Much to his own surprise, Sam was visibly relieved when Molly stepped out of the truck. If his perception was anything worth trusting, the girl looked just as anxious as he felt. What embarrassment he felt, he conveyed with a sad, almost apologetic smile. He didn't even think to introduce himself, and he too was wishing he would have just let Molly handle this. The smile didn't falter, even when Molly mentioned that they had all been burned, and Rogue alluded mutation. It wasn't like Sam ever knew what it was like to be normal, and Rogue? She seemed nice. That's what made him acting so damn weird even worse. He definitely felt like a tool, and he was glad Dean wasn't here to see his awkward display. It didn't help that Rogue was cute.
While the girls talked, Sam decided to pretend he was invisible. It wasn't an achievable feat when you were six friggin' six, but Sam tried, keeping his eyes wandering and alert for any unexpected visitors. Sam hardly noticed when Rogue worked off her gloves and dipped her fingers into the detergent, because he was too busy tensing as he realized that the last time he made an unexpected trip to help another survivor that called for help...? God, it wasn't that far from here..
Oh. Good. She passed the test. That was their cue for them to get the Hell out of dodge, and back behind prison walls before an inevitable encounter took place. Sam swallowed thickly, and flashed another small smile at Rogue before he ducked back into the driver's seat of the truck. Molly could handle the rest of the talking, he could handle the driving.
