The advent of Partygate, as it has become known, was on 1 December last year. That was when the Daily Mirror first revealed that Covid rules may have been broken by the very people who had made them.
Five-and-a-half months later, we've reached another big moment, because for ages people round Westminster wondered what might happen if the prime minister got another fine. Or so many he could paper a wall with them.
Some are wondering how he managed not to accumulate one or two more fines.
But we now know that isn't going to happen. The Metropolitan Police's role in all this is done.
You might be reading this boiling with anger about what went on. Or perhaps you are past caring, or never really cared at all.
But this mattered: morally to some, legally to others and politically to plenty, and it still does.
