Spoilers for second half of season 8 from TVLine

As if the trust issues between the Winchesters, the return of Cas’ mysterious heavenly arc and Amelia’s presence weren’t enough, Dean and Sam will also deal with daddy complications when their paternal grandpa, Henry, time-travels to the present in a family mythology episode. “When you meet your father’s father, that brings up some of your father issues. In other words, what did your father’s father have to do with the way your father turned out?” previews executive producer Jeremy Carver. “A lot of that is explored head-on.” But it’s not all doom and gloom. Felicia Day’s Charlie Bradbury returns in what is sure to be a geektastic hour about live-action role playing.
