Phoebe, Piper and others in “The Good, the Bad, and the Cursed”

Phoebe

Dad doesn't know that Leo is a Whitelighter.

Piper

Well, I've been meaning to tell him, but considering Mom had an affair with her Whitelighter, I didn't think he'd be really receptive to the idea.

Leo

Piper, he's gonna kill me when he finds out.

Piper

Oh, don't be ridiculous, you're already dead.
