Thinking. It was an awfully convenient place for her to be thinking, wasn't it? There were a lot of other places to do all that contemplating at. Like their apartment. The Roadhouse. The complex. Anywhere but on the path that he had been walking, really. Not that Sam minded - he was actually all for Ruby being with him right now, since he really didn't have any idea what he was doing by way of house hunting - but it was unusual. Maybe she had left to meet him, but ended up getting distracted somehow? That was all Sam could come up with that came close to fitting a logical conclusion. Shrugging it off, Sam flashed Ruby another bright grin and leaned to the side a little, as if her question were completely unnecessary. "What am I doing?" He elbowed her playfully. "What do you think I'm doing? I'm hitting on you. What's a guy gotta do to get your phone number?"
Whatever it was that she had been thinking about didn't seem too pleasant. Sam would press her for details later, but first and foremost, he wanted to see her smile. The upset probably had something to do with Lucifer's most recent threat, but Sam didn't want Ruby to worry about it. Not beyond figuring out what they were going to do by way of their living situation. It was logical to worry about the apocalypse and all that came with it - Sam reminded her that they needed to be careful all the time, just as he went about researching every single day for anything worth using against the Devil - but they had just gotten married. Sam was still half terrified that Ruby was gonna up and walk the first chance she got if things got bad with Lucifer knocking at their door and, honestly, he wouldn't blame her if she did. He had even told her as much the other day. That didn't mean that he wanted her to leave and it sure as hell didn't mean that Sam wasn't gonna give it his all at giving Ruby reasons not to. Like this. Cheering her up. Showing her that he still cared. That they could still smile, even if it was just for a few minutes.
