A mature Jean Grey Wolverine fanfic often deals with complex emotions. Instead of just focusing on the surface - level attraction, it explores their deep - seated feelings like love, loyalty, and sacrifice. For example, a fanfic might show how Wolverine is willing to put his life on the line for Jean Grey not just because he loves her, but also because of his sense of honor.
One great fanfic could be 'The Unbreakable Bond'. It delves deep into the complex relationship between Jean Grey and Wolverine. The story is mature in the sense that it explores their emotional and psychological connection against the backdrop of the X - Men universe. It shows how they rely on each other during tough battles and how their relationship evolves over time.

Jean doesn't kill Raven in the comics. The comic plots are elaborate and diverse, and this isn't one of the scenarios presented. There are many other elements that shape the dynamics between the two characters.
