Phoebe

 "Phoebe is performing an ancestral séance to learn about a curse that threatens Paige. But instead of her grandmother, a puff of red smoke appears and… Cole steps out.

But it’s not Belthazor. It’s not a demon. It’s just Cole, as he was the day they first met.

“I don’t belong to any world anymore, Phoebe. But I’ve been given a brief chance – to help you break that curse. After that… I’ll be gone forever.”

Piper protests. Paige is wary. But Phoebe… agrees.

The three of them join Cole in a closed dimension – where souls are trapped and regrets live on.

To break the curse, Cole must sacrifice his last memory of Phoebe.

He smiles: “If that’s the price for you to live… it’s worth it.”

This time, as he fades away, Phoebe doesn’t cry. She smiles – for the first time in years. Because she knew he was truly at rest."
