Sun's storyline takes up the first 20 minutes of this episode, the longest any episode of the show has focused on an individual character.
While in bed, Amanita Caplan is reading Slade House by David Mitchell. The story revolves around characters who have the ability to travel into other bodies, a similar theme to Sense8. Mitchell is also one of the writers credited for the series finale script, along with Lana J. Wachowski and Aleksandar Hemon.
The aptly named episode, "You want a war?" Is a question/threat spoken by Will. He speaks this to their main nemisis as a promise that their cluster is going to rain hell down on Whispers and his people.
