Rob's brows furrowed as he watched the strangers. He'd heard about them both, neither were alive in his world. They'd never made it for different reasons. He had to trust Mary, and that was both easy and difficult. She wasn't his Mary, yet she was Mary Winchester.
"It's okay." The youngest Winchester nodded to Max, who wasn't just giving the approaching woman a look and touch. He looked ready to hit and run. The tortured woman was thankfully out cold. They had no idea what the killer looked like, and this new female might have sent the prostitute into hysterics. No one wanted or needed that.
"No Mary. Johnny went after her. She's," a tilt of the head to the woman Max held, "a prostitute. No help. She's too far gone. But, we figure their attacker is a woman." He glanced at Max who knew that look and who just nodded.
"I know which way he was headed." Rob gave the man in the fedora a nod and a grim smile before starting off. Max would look after the prostitute. Whatever was going on wasn't for him to get involved; it felt too much like family business, and Max wasn't exactly family.
