Chris orbed into the attic. Paige looked up from the book. "Chris, you find anything?"

"Maybe... The Elders think They know who it was. Demon who did it…did you see the balls they got hit with?"

She nodded.

"What color were they?"

Paige paused. "White, I guess…they looked sort of like…light bulbs almost."

Chris nodded, running a hand through his dark hair. "I was afraid of that."

"What? What was it?"

"Innocence demon."

"Excuse me?"

Chris sighed. "He blasts his victims with innocence. Extreme, complete, total, all-encompassing innocence."

"I thought innocence was good."

"Yeah. When you're young. Or when it's a purity of spirit. Absolute innocence, though…They're losing knowledge, common sense. They'll regress more and more until they're infantile and lose their powers in the process."

"So what do we do?"

"What we always do. Find the demon and vanquish him."

Paige began flipping through the Book of Shadows. "Not seeing anything on him. Where do we find him?"

"Figures. He's never been stupid enough to attack a Charmed one."

"So there's no page on him, how are we supposed to vanquish him?"

"Not sure. But we can't just vanquish him with a spell. We need a potion. Fast. Their powers will stop working as they regress and they'll be more vulnerable."

Paige nodded and headed for the door. "I'll—"

Piper's scream sent the pair racing downstairs.

"What? What is it?" Chris asked. The concern in his voice turned to laughter as he entered the living room.

Paige followed him and laughed as Piper stared in horror at the wall. Phoebe and Leo sat on the floor, a scribbled mural covered the dining room wall.

"What the hell are you two doing?"

"Makin' the walls pretty," Phoebe said.

Leo smiled up at his wife. "We wan'ed t'surprise you."

"Think you did that," Chris said. "How come you didn't use paper though?"

Leo looked up at Chris, wide eyed. "We did but it's all gone."

Piper took a deep breath. Leo held up a blue crayon. "See? I made the f'owers blue 'cause Phoebe said blue's your fav'ite."

"That was nice of you, Leo, but how about we get you guys upstairs?"

"Don' wanna," Phoebe said and turned back to the wall, scribbling with a red marker what appeared to be a flower.

Piper stepped up and took the marker from her. "No! Phoebe, you have got to fight this! Now act like a grown-up!"

Phoebe's eyes filled with tears as she burst into tears.

"You're a meanie!" Leo shouted.

Piper threw her hands up in frustration, turning to Chris. "What did I do? Every time I talk to them, she ends up crying and my husband tells me I'm mean."

"They're reverting back to children. You can't just yell at them to stop. They see that as grown-ups being…grown-ups."

"So you're saying I should treat my husband and sister like children?"

Chris nodded and stepped past Piper, crouching down to Phoebe's eyelevel. "Hey, Pheebs."

"Hi," she whispered.

Chris stroked her hair and smiled. "I know Piper was being a little cranky, but how about we go upstairs and play up there?"

She looked at Piper, then Chris. "Is she coming?"

Chris glanced over his shoulder at Piper, giving her a mildly apologetic look. "No. We'll let her stay down here."

"Could Leo come too?"

"Sure. Leo, you wanna come with me and Phoebe?"

Leo looked up from his piled of markers and nodded.

"Chris, carry me?"

Piper rolled her eyes as Phoebe reached her arms up for Chris. He picked her up.

"Come on, Leo," he said. Leo hopped up and grabbed Chris's hand. He stuck his tongue out at Piper as they passed her.
