Dean would let him borrow the Impala again. Sam had a few times since the sexual encounter between Ruby and himself, in fact. What he wouldn't do was be so eager to let him borrow his baby if he knew that Ruby was going to be coming along for the ride. No matter how much memory loss Dean may have suffered from before, one thing would always remain the same: he would never not be scarred upon discovering that Sam and Ruby had done the deed in the one object that meant more than anything else in the world to him. Which also meant that Sam would never not be secretly smug about having given his brother something to get all anxious and panic about - he deserved it, given the amount of times that he had done the same to Sam. Sneaking girls into their motel rooms, shoving all kinds of unwanted imagery into Sam's head from accidental walk-in's and detailed stories from Dean the night after. Yeah, he totally deserved that one. Just the once, at least. "I don't think I need to remind you of anything," Sam laughed, "you're the most devious person I know. Don't act like you wouldn't jump at the chance to take advantage of a situation like that again without me bringing it up." In fact, Sam was pretty sure that Ruby would be the one doing all the reminding.
Another vase assaulted the wall, just when Sam had been sure that the ghost was giving them a breather. No such luck. Sam glared at the direction that the vase had come flying from, then quickly began to lead the way out to the back of the property. The sooner they got out of that house, the better. That didn't meant that the ghost would limit itself to just the house - no, if there was enough property for there to be graveyard nearby, it'd be out there somewhere too, probably - but at least the open space would give the ghost less material to throw at them. It'd have to greet them face-to-face, which meant that Sam could blow it away with a round of salt for a little while. They'd need the uninterrupted time to dig up the bodies anyway.
Yeah, it was going to be a long night. At least Sam had Ruby at his side to help him through it. It was weird to be hunting with her on a case that wasn't demon or apocalypse related, but Sam found that he fell into sync with her quite easily. She knew how the job worked. More importantly, she knew how to work with him. They were going to tackle all this just fine. "It's good that you can, though," Sam commented about the rock salt holding. "You're married to a hunter. Considering how much of that stuff I have laying around the apartment, I'm glad it can't hurt you anymore." It was also good that it didn't bother her, because if any of his old hunting 'buddies' came whistling through town, they'd be expecting the rock salt and holy water to do the trick. Ruby would have a one-up on them. She'd need that.
As the graveyard began to fall into Sam's line of sight, he glanced over at Ruby. She was distressed at the notion that she sounded like a typical housewife. The idea of Ruby, the former apocalypse driven demon, going for the role of housewife was probably the most entertaining image that Sam had jammed into his head in a long while. "Ah, but you're Ruby. The demon, Ruby. There's no such thing as housewife for you. You're too intimidating and evil for that," Sam teased.
