Tilly Harper

Tilly Harper appeared as a quasi-suspect in Hocus Pocus (Case #23 of Supernatural Investigations). She later made minor appearances in four more cases in Supernatural Investigations.

Profile
Tilly is Gwen's 13-year-old sister. She has green eyes, freckles and short red hair in a bob. She wears a pale yellow shirt with a white flower on each side of a beige collar, as well as an orange hairclip with a fuchsia and orange flower. It is known that Tilly owns a black cat.

Hocus Pocus
Mid-investigation, Gwen and the player were forced to file the former's mother, supernatural hunter Dolores Harper, as a suspect. Dolores was accompanied by Tilly, who told Gwen that she missed her. Dolores told Gwen that she had brought Tilly to the Hocus Pocus Museum in order to educate her on the dangers of the supernatural after she learned that she had befriended a Wiccan classmate.

After arresting Agnes Leek's killer, Dolores informed Gwen and the player that Tilly had gone missing from the museum. Per Hope, they tracked Tilly to a train station, where she revealed that she was trying to escape from Dolores' control. She begged Gwen to let her live with her. Exasperated, Dolores relented and allowed Tilly and Gwen to live together, although she predicted that Tilly would be knocking at her door in no time.

The Third Degree
Mid-investigation, Tilly wanted to come along with FBI Agent George Mathison, Gwen, and the player to interrogate her mother. Unfortunately, Gwen refused to bring her, saying that they wanted to talk about grownup stuff.

Death at a Funeral
Mid-investigation, Tilly showed up in Priya's lab, helping the latter keep an eye on the unconscious Hope. Luke then asked Tilly to run along because they wanted to talk about grownup stuff.

To the Lighthouse
Mid-investigation, when Gwen and the player entered Ben's lab, Tilly showed up, asking Ben to let her see the corpse. Gwen then asked Tilly not to bother him due to her being underage to look at the corpse before asking her to stay at the camper. She then went to stay at Hope's camper.

The Hunted Hunter
Throughout her mother's murder investigation, it is noticed that the Harper sisters were saddened. Mid-investigation, Tilly reported that Gwen was having a fight with crazy vampire Bathsheba.

After discovering the killer, Tilly requested the player's help to find the diary Dolores had left while breaking into Gwen's trailer prior to her death to cheer Gwen up. They then found the diary, which (per Felix) proved that Dolores was struggling to reconcile with her daughters. Tilly and the player then showed the diary to Gwen, helping her realize that her mother cared about her all the time. Later, Gwen asked Tilly to go back and stay with their brother while they were en route to Mississippi for her safety.
