Mr. Stitch was Molly Thomas' childhood imaginary friend and protector. He came to life when Molly needed his assistance coupled with an ancient symbol which helped the creature come to life.
When Molly was little, she created an imaginary friend with green hair and his body was made out of her baby blanket. Mr. Stitch was created to fill the emptiness that Molly felt as her mother was away working most of the time.
Combined with Molly Thomas' anger and the mystical device planted on her person, Mr. Stitch was animated in the tunnels beneath Washington DC to take care of Molly's impulses. Sensing Molly's fear, the creature follows the feeling until he accidentally trips a ward which activates the security system in the Vault, closing every entrance to and from the vault. Later, Molly feels a great hatred for her teacher, Mr. David. The creature goes to the school where he attacks the teacher. Not long after, Molly realises that she is mad at her mother. As Diana and Jenny leave the house, the ward on the wall glows green. Mr. Stitch appears and advances on them. Jenny shoots it but it shrugs off the bullets and knocks her aside. Diana shoots at it as well but it keeps advancing. Jenny grabs a shovel and knocks it back, and they get inside. The creature grabs Diana's throat but the women manage to slam the door shut, breaking its grip. They then go back outside but Mr. Stitch has disappeared. The sun has just set, and Diana explains that in Molly's stories, Mr. Stitch went to bed as sundown. At the abandoned park, where the creature is staying, Diana and Jenny arrive. As Jenny begins the spell, Mr. Stitch steps out and Diana tells Jenny that she'll distract it. She shoots the creature and runs into a nearby funhouse, and Mr. Stitch goes after her. The creature smashes through the walls and knocks her down, but Jenny arrives and smashes it over the back with a board. Mr. Stitch knocks her aside and goes after Diana... just as Molly, Jake, and Alex arrive. Molly apologizes for bringing Mr. Stitch there, and says that she should have talked to Diana. Jake and Alex take Jenny to the spell circle. Molly tells Diana that she doesn't like it when she keeps things from her. She admits that she's angry with Diana, and Diana says that she can let it all out. As they hug, Jenny sets the blanket on fire and completes the spell. The sparks surround Mr. Snitch, and Molly says goodbye to it as it disappears from existence.
