Fridge Horror: Going back means the ending of you and everything that makes you you save your soul. The only way you will be even remembered is at the Past Lives Pavilion where your next form(s) can get clips of what you were. So, when Daniel is told he's going back, it means goodbye Daniel, forever.
Tearjerker: The final act: first you're crying because it's Daniel's Darkest Hour when Lena pins Daniel for not facing his fear within Judgement City, making him lose the trial, and then tears of joy when Daniel proves her wrong by facing his fear on the bus back to the life by running all the way to Julia's bus.
What Could Have Been: The male judge states that the scenes he will see will be in 3D, while Daniel is amazed by the scenes. Originally, the script called for the scenes to be played out as if in VR, but that was dropped and was just rendered as a television screen.
