Simon knew that even the most well-adjusted people had skeletons in his closet. When he was younger he'd been the nerd kid who got the crap kicked out of him if he didn't have his friends around to stick up for himself. He was the kid with the weird mom who claimed to see the future. And she did, for better or worse, and his mother was so proud of the fact that both her son and granddaughter were psychic too. Lucinda had so much she wanted to teach Tabitha, but Simon put his foot down. His daughter wouldn't have all that shoved down his throat like he had, as a child.
Of course, Charmander himself wasn't a threat. He boosted Simon's own abilities, thus making Simon a bigger threat. If Simon were to make a threat of himself, that was, which he wouldn't. Honestly, nothing was really worth that much of an effort. At Sam's question, Simon tilted his head to the side a little. Yep. Kid lived under a rock. "Elementals and witches," he said. "At least, those are the only people I've met with them." He paused. "I'm a witch." Pity he didn't really do the showy sort of magic that made people ooh and ahh, otherwise he'd prove it.
Seeing that Sam was sneaking closer, Charmander peeked up, leaning closer to Sam. I don't bite! the salamander said, all too cheerfully. And I make his magic stronger. Better. He might not say it but he likes having me around!
