Sympathy for the Demon - S5-E7
Corrected entry: Cole says Barbas can use his powers to become the Source, but in the episode "Womb Raider" they established that an aspiring Source needs to lay his hands on the Grimoire to become the source, which was hidden away by Leo in the Andes. (00:19:40)
Sympathy for the Demon - S5-E7
Corrected entry: When Cole drinks the power stripping potion, his powers go to Barbas, but in season 4's "Black as Cole," when Cole is hit with the power stripping potion, his powers just disappear, no one gets them.
Correction: We are talking about completely different powers that act in completely different ways - it's not the same as stripping his demon half from his human half.
Sympathy for the Demon - S5-E7
Corrected entry: There are many references in this episode to Phoebe using a power-stripping potion on Cole. But it wasn't Phoebe who used the potion on Cole; it was Emma, the fiancée of one of his victims. (00:15:15 - 00:16:25)
Sympathy for the Demon - S5-E7
Corrected entry: When Barbas posing as Leo walks down with Piper, she sees a memory of her as a child. When "Leo" asks what she sees she says "It's okay, I remember this". Little her in the memory was running down the stairs with a toy telling her grams that she loves it. Then her father Victor approaches and gives little Piper a hug, a demon magically appears and attacks them, little Piper screams and Victor protects her while grams says a spell. How can Piper says she remembers this if they never knew about magic at the time?
Correction: Grams has already been shown to have the power to erase memories. For example in That 70's Episode, Grams made it so that little Andy wouldn't remember being frozen by little Piper. That means that she could have made Piper not remember the demon.
Correction: Cole doesn't say this. After stealing his powers, Barbas mentions that he can use the amount of power to become the new Source. It isn't proved in the episode that it would actually work, as he never gets to the ceremonial part. Perhaps the Grimoire would have been needed eventually, or seeing the amount of power Cole owns in this season, the Grimoire might have not been needed anymore.
