The last time we saw Kai in the prison world, he was chained to a chair, forced to listen to a song he hates on the karaoke machine over and over. However, when Alaric pops into the bar during the recent episode, Kai is nowhere to be found. Instead, he has left a handy video explaining how he escaped. He even makes a reference to Damon, Bonnie, and Katherine in the clip! The moment is a fun callback to TVD season six when Kai left Bonnie a video on a camcorder explaining how he linked her life to Elena's.
