Piper knew that Wyatt was right that she was over-reacting, but she just couldn't stop being so furious. She was so stressed about almost all of the kids being over in London that it was affecting her mood to the point where she could seem either Bi-Polar or PMSing. Taking a few deep breaths, she calmed down enough to at least not seem angry, though she was still steaming inside. Not risking moving her hands in case she accidently blew something up again, she nodded at Isabella. "No, stay. This is...important. We need to at least work out who did the attacks." Cleanching her hands while her arms were still crossed, she turned towards Wyatt and sort of leaned to one side.
"Wyatt, that's different. She's their whitelighter, so she has no reason to tell me. But you bring a random girl in here I've never met, show her Excalibur, and then kiss her in the attic, or at least that's how it seemed when I walked in." Piper was still steaming, but was able to keep it under control. "It would have been nice to have at least met your girlfriend before you started showing off."
Actually becoming amused because her emotions were going out of whack, she turned back to Isabella, keeping a sraight look on her face, visibly trying not to smile. "Now, I'm sorry I reacted so badly. It's just that I'm so incredibly stressed because I'm worrying about all the little ones over in London. It's whacking out my emotions. Let's start over. My name's Piper Halliwell, and I'm Wyatt's mother."
