They caught up with the van easily enough which made Dean wonder if they weren't even trying. Maybe they wanted to take them to their secret hide out and this Constantine guy. "Think they'll have some kinda crazy bunker with a helicopter?" It was better topic than the dead girl. He'd like nothing better than to stop thinking about her but she kept creeping into his thoughts.

Thankfully Sam didn't go straight back to ask how Dean felt about hitting a kid on the highway. Instead he said, "Maybe. I'm just wondering if this Constantine knows something about the Mark of Cain."

"Really think that's a good idea, Sammy? Last time we showed a souped up Man of Letters about the mark he wanted to add me to his collection."

"It's worth a shot," said Sam simply.

"Yeah. Maybe." How much easier would it all be if Sam could just accept things as they were? The Mark had been around since the beginning. Why would it go away all of a sudden?

"Dean … about that girl…."

Of course he couldn't leave off forever.

"We should probably talk about what happened."

"Probably, but we're not," said Dean, flashing him a grin he didn't feel. "Just how things go. All we can do is move on and try better next time."

"I'm not so sure she's even a demon."

"Well, great, then we really don't need to worry about it."

Sam sighed. "You're not the least bit curious about something that can masquerade about a demon? That would mean the difference between whether hitting her with…."

"Oh look, need petrol," said Dean, swinging the car with a little too much speed into a petrol station by the side of the road. The other side of the road, necessitating a leap across two lanes of low traffic, but still the side of the road. He pulled up and tapped at the petrol reading, which was a quarter full. "Do the honours?" Without waiting for the answer, he hopped out of the Impala and headed straight for the station.

It'd let the jeep get some distance on them but it was worth it to make a point.

Sam didn't follow him, thankfully. Dean wasn't in the mood to hit someone. Or maybe he was. But it'd be better if that wasn't his brother.

Dean went through the sliding doors and started for the food counter as this place had a menu for burgers, chips and pies. As he passed the tables pressed up against the window, he glimpsed someone out of the corner of his eye that made him stop and turn. "Hey demon."

The kid looked up, eyes wide and teeth still clamped into the edge of a burger. Her eyes weren't black anymore and she would've seemed normal but for her calmness. No way would a twelve-or-so-year-old be so calm after what had just happened post-possession. Not to mention there'd be bruises, at least, a few broken ribs. Maybe a broken spine.

He really didn't want to think about that.

She glared at him, took a big deliberate bite of her burger and chewed, still glaring at him with narrowed eyes like he was the bad guy.

"So looks like I found you," he said, swinging down to sit next to her and pressing the angel knife against her hip.

She looked down at it, swallowed and smiled. "Angel knife, cool."

Now that really pissed him off. "Look, demon, we're gonna talk about what happened back there and then I'm going to hand you off to Crowley."

"He'll torture me," she said, taking another bite.

"Like I care."

"Torture Deanna too."

"Whose Deanna?"

"The girl who I'm wearing," she said, again like he was the idiot. For a demon she really did come off as a snotty nosed pre-teen. "Do you really want her suffering in Hell at the hands of Crowley?"

"Maybe you could just let her go," said Dean. "Make a run for it."

"I could."

"Then do it."

She hesitated. "Don't want to." Then she whispered sullenly, "I'm not trying to aggravate him."

Dean frowned and risked a glance out the window to see if Sam was nearly done at the pumps. He needed his brother to sort this out. "Who're you talking to?"

"No one."

"Riiight."

"Look, just let me go and the girl will be returned to her family, safe as houses."

He turned his glare on her, pressed the point of the knife into her hip just slightly and was glad to see her flinch a little. "Bullshit."

"I give you my word, could even do you a deal about it."

"You're no crossroads demon."

"I'm branching out," she quipped.

"You're really not taking this seriously."

Sam was done at the pumps and heading into the station. Soon he'd have back up.

"Hey, you don't want to hand me over to Crowley," said the girl. "Lemme tell you, you do not want to be the one handing this girl over to demons. That will not go well for you because my family will get so angry they'll hunt you down like a dog." She folded her arms across her chest, all attitude. "They're really loyal. They'll do anything for each other."

"Oh really?" asked Dean, frowning over at the sliding doors which just weren't opening for Sam. "Didn't know demons have families."

"They don't. Deanna does." She looked so damn proud. It was positively human. "And her families a real kicker. You'll want to run and hide when you find out."

"Uh huh. So you're possessing some famous hunter's kid and you think that'll make me let you go?" He shook his head, snorted. "So whose this hunter?"

She grabbed at her head. "Ow!"

Dean straightened in his chair. "Don't you hurt her!" What could he do? Jab her with the knife? Hurt the demon and the girl as well?

When the girl looked at him again it was with pitch black eyes. "I have a counter offer for you. Take us to a hospital with a highly skilled team of surgeons on standby. Once in the emergency ward, I will release her. You will not need Crowley for that."

Sam was knocking on the glass. The sliding doors were still not working. One of the attendants went over to try and help.

"Are we in agreement?" The demon's deal really did seem like the better option.

"Fine," said Dean with a scowl. "But this isn't over."

The demon nodded and the sliding doors opened, allowing Sam inside.
