Dad appears in Meat. As John is giving the teens some space for their reunion, a week before on John's birthday, he sees Dad through the window of his study. Dad is smoking a pipe and listening to his favorite jazz music. There's a kitchen timer set up on his desk. His window is slightly open, but he doesn't seem to notice John, and John soon walks away. The timer goes off just as John is using his retcon powers to zap away with the other kids.
In the Candy timeline Dad had been named Chief of staff by Jane. He is first when Jake tells Jane he sacrificed himself in order to save the human president from a rebel assault. There was no body for Jane to revive since the shot came from a rocket launcher and it was shredded to pieces. Jane quickly recovers herself after a small breakdown in front of her crew, and decides to launch a more direct attack on the troll rebellion.
