Of course he took a more dangerous job. Mary did her best not to roll her eyes.
"Hard to kill and cocky as hell about it," she said with a smirk. She wasn't excluding herself from that. She'd seen more than anyone that she was mortal, but she'd also been pulled back from impending death often enough that she felt comfortable taking risks if it meant that others didn't have to. Of course, she also placed a higher value on the lives around her than her own. Which was a Winchester trait as well, for better or for worse.
That last question was definitely a loaded one. And it reminded her that she needed to tell him that Johnny was around. Nobody in the family was all that happy with Johnny due to what he was, but if Rob knew he was here, it might keep things from getting heated whenever the two ran into each other. Of course, she had yet to find him on the ship, which didn't sit all that well with her. She didn't trust that the aliens would let her keep him or anyone else for long.
"I think it's safe to say that I'm as sane and safe as anyone else on this ship," she said with a shrug. "We'll see how much weight that holds if something goes wrong." She glanced towards the ocean, and then back to her brother.
"You should know. Johnny was at the resort. Not sure if he's here yet, but I thought you should know that he might be around. Dean too. Still haven't seen mom or Sam though. Have you?"
It was weird to think of Rob's reality-of a world where her dad had died and her uncle Sam had raised her and had a son with her mom. But the how of it all didn't matter so much as the fact that they were related. And even if they weren't, he'd been there with her on this ride for long enough that he was important to her just for who he was and how they'd been there for each other.
