I have many thoughts about this and I can't make up my mind. We know that Hj is a witch, from a witch family, but what about sh? What type of witch is her? All I know is that sh is scared of her powers, and the way they can hurt her family. The weird things that happen around her already scared her brother she can't have them get hurt too.
Hj's familiar doesn't spend much time with her. They're connected through their souls so they can communicate in ways others can't, can hear each other's thoughts which is a lot bc Wy's brain never shuts up. Hj has learned to tune him out, she sends her cat to sh's house and asks him to protect her, look after her. It makes Hj feel better knowing that whatever happens a part of her soul is there with her best friend who she loves so much.
When Sh's powers manifest, Wy panics and Hj feels it like a zap to her brain. Everything after is a blur. Next thing HJ knows she's driving to sh's house, waiting by the window as she watches her try to run away.
"You can't get rid of me that easily" she says, and then they're on the road bc no matter how much Sh complains HJ is even more stubborn and she loves Sh, she can take her to the right coven that will teach her how to use her powers. HJ can protect her until then, can teach her everything she knows. WY complains the whole time. Sleeping in a car is uncomfortable until sh learns how to charm a motel manager into letting them sleep in a room for free. It's that funny little trick that lets HJ know just how powerful sh is, even without training. And maybe they were right in running away bc there are forces at play following them. (And yes, sn is sh's familiar)
