The Veronica Mars vet previously appeared in the Season 8 episode “Everybody Hates Hitler” as the grandson of a member of the Judah Initiative, the secret group of rabbis formed to fight the Thule Society. Rose’s character reappears in this season’s fifth episode, which, not so coincidentally, also features the return of the Thule Society.
“[They] want to enact their master plan and bring back Hitler,” showrunner Andrew Dabb previously teased to TVLine. “Sam and Dean are going to fight Hitler, and that’s opening up some interesting doors for us in terms of just doing some more crazy stuff.”
