WARNING: If you don't want to know what happened in this episode, don't read this photo recap!
Bea and Calvin are visited by Aunt Nancy, a friend of the family. She’s got some bad news: the Dredge wants to kill the Hastings family. The good news? She brought sweets. The other news: she’s not related. She’s Anansi, a sorceress believed to have died a hundred years ago.
Calvin is transported back to that fateful and fatal night at the funeral home when the Hastings family suffered heavy losses at the hands of some mysterious forces. Oh, also that Isaac was the one who killed Arlo with a crossbow. Keeping it in the family!
Calvin submits to returning to his memoryland at the request of Bea and Aunt Nancy. He’s transported to the Alchemy Room, where Arlo has accidentally released an Infernal from its container. The Infernal is intent on Arlo's death.
But not if Momma Hastings has anything to say about it! She does battle with the Infernal, but it gets the better of her. And Aunt Nancy has slipped into a trance, unable to lift the spell. It’s up to Calvin and Tilly to put an end to this.
Tilly, suspecting something is up, snatches Aunt Nancy’s own mason jar from her. It’s got all her memories in it. Tilly demands Nancy tell her what she’s doing here, and she spills: she is trying to get the Hastings in a fight with the Dredge and trick him into thinking he can get the ring. During the fight, they’ll be able to kill the Dredge. At least that’s the idea.
Arlo begs his brother to kill him and defeat the Infernal before it can escape and wreak havoc elsewhere. So in the end…Calvin shoots his own brother with the crossbow. Woah. Isaac took up the crossbow to make it seem like he killed his own son, when in reality it was fratricide.
