I like the look that Barn and Julia exchange when Elizabeth tells them about her vision of Cassangelique going up in flames. Maybe Julia is trying to reassure herself as much as everyone else when she insists that everything is okay. And it is, for the time being, now that Elizabeth is home. Carolyn's pride in her mother's strength of will is very touching. Nice work by NB and JB.
Barn has a good guess as to why Carolyn's bracelet repelled the creature, but he isn't talking.
Of course, if Elizabeth DID have that vision of Cassangelique getting dragged back to hell, why didn't the spell break there and then? Because the writers didn't want it to, I guess.
