Ethan Johnston was walking in Afterlife when Jiaying stopped him. She asked how he was, and he told her that Gordon would be dropping him off in Prague for a backpacking trip.
Johnston was dropped off by Gordon, who returned to Afterlife. However, HYDRA leader List was tracking Gordon's appearances and located Johnston, kidnapping him for experimentation. Johnston later died in the thirty-seventh hour of experimentation.
As an Inhuman, Johnston had the genetic potential to gain superhuman powers after undergoing Terrigenesis.
