After last week's episode ended with The Sentinel wanting to kill Mary Sibley, this week's episode of "Salem" season 3 followed Mary's son the devil as he spared the life of his mother and proposed a punishment that was worse than death.

Since the devil could not afford to kill his mother, he told The Sentinel that he could punish Mary without having to kill her.

The Sentinel entrapped the soul of Mary in a box. As he put her whole face inside the box, her soul got locked up in a mental dungeon, where she was tortured several times.

Elsewhere in the episode, Cotton Mather's wife and witch Anne Hale allowed Cotton Mather to go alone to a town meeting in a bar. When the refugees started to storm in, the people became worried, thinking that they were in danger. They asked Cotton to get rid of them.

Cotton used the meeting as an opportunity to get rid of Brown Jenkins. By drinking some herbs and alcohol, he was able to vomit the creature out and squish it to death. However, Brown Jenkins was immortal so he quickly found his mistress Anne.

Just when Cotton was about to get rid of Anne's rat, the townspeople woke up to see the sky drenched in blood. Captain John Alden then sensed that the devil and the native Indians they tried to kill but didn't die had something to do with it.

Meanwhile, the politicians refused to let Alden leave Salem with men because they wanted him to stay and protect them. As a result, Alden decided to take just one brave boy and find out what caused the skies to be drenched in blood.

Alden and the boy arrived at the town and found it burned down. They saw Sebastian Marburg give the Indians and the French a locket that brings death and destruction.

It was learned in the episode that it was the devil that enlisted the Indians and French to fill the town with frightened men and women, so they could take the blame once the town is destroyed. He knew that the destruction of Salem would ignite a war that would last for 100 years, leading to the entire humanity's destruction.

Elsewhere in the episode, Mercy and the Magistrate agreed to a deal which required the latter to please the former sexually every night in exchange for an antidote that would stave off the poison that Mercy had administered to him.

The end of the episode saw Isaac getting some solace from a girl he once saved, after his claims of Mary killing men got dismissed.

"Salem" season 3 airs every Wednesday, 9:00 p.m. on WGN America.
