Charmed, Season 1

Piper (about Leo) :
It just seemed like he wasn't telling me the whole story, like he had some secret he was afraid I couldn't handle.

Phoebe:
Well, that's his call. Assuming that he had a secret. Might not have.

Piper:
What are you talking about?

Phoebe:
Ok, ok, you don't have to beat it out of me. Leo is a whitelighter. They're sort of guardian angels for witches. And they're not supposed to get involved with witches, but Leo couldn't help it. He fell in love with you, and that broke all the rules and got him in all sorts of trouble. And even though he'll love you forever, you will probably never see him again.

Piper:
What? Phoebe, that's the most ridiculous thing I've ever heard. Oh, God. Don't be so silly.

Phoebe:
That's me, silly.
