Sam was actually relieved that Bobby had taken it upon himself to arrange the boot camp for those who were looking to learn defensive techniques. While he and Dean had promised to take people with them out on their hunts every now and again, there was only but so much that the two of them could really do. Additionally, there was only but so much that Sam himself was willing to do while trying to juggle his own personal life and his search for Lilith back and forth. So having this opportunity to bring these people out here to Bobby's place was one that he was more than appreciative about. Not only did it make the training process a lot easier, but it also made it more simple for Sam to get away when he needed to. If something about Lilith came up or if he just needed to breathe, he could do so without having to worry about leaving people with Dean. Normally that wouldn't be a problem - Dean was usually pretty good with people. But in his emotional state as of late, Sam didn't want to take any chances. He didn't want to give his brother more than he could handle. He had already made things worse when it came to his own situation with Ruby, Sam certainly didn't want to drag things on from there. Dean, too, had his problems. So having the extra help was really a great thing on both their parts.
After having spent the morning helping set things up, Sam decided to take a break. He walked the familiar path to Bobby's kitchen, lugging a bag of rock salt over his shoulder as he walked. Dropping the bag onto the kitchen table, Sam looked up to find his brother hanging out by the refrigerator. That in itself was far from surprising. Dean had always been a big eater. The unsettling thing was the dazed look that Sam found on Dean's face before Dean had noticed the fact that Sam was in the kitchen as well. For a moment, Sam couldn't help but wonder what his brother had been thinking about. Hell? Buffy, maybe? What?
"Toss me a bottle of water, would you?" Sam leaned against the kitchen table, brow furrowing in concentration as he tried to figure out exactly what was on his brothers mind. That was a far more difficult thing to do as of late - compared to before, where reading Dean was like opening a book and glancing at it's pages - but Sam sometimes got it right. "Looks like things are going pretty well so far," Sam said, folding his arms over his chest, "Bobby is kinda awesome." Sam smiled faintly, before he added, "You doing okay?"
