In some fanfictions, Sam tells Jessica about hunting when she starts to notice strange things around her. This often leads to a series of events where Jessica discovers her own hidden abilities related to the supernatural world. It's an interesting take as it gives Jessica a more active role in the story rather than just being a bystander to Sam's life.
A good one should have a believable reaction from Jessica. Since she's a normal person being thrust into this crazy world of hunting, her shock, confusion, and then acceptance (or not) need to be well - written. For example, she might initially think Sam is crazy but then see evidence that makes her change her mind.
