The epigram, "Thy rod and thy staff they comfort me," comes from the Bible, the 23rd Psalm, in the King James version. It is end of the fourth verse, which begins: "Yea, though I walk through the valley of the shadow of death, I will fear no evil...."
This will be the final ever episode of Grimm
The Hebrew word for "Thank You" in the credits is written erroneously from left to right instead of right to left.
Kate Burton (Marie Kessler) and Mary Elizabeth Mastrantonio (Kelly Burkhardt) were credited as special guest stars at the end of the episode. Originally scheduled to be available for two days of filming, Kate Burton and Mary Elizabeth Mastrantonio ended up being only available for one day due to severe weather; all their scenes were then shot in the one day they were on set, including stunts.[3][4]
