With the exception of a brief line by Hayley in the opening scene this is the only episode not to feature any members of the Smith family.
The Summoner's song to waken the Majestic is actually called "The Majestic" It's the first track from Wax Fang's album 'La La Land.'
Lyrics to the song sung by The Summoner to awaken The Majestic: A sight for sore eyes to the blind would be awful majestic It would be the most beautiful thing that they ever had seen It would cause such surprise, it would make all of their minds electric How could anyone tell them that some things are not what they seem In such disbelief, I thought I was asleep when I met you My heart liquified and I sighed, oh this must be a dream" If I forget to set the alarm and sleep on through the dawn, don't remind me I'd rather be dreaming of someone than living alone If you're searching the lines for a point, well you've probably missed it There was never anything there in the first place
WILHELM SCREAM: Heard when the Shapeshifter morphs into a fist and punches an Imperial Guard off the platform.
There are at least two references to the Star Trek franchise in this episode: one is a reference to the original tv series a blue alien with white hair (Andorian), and a shape shifter like one from Star Trek VI.
