Prue eyed her sister, knowing the distress she was in. She'd just gone through this with Piper back home, she could find a way to help her through it again here. "I know it'll annoy you with me and Phoebe saying this, but just relax. Doing your best to stay relaxed is a key to you getting a hold of this power." Being Ms. Fix-It, Prue wanted to just fix everything for Piper right in that moment, but she couldn't, and while that frustrated her, she kept that feeling to herself.
But what she could do was explain why they were here and what was going on. "Here, let's sit down." Nothing she had to immediately say required them to sit, but it would be easier. Especially when she got to the tougher things to explain. Taking Piper's arm gently, she didn't want to accidentally cause her to blow something up, she led her to the couch and pulled her to sit with her. "There's a demon, Lilith, who wants to unleash Lucifer and the biblical apocalypse on Earth. Basically, in order to do so she has to go around breaking seals. I have no idea how many there are, but what she's done with breaking seals causes people from other worlds to be pulled here. But we were pulled from different times in our world. It was May 2001 for me when I showed up here, and for Phoebe it was 2004, I think. Right now it's January 2010." She kept her eyes on Piper and was really wishing Phoebe was here right then. After all, Phoebe was an empath and had a better knack for feeling how Piper was reacting inside. Prue briefly thought that she should hold Piper's hands, just to keep them from moving suddenly.
