David Cameron came to Edinburgh to show that he cares deeply about Scotland remaining part of the UK.
And passionate he most certainly was - using almost unparliamentary language as he urged those who want to use the vote to get rid of the "effing Tories" to think again.
By the end of a question and answer session at the Scottish Widows office in Edinburgh, he was glassy-eyed and there was a catch in his throat.
He pleaded with the hundreds who had come to hear him speak in the central foyer of the huge steel and glass building that "coming into the final days... please be in no doubt the rest of the UK is watching and listening, we are holding our breath. We care passionately about this united nation and we really would be desperately sad to see it torn apart."
Despite the passion he looked calm and relaxed throughout the carefully controlled event, which stood in contrast to Alex Salmond's walkabout on the streets of the city at the same time.
Some of those listening and asking questions were also clearly less than impressed with the Conservative leader's emotional appeal.
One woman tackled the Prime Minister on his terminology and whether or not his pledge of extra powers could really be called "guaranteed".
Another asked if all MPs would give up their proposed 10% pay rise to show their commitment to Scotland.
She also asked if the Conservative leader could give her a timetable for the withdrawal of Trident from Scotland, not in the event of a Yes vote, however, but if Scots back a No next Thursday.
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
