During her stay, Viv and Cory are playing with light-sabers until Raven and Chelsea come home from school. Shocked by her energetic behavior, Chelsea asks Raven if that really is her grandmother; this offends Viv, who only likes being called by first-name basis. She then pranks Cory with "dinner", which is really a fake skull, and Cory decides to pay her back. Raven introduces Viv to Chelsea, explaining that she has a date later on. Viv then goes into her purse, to hand Chelsea a dress, which she thinks would look better.
The trio then head to Raven's room to help Chelsea get dressed, and Viv recalls a time when Raven was sitting with a “real serious” look on her face; when Chelsea asks if Raven was having a vision, Viv explains that Raven was actually using the bathroom (which embarrasses Raven a little). Cory then enters the room, intending to pull a prank on Viv by placing a whoopee cushion on a stool; however, Viv sees this coming, and tricks him into sitting on there instead.
The next night, Raven and Viv are camping out in the living room while roasting marshmallows, and Viv notices Raven's downward demeanor. Raven confesses that she hates her visions, as they make her feel isolated and a freak. Viv, understanding how she feels, shows empathy towards Raven, and how the visions put her in a lose-lose situation. This prompts Raven to realize that her grandmother is also a psychic. She showcases her ability by telling Raven that Cory is attempting to prank them with water balloons, as they speak. She explains to Raven that her powers are a gift, and despite the troubles they may cause with her friends, they're still her friends, and won't go away. She then tells Raven if she ever needs to talk, she can always call her.
She is later mentioned by Raven in "Don't Have a Cow". Raven receives a vision in which Chelsea accidentally eats a hamburger, leading Raven and Chelsea to go through Viv's old trunk, where they see all the supernatural possessions she owns (e.g. tarot cards and a book of potions, spells and incantations).
