic dinner.
It is possible that the encounter could be the moment at which the UK and the EU conclude that there cannot be a trade deal now, and that after decades of political and economic ties, efforts to say a polite political farewell have failed, with all the consequences that might entail.
The purpose of the dinner however is not to call a halt. But nor is the purpose to proclaim that a deal's been done.
