Each person in the coven has their own abilities, but they still try to learn and embody more over their lifespan.
Cate herself tries to act like she doesn't have powers, but, unfortunately, she does. She hs visions. Most of the visions only come to Cate while she's asleep, but she occasionally gets them while conscious as well. She doesn't talk to the other witches about it, rarely even discussing the topic with her own mother. She doesn't want to acknowledge that they happen.
Cate prefers to lean more into the nature-based abilities she tries to learn. The learned powers make her more comfortable; she doesn't feel "different" from everyone else because it's not something she naturally possesses.
