I heard they were shooting in Montreal
which was standing in Austria, 1938...
"Zero Hour" takes place in the present day of Chicago and back in time to France and Germany in 1938.
Hmm! Time travel or flashback? Maybe they should coordinate with Grimm
on the whole evil magical Nazi artifact thing.
It might go back even further than that. Originally, the show was described this way:
His search leads him on a dangerous journey around the world collecting clues that will unlock not only a spectacular mystery surrounding the Twelve Apostles but also questions about his own identity.
Dr. Greene as the Thirteenth Apostle?
