"Jo?" Sam visibly relaxed when he caught sight of the petite blonde, glad to see her all in one piece and not dead. At the same time he could slap her upside the head for freaking them out. First not answering her calls, then not showing up for work? Not on.
Took you guys long enough.
"Sorry. Might've been just a little easier to get here if we knew where you were." He smiled at her. "You didn't answer your phone."
As Jo went on to fill them in on what they were dealing with--a succubus, right up Dean's alley--Sam was quiet and listened carefully. He was doing what he was doing best. He was taking what information she was giving him and applying it to the situation they had. "It explains the dead men and missing..er...appendages." Of course, when Sam spoke about what he was thinking he was talking to Dean. He was all for working with Jo, but he always told Dean the things his brain came up with first.
