"Yep," he says. "They all turn the same way too." He wouldn't try to draw it out - he doesn't have a pen, for one, and two, getting it to look right could be a challenge. "It's not the only time I've seen it either - the symbol, not your tattoo." He shrugs, he isn't really clear if it actually means anything, just that it's an important symbol for the Hales. Like a family sigil.
