Clara, the Doctor, and Christmas crackers
In The Time of the Doctor, and Last Christmas
Because every Christmas is Last Christmas. Time of the Doctor was 11′s last Christmas, and Last Christmas was Clara’s final one (not counting Twice Upon a Time). Besides the wonderful parallels of these scenes, both 11 and Clara see a close friend they lost for one last time (but only as a dream/hallucination), both age a lot, but are then young again. 11 is rescued when Clara asks the Time Lords for help. Clara is rescued when 12 asks Santa for help.
Now what was in Clara’s Christmas cracker in Last Christmas? We unfortunately never find out.
