Ep 8. Obsession

In Highlander season 3 episode 8, titled "Obsession," Duncan MacLeod finds himself being stalked by an unknown assailant. The episode opens with MacLeod in his dojo, training with his sword, when he senses that he's not alone. He turns to find a woman watching him from the shadows, but before he can confront her, she disappears.

Over the course of the episode, MacLeod tries to piece together who this woman is and why she's following him. He enlists the help of his friend Joe Dawson, who runs a bar and also happens to be part of a secret society of immortals. Dawson is skeptical of MacLeod's claims at first, but soon comes around as the evidence starts to pile up.

As MacLeod investigates, he discovers that the woman who's been following him is Katherine, an immortal he knew hundreds of years ago. Katherine was once deeply in love with MacLeod, but he rejected her and she spiraled into darkness, becoming a ruthless killer.

Now, Katherine has returned, seemingly intent on finishing what she started all those years ago. She taunts MacLeod by leaving him messages and gifts, and makes it clear that she's not going to stop until she gets what she wants.

MacLeod is torn between his desire to protect himself and those he cares about, and his lingering feelings for Katherine. As the two of them face off, the stakes get higher and higher, and MacLeod realizes that there may be only one way to stop Katherine once and for all.

The tension builds to a thrilling climax, with plenty of swordplay and dramatic reveals along the way. It's a classic episode of Highlander that showcases the show's unique blend of action, romance, and supernatural intrigue.
