Prue and Piper were in the kitchen eating chocolate-chip cookies when Leo orbed in. He pulled up a chair in between them, and took a cookie while they stared at him expectantly.

"Oh, you had a question?" he teased them.

"Yes, Leo, we had a question," Prue replied. "What did the Elders say about Kritt?"

"The same thing Kritt said, pretty much," Leo told her. "We can trust him. The Elders think it's a good idea to let him move in and protect you."

"See, Prue?" Piper said. "We had nothing to worry about."

Prue sighed, resigning herself to what her brother-in-law had said. "I still don't like this, Leo."

He put a hand on her shoulder, and took another cookie as he stood up. "Just relax, Prue. Hey, if it'll make you feel better, I'll keep an eye on him, okay?"

Prue nodded. "Thanks, Leo."

He smiled at her, then gave Piper a kiss before going upstairs to tell Phoebe and the guys what the Elders had said.

"Okay, you can stay," he said grudgingly to Kritt. "But the Elders don't completely trust you, and neither do I. One wrong move, and I'm taking you Up There. The Elders will deal with you then." He paused before adding, "And if you hurt Prue, then screw the Elders. I'll deal with you myself."

Kritt held back on his sarcastic comments, sensing that Leo was completely serious, and nodded. "Fair enough. But I'm telling you now, I'm not going to hurt Prue, or any other member of this family. Now look, what we need to do is find out exactly what happened this afternoon. Who attacked Prue, and how? Did your Elders have any thoughts on that?"

"They said they'd look into it," Leo replied.

"Fine," Kritt said. "They can 'look into it'. In the meantime, Cole and I are going to get some actual answers."

"Wait," Phoebe said, putting her arms around Cole. "He doesn't mean that you're going Down There, does he?"

Cole nodded. "We have to, baby. It's the only way to find out who went after your neice."

This subdued Phoebe, but only slightly.

"I'm going, too," Leo announced. "I don't want to leave you two alone Down There."

"You can't all go," Phoebe argued. "One of you has to stay here, for Prue, in case something happens again."

The three men looked at each other for a long time, silently debating.

"Cole stays," Leo finally said. "I don't want to leave Kritt alone with the girls, and I sure as hell don't want to let the both of you run around by yourselves Down There, telling God-knows-what to God-knows-who."

"She doesn't trust me, either," Cole pointed out, speaking of Prue.

Leo sighed. "I know. But right now, she's more afraid of Kritt, and I promised her I'd watch him, so that leaves you. Just don't upset her, Cole. She's had more than enough stress for one day."

With that warning, he and Kritt orbed and blinked, respectively, down to the Underworld.

Cole looked at Phoebe. "So what do we do while they're gone? Just wait around?"

Phoebe shook her head. "You are so not getting off that easy. I want you to go make peace with my sister. Right now. I want her to trust you, and it's not just because I'm in love with you this time. It's for her own good, now. She's not going to let you guard her if she doesn't trust you, and she needs all the protection we can give her."

Cole sighed, and nodded. Phoebe led him downstairs to the kitchen, where Prue and Piper were still at the table.

"Hey, Piper, can I talk to you about something - in private?" Phoebe asked. With her eyes, she gestured to Prue and then to Cole.

"Sure," Piper said slowly, not quite certain that she wanted to know what her little sister was up to. Phoebe brought her out into the dining room, where they could watch Prue and Cole without being seen.

"Where's Leo?" Prue asked, watching Cole cautiously.

"He orbed down to the Underworld with Kritt to do a bit of fact-finding," Cole answered. "He told me to look after you."

She stared at him coldly.

"Prue, I know you don't trust me," he said, taking a seat across from her. "But I really am good now. How can I prove it to you?"

Prue sighed, her expression softening just a little. "I don't know. I don't think you can. I've accepted that part of you is human and trying to be good, and I've even accepted that you're in love with my sister. But the evil is still there, still inside of you, and I'm never quite sure whether or not it'll come out. Maybe I can learn to trust you, in time, but for now... Just don't hurt her, Cole."

Cole balked. "I'd never hurt Phoebe, not even as Belthazor. I hardly use my demonic powers at all, let alone against any of you-"

"That's not the type of hurt I was talking about," Prue interrupted. "Phoebe loves you, more than you can possibly know. Demon or no, just don't hurt her."

Cole nodded slightly, getting up to leave.. "I won't."

Prue looked away. As much as she hated to admit it to herself, she really did believe him.
