In "Things to Do in Seattle When You're Dead", Callum, along with members of the four demon bloodlines, were invited to enter the Seventh Circle Night Club to witness the execution of a young witch named Layla Chapman. During the demonstration, a demon acolyte represented the mythological Demon Overlord, who supposedly had risen to unite the demon clans and wage war against witches all across the world. Callum, however, questioned the Overlord's existence and left with some of his comrades. Moments after his departure, Layla was rescued by the Charmed Ones.
In "Careful What You Witch For", after she escaped from a group of Vagrants with Macy Vaughn, Callum tracked demon-witch Abigael Jameson-Caine to SafeSpace, Seattle. He mesmerized receptionist Swan to have her show him around the building. However, Maggie Vera and Macy realized he was there and concocted a plan to lure Callum down to the Command Center, where demonic powers were neutralized. He held Maggie at chokepoint and went down to the center. Abigael told him to take the Book of Elders, a tome that contained the most dangerous knowledge of magic. When he tried to take it, it shocked him flying several feet back. He angrily tried to launch an offensive power at Abigael only to realize his powers had failed. Abigael then used a pitch fork to lock him in place and vanquish him with Macy's help. Before his death, Callum said, "It's you, isn't it?" The phrase led Macy to question Abigael and later realize she was an enemy.
