"Leo, you did all you could."

"Who are you? I don't care, go away," Leo said angrily, not even turning to see who had entered the room.

"Leo, you did all you could," repeated the stranger. "This isn't your fault. You can't blame yourself."

"I let her die!" Leo shouted. "How is that not my fault? I'm her Whitelighter, I'm supposed to heal her, guard her, save her!" Finally whirling around to confront whomever it was who'd dared intrude on his grief, Leo glared at the young man standing before him. "Who the hell are you, anyway?"

"You didn't let her die. She was dead when you got here. You couldn't have saved her, the Source saw to that. The deal that was struck exchanged one life for another. Prue knew that, even though you didn't."

"This is the third time, and I won't ask you again. WHO. ARE. YOU?" Leo demanded.

"My name is Andy Trudeau. I grew up with the Halliwells. I fell in love with Prue when I was, I don't know, six, maybe? We lost touch, but then when she moved back to the manor, we got together again. I was a cop. She told me her...'secret,' and I freaked out. And then a demon killed me," Andy explained.

"So you're a Whitelighter now? Lemme tell you, don't waste your time," Leo said bitterly.

"It's not a waste of time," Andy replied. "You saved Piper, and the bond of love you and Cole each have for the sisters let him save Phoebe, too. You've done so much good. You can't give up now."

"Yeah, what do you know? I've been doing this a lot longer than you have. And if you're a Whitelighter, why don't I know you?"

Andy looked away. "I'm not exactly a regular Whitelighter. I've been given a...special assignment."

"I guard the Charmed Ones, hadn't you noticed? What are you talking about, 'special assignment'?" Leo demanded.

Andy shook his head. "It's not for you to know...yet. But you will, I'm certain of it."

"Oh yeah? I'm certain I won't. I quit," Leo said angrily. Glaring at the ceiling again, he shouted, "You hear me? I QUIT! You wanna break the Power of Three after everything they've done for you, fine. I QUIT!" he bellowed.

Andy didn't even flinch. "You can't quit."

"Well, I just did," Leo snapped, heading toward the door.

"You're just going to walk out on your wife? And your sister-in-law? Leo, they need you now more than they've ever needed you before," Andy said.

"Well, They should have thought of that before letting Prue die," said Leo, motioning upward.

"Leo, it was her time," said Andy softly. "It was her time. She knew it, she understood, she accepted it. You have to do the same. The Charmed Ones' destiny isn't over. It's changed, but it isn't over."

"Don't you get it?" cried Leo. "There are no Charmed Ones anymore! The Charmed Ones are three sisters. One of those sisters is dead now, because I wasn't fast enough, and the Power of Three is gone!"

"No, it isn't," Andy countered.

Leo looked at him in shock. "What?"

Andy glanced around. "I'm going to show you something." With a wave of his hand, he conjured up a crystal ball. "Look inside."

The swirling mists inside the crystal cleared, revealing --

"Patty?" asked Leo. Andy nodded. Patty was talking to someone; Leo recognized him as Sam, Patty's Whitelighter. The mists blurred and cleared again, and Patty was shown again, visibly pregnant, as three little girls played inside the manor. Leo shook his head, as if to clear it, and blinked rapidly. "What --"

"Just watch," said Andy.

A new scene appeared in the crystal ball: Patty giving birth. The baby arrived in a swirl of orbs. Sam wrapped the child in a blanket and handed the bundle to Patty, who was crying. She kissed the baby's head, handed her back to Sam, and turned away.

The next scene in the crystal ball showed Patty and Sam orbing into a church, carrying their daughter, talking to a nun. With a final kiss from each of her parents, the child was handed to the nun, and Patty and Sam orbed out of the church.

Once again, mists swirled over the scene, clearing to reveal a pale young woman with dark black hair. Her image blurred and faded after a moment, and the crystal ball turned pearly white.

Leo turned to Andy, dumbstruck. "Is she --"

"Another sister? Yes. Her name is Paige. They'll find her soon. The Charmed Ones have a greater destiny to fulfill than you or I can imagine. They aren't finished yet, not by a long shot. But you're not supposed to know any of this. I'm sorry to have to do this to you..."

Andy sprinkled some memory dust over Leo. "It will be okay, that's all you know for now," he said quietly, and orbed out.

Leo blinked. He was standing in the middle of the living room, and wasn't quite sure how that had happened. The last thing he remembered was kneeling on the floor, raging against the Elders. He still felt grief, but his rage had subsided, somehow. With a heavy heart, he started up the stairs to join Piper in bed. In the morning, when she had rested and finished recovering from the injuries she'd sustained while fighting Shax, he would tell her about Prue. Best to let her get one more night of sleep before continuing her destiny, he thought to himself.
