It's Mary Kenwood's last taste of December because Kira already scheduled her death on the 10th of the next month.
...She's standing in her underwear
Looking down from a hotel room
And nightfall will be coming soon.
Oh my, my! Oh hell, yes!
You've got to put on that party dress.
It was too cold to cry when I woke up alone
I hit the last number and walked to the road.
Last dance with Mary Jane,
One more time to kill the pain.
--Mary Jane's Last Dance by Tom Petty
