As you can probably imagine, this is not going to end well for Dorothea.
Corakinus returns hell-bent on revenge, the Cabinet of Souls is finally put to use, and the Governors' employers, the true Big Bad of the series, are revealed.
Tropes that appear in the episode:
- Back from the Dead: April dies with the Shadow Kin when Charlie uses the Cabinet on them, because of her linked heart — but suddenly comes back to life in Corakinus's body, to the surprise of the other characters.
- Big "NO!": Twice by Ram. First is when his father is killed, and the second is when the last Rhodian soul comes charging towards him.
- Cliffhanger: The season ends with multiple examples: the reveal that the Governors are working with the Weeping Angels, preparing for "the Arrival"; April dying and resurrecting in Corakinus's body; whether Quill will survive her pregnancy; and what exactly happened to the last Rhodian soul.
- Cool Key: Dorothea's key to the Governors' room, which is made up of the Roman numerals 'MXVII'.
- Death Seeker: After being infected by the Shadow Ash, Charlie prepares to sacrifice himself by using the Cabinet on the Shadow Kin. However, at the last minute, it didn't happen (possibly due to Quill saving him.)
- Despair Event Horizon: Charlie crosses it when he's forced to kill April, pushing him to use the Cabinet of Souls.
- Final Solution: Charlie finally decides that he'd rather exterminate the Shadow Kin than have them keep wandering around the universe slaughtering people.
- Five-Second Foreshadowing: The members of the Board of Governors turning their backs on Dorothea when the Chair sentences her to death is the only forewarning given to the appearance of the Weeping Angel.
- Foil: Ram and Tanya. Both characters lose their single parent in this episode (Ram's father, Tanya's mother), and both want Charlie to use the Cabinet of Souls. However, whereas Ram changes his mind when April reminds him that she could die as well with her heart being linked to the Corakinus, Tanya angrily ignores her friends in favor of teaming up with Quill to force Charlie to use the Cabinet in the name of revenge.
- Godzilla Threshold: After the Shadow Kin return to Earth and start killing the loved ones of the main characters, the possibility of killing them all is further emphasized.
- Hijacked by Ganon: The Governors turn out to be a Path of Inspiration working for the Weeping Angels.
- Impaled with Extreme Prejudice: How Corakinus kills Ram's father and Tanya's mother.
- Insert Song: April's song 'The Lost'.
- Kill Him Already!: Charlie is told to do this to the Shadow King and then the Shadow Kin.
- Killed Off for Real: The Shadow Kin, Varun Singh and Vivian Adeola.
- Kill Us Both: April tells Charlie that Corakinus will kill everyone regardless, meaning he is forced to shoot her to kill the Shadow King.
- Left Hanging: Barring the possibility of Class being convalesced into Doctor Who proper for a wrap-up, the show got cancelled and all those shocking things that happened in this episode (the deaths of loved ones, Quill's potentially deadly pregnancy, the Rhodians being sacrificed, April becoming Corakinus, the Weeping Angel cult) are up in the air. One could be tempted to break out in a rash from all the irresolution.
- Mass "Oh, Crap!": Charlie, Matteusz, Ram, Quill and Tanya have this when they discover that April's soul has inhabited Corakinus's body after both of them died due to their linked heart.
- Neck Snap: How the Weeping Angel killed Dorothea, resulting in an Exorcist Head.
- Oh, Crap!: Dorothea freaks out when the Chair sentences her to death — and given the executioner is a Weeping Angel, it's understandable.
- The Reveal: The Governors work for the Weeping Angels.
- Sequel Hook: A conspiracy of humans working towards welcoming an Arrival of Weeping Angels to Earth?
- Shoot the Hostage: When April is held by Corakinus, Charlie shoots her to kill him.
- Synchronization: When Charlie shoots April, the Shadow King dies as well due to their connected hearts.
- Voices Are Mental: April is now resident in Corakinus's body, but she still sounds the same.
- Wham Episode: Let us count the ways:
- Corakinus returns, having retaken his throne, and plans to kidnap April and slaughter the entire population of the Earth. He murders Ram's father and Tanya's mother, contaminates Charlie with shadow ash and plans to keep killing until all his enemies are dust.
- Because of this, Charlie eventually feels that he has no choice but to use the Cabinet of Souls to destroy the Shadow Kin. He does so, and April dies along with them, but Quill saves Charlie.
- April mysteriously comes back to life in Corakinus's body, possibly because of the last Rhodian soul.
- Oh, and the Governors actually work for the Weeping Angels, and were planning to use the Cabinet of Souls to bring about some kind of arrival involving them.
- Wham Shot: The Governors have turned their backs on Dorothea, she starts to panic, and the camera sweeps around the room before she turns and, well, see the page picture.
- Year Inside, Hour Outside: The Governors' room.Dorothea: We manage time in here. You won't even know I'm gone.
- You Have Outlived Your Usefulness: The Governors execute Dorothea for not guessing that Charlie would use the Cabinet of Souls on the Shadow Kin — because they wanted to use it for their own purposes.
- You Killed My Father: Ram wants the Shadow Kin dead after they kill his father. Tanya wants them dead for killing her mother.
- You Said You Would Let Them Go: Corakinus fully intends to kill everyone even if he is allowed to take April.
