Jason Markham is a character from the CBS Storybreak episode "Witch-Cat".
About Jason[]
Jason is the son of Mr. and Mrs. Markham, and the little brother of Gwen, but big brother of Deedee. He is a slim, Caucasian boy with brown hair and blunt bangs, has black eyes, and freckles. He wears a yellow shirt with a banded collar and long sleeves; blue pants; and white sneakers. At another point, he wears a blue, long-sleeved shirt with folded collar and an olive green cap.
When Gwen brings home her new pet cat, Rosetta, Jason and Deedee come to see them. They're excited about having a cat, but the pet Scottish terrier, Dinki, doesn't share that feeling. Dinki barks with concern and the parents wonder why he's acting that way, but Jason chalks it up to Dinki simply not liking cats.
Another time, Jason is in Deedee's room where Deedee brings Rosetta and they have a tea party. When Jason asks about having grape juice again, Deedee tells her it's only pretend tea. Rosetta looks out the window and sees Gwen and her friends coming to the house. Rosetta then heads to the kitchen to conjure up a tea party for them after Gwen makes a wish for one.
One evening, Jason picks up Rosetta to join him, his friend, and Deedee to play a game of Explorer, and they go to a cave. Once they get there, Deedee tells him they shouldn't be there in the first place. But Jason just tells her to stop being a baby and asks where else they're able to play Explorer. Rosetta goes antsy, desperately wanting to head back to the house and Jason's friend, who's pulling Rosetta by a leash, tells him that she doesn't seem so friendly. Jason says she'll be fine once they enter the cave. Deedee uneasily mentions the darkness of the cave and just as Jason begins to tell her what to stop being, Rosetta breaks free from the leash and is on the loose. She runs farther into the cave, and as Jason calls her, she falls into a crevice. The kids brought flashlights, but they still fail to notice where she went. The kids think she simply ran back home and giving in to Deedee's demand, they exit and head back home. Following Rosetta being rescued by Gwen, Rosetta mentions that Jason and Deedee's parents learned about the kids traveling to the cave, and they're get grounded until Halloween.
When Halloween night arrives, Jason and his friend are in their Halloween costumes, and they manage to frighten off, and fool Dinki. Rosetta tells him that it's just the two boys in costume rather than the real deal, but he isn't convinced. That is, until she magically has him and herself fly. Once they're above them, they spot the boys without their masks, walking on a sidewalk, trick-or-treating.
