Bill's job meant a little heavy lifting, it meant getting out into the hot sun and he looked the part. He was a little precious about his hair, took special care of it and guarded it against his mother's wand, but he was happy to just pull it back when he needed to. The smile lit up his face and he let the flame extinguish from his wand tip, yes Klaus seemed harmless enough and the flirting really set Bill at ease.
It was more than innocent flirting though, there was a real offer in Klaus' lingering glance and the way his gaze went up and down the length of his body. It was nice, Bill was flattered and it was a good distraction.
He tucked his wand into his pocket before he offered Klaus his arm. "Phone? I mean I know what they are but I don't know how to use it," Bill admitted. "And I'd be open to a drink at your place, if you're offering."
