I saw it I finally saw it the episode were Leo tells Piper he loves her and she tells him and thinks he's dead and heals him awwwww it was so cute I was about to cry, I was so happy cause there was more Piper than the other episodes which is always cool ya know. here's a scene [Scene: Attic. Leo and Piper are laying on the couch together.]
Piper: I almost wish I didn't give you your powers back. Then you wouldn't be able to leave.
Leo: Me too.
Piper: So if Daisy's a White Lighter to be, doesn't that mean you used to be ...
Leo: Human? Yes it does. I was actually born right here in San Francisco. I had lived here all the way up till I went after the war.
Piper: You mean like Vietnam?
Leo: No. World War II. I had left med school and enlisted as a medic. I wanted to help save people not shoot them. The last thing I remember I was bandaging a soldiers head wound and I felt a sharp pain and the next thing I know I was floating surrounded by White Lighters. They offered me immortality and the chance to help special people like you. I never once doubted that I didn't make the right choice. Till I met you. Ever since all I can think is how I'd give it up and have a mortal life again to have a family, grow old with you.
Piper: Is that possible?
Leo: Yea, I can become human again, Piper, if you want me to.
Piper: Are you kidding? I want that more than anything I don't want to lose you again.
Leo: But ...
Piper: But then you wouldn't be able to help other witches or other future White Lighters would you? You couldn't save the next Daisy.
(There's silence.)
Leo: I better go. (They kiss.) I love you.
(He disappears.)
Piper: I love you too.
