For Thanatos, his days were a comfortable routine. He'd work, and go home to Lyra. Every so often he'd get pulled to do his duty, but that was far and few between. He didn't mind. It gave him more time for family, and to fuss over his twin.
He'd had an early shift today which meant he'd be home at a decent time and he could see if Lyra felt like going to the park. He almost didn't spot the young mortal until he saw the flash of red hair and a car that was perhaps going a bit too quick. He thought she didn't notice.
Without really thinking about it he moved forward to grab her by the waist and pull her back, out of the way of the car and back on the pavement. Once there he released her, "Are you alright?" Out of pure instinct he looked around for his sisters, but then looked back to the girl.
