Changes

[[Sergei]] tells [[Castiel]] he was given a vial of [[Gabriel]]'s [[grace]] in exchange for a potent cloaking [[spell]], that Loki used this spell to mask his presence in Monte Carlo. Castiel comments that he knows this, a reference to [[13.18 Bring 'em Back Alive]] when he had read Gabriel's story about shacking up with porn stars from where the archangel wrote it on the walls in his room in [[the Bunker]]. The cloaking spell also explained how Chuck believed Gabriel to be deceased and said He was unable to resurrect him in [[11.22 We Happy Few]].
