The leader of the pack of Black Root officers that come aboard Lucy is the same one who was after Khlyen in the season opener. 

This episode has the most visual effects of all the episodes in the entire series to date, which includes Johnny and Lucy’s incredible spaceship dogfight!

Sarafin is played by Rick Howland who appeared in all five seasons of the Syfy series, Lost Girl, which was another creation of Killjoys creator, Michelle Lovrettta.

On set Lucy was voiced by writer’s assistant, Lisa Rose Snow, during the goodbye scene with Johnny. And there were several wet eyes in video village during the scene when Johnny and Lucy say goodbye.

The tree in Aneela’s vault was built by the production design team who sourced dozens of large trees to create one, giant, beautiful trunk.

Pree’s makeup was red in honour of Pawter "Red" Simms.

There were two gallons of the green plasma in the base of the tree.

Hannah did the entire Archive action sequence in her heels!

The cast had a tearful and heartfelt goodbye with Rob Stewart as we all said farewell to Khlyen.
