Nope Nope & Nope!! Was hoping it would be a great spin off... WOKE AF!! Utter & Complete BS to what we already know about John and Marys start. SAME story line as Season 1 of SN, Missing Dads. This is a Joke, Un original.
Does John know Mary is a hunter?
FyI Jenson if you read these .. when JW found out about Mary. being a hunter was in 1973, when Castiel (Misha Collins) sends Dean back in time in this fourth season episode. This is before the two are married, and before John even has Baby.. ( which tbh you should already know as you were in the dang show)
They tell Mary about an angel coming to kill her and John. While they are talking, John gets lured away by Anna and Mary comes to John's rescue. John finds out about Mary's hunting past and is angry she never told him.
As for Henry Winchester!
Henry Winchester went missing in 1958 when JW was a small child. fleeing from Abaddon (Abaddon infiltrated and murdered the elders of the Men of Letters. He was given the key to the Men of Letters headquarters, to be kept safe from Abaddon, which he took with him into the future in an attempt to avoid the Knight of Hell.) not in the 1970's
So the Men of letters ref and giving JW the Key makes no sense in this series and contradicts what we already know!.
and to top it all off The Actors just don't have any chemistry at all.. Cheers for Ruining what could of been a perfect spin off to pander to the Woke Bravo Bravo . it's a NO from me!
