He'd stepped out just for a few moments, he'd been about to send Peter a message saying if he wanted him to make a run at the grocery store when he'd noticed his .. sister's message and had gotten caught up in that. She was such a pain. Already, she was such a pain. He wasn't quite sure if it was the sibling bond already forming or because who her parents were. Both his mom and dad were that stubbornly persistant, especially when it had to do with him avoiding them. The thing about his sis-Mel was that she had this combination of his dad's optimism and, apparently, his mother's impatience. He couldn't win either way.
He'd placed his PDA down for just as second, both exasperated and irritated by her. When he'd picked up back again, he'd noticed her comment. If it had been anyone else but a member of his family, he might have let it go (though Chris knew better than to leave matters up to chance). However, she was a member of his family. And worse, she was Piper Halliwell's daughter. If she said she was showing up. She was going to show up. Chris left whatever he was doing and orbed straight to his aparment, more to Peter.
He orbed in right during Peter's attempts an explanation. "You don't have to explain anything to her." Chris snapped. More at over Mel than at Peter. Though, couldn't have not been nice for once in his life and leave her at the door? "Your definition of warning? First of all? Sucks. Second of all, isn't funny ... or cute. And if you touch me, I'm orbing you into the lake."
