Sarah called in the new information to Casey as they returned to the interrogation room. Apparently Chuck had just had a flash, and they were surrounding a suspect as they spoke. Hopefully they had the right one this time.

In the underground facility, the captive was waking. She had wild eyes that were nearly as frightening as Chuck's had been when they had turned black. The gag was still in place, preventing any spell-casting. Sarah was thankful for that, although it did present a difficulty in interrogation. How do you get answers from someone without allowing them to speak?

The first idea was simply to have her write her answers down. That was a bust – she refused to touch the pen. In the end it took Morgan's loud expression of disappointment in Sam for not knowing the counter spells to give them the idea of connecting the wireless and looking up witchcraft on the internet. Sam pulled up – the A-Z of defensive witchcraft, for all your counter spell needs. He held it ready at the index.

Morgan stood over her with the tranq gun, just in case.

Sarah removed the gag. The witch began to chant. Sam's shirt caught fire. Apparently, she was not very imaginative. Obviously not the brains of the operation, then. Sam didn't seem to care that his shirt was on fire, calmly ignoring his blistering skin as he pulled up the counter spell and began to chant.

There was a lot of shouting, then, as the witch and Sam tried to drown one another out. Sarah wasn't sure who she was more frightened of – the witch with the crazed eyes who was bringing fire forth from nothing, making it spread from Sam to the furniture and walls, or Sam, huge, menacing, and part monster, screaming in Latin and apparently experiencing no pain from the fire that raged across his back and arms. She would not show her fear though, and calmly helped extinguish Morgan when he caught alight once more.

Suddenly, there was a roar, a rush of wind, and the fire flashed blue for an instant. And then it was out. Sam shrunk once more into a normal human with blistered arms and a slightly hurt expression, like someone had just eaten the cookie he was saving. The witch looked exhausted, drained, defeated.

"Fine," she said, "I'll answer your questions."

Across the road, it all happened very fast. The man Chuck flashed on was one Theodore Green. He was inconspicuous, with no identifying features. Average height, average weight, forgettable face. MIT dropout, with previous arrests on weapons charges and suspicion of conspiracy and terrorist activities, but no convictions.

When he realised he was surrounded, Theodore lashed out towards Chuck. Chuck had a kung-fu flash, and felled him with one blow to the neck. Chuck felt a bit better about having been possessed and nearly killing Sarah, then. Not much, though. But he had got the bad guy almost single-handedly. Castiel hadn't even had to use his mighty angelic power to apprehend him. He and Dean both looked a little disappointed at this, but Chuck didn't let it bother him.

Casey grunted approval as they searched the suspect for the game. In his ear, Sarah was confirming they had the right suspect this time. The witch over at Castle had completely rolled over and was talking like Chuck the Prophet's girlfriend Becky (who hadn't stopped talking about the Winchesters the entire time she'd been awake) on truth serum. In the background, Chuck could hear Morgan talking excitedly about spells and fire, and he was suddenly very glad he had not been involved in that particular interrogation.

They walked the handcuffed Theodore across the road to headquarters, Chuck and Casey on either side, Dean and Castiel bringing up the rear.

"Dude, that was awesome! Where did you learn that?" Dean exclaimed to Chuck.

Chuck grinned. Dean from Supernatural had just called him awesome! Wait till he told Morgan. Casey snorted derisively.

Castle was a mess. Morgan hadn't been joking about the fire. Great blackened scorch marks ran along the walls, and both Morgan and Sam were in burnt rags, while a lightly singed Sarah applied salve to their red, blistered skin.

"What did you do, Sammy? Sorry, I should have warned you not to let him near the oven."

"I'm no worse than you, Dean. How many times did you set fire to the kitchen growing up? Four?"

"One of those was totally not my fault. And you managed to cause three even though you cooked way less than me."

"Um... guys? What happened?" Chuck interrupted. It looked like the Winchesters could go on for hours when they got going. Plus, he really didn't want Morgan bringing up that time they had tried to making Thanksgiving dinner.

"There was a magic fight. The witch set us on fire, and Sam put us out using a spell from the internet. It was awesome!" Morgan told him. The Winchesters ignored him and kept arguing.

Chuck looked at Sarah, who looked up from her first aid and smiled at him. Chuck's insides shrivelled. What do you say to your girlfriend when you've just tried to kill her? She was pretending everything was ok, but he could tell from her eyes that it wasn't.

He smiled back. "Who's up for dinner with Ellie and Awesome?"

The Winchesters and Castiel politely declined. Sarah looked slightly relieved, and Morgan looked extremely disappointed. Sarah came, though, and Casey, when he had locked up the prisoners for later collection, and shaken hands with the Winchesters, handing Sam a card. By the time they had finished the paperwork and emerged from the underground facility, the Winchesters were gone. It was like they had never been there. Except for the burnt shell of a CIA base, the bodies in the bunker, and the dozen confused men locked in the home entertainment section.

They signed into a motel just before midnight. Dean teased Sam endlessly for his CIA skills, and Sam looked smugly at the card Casey had given him. In case he ever needed a job, the NSA was always in need of field agents with skills like his. Castiel watched Dean fuss over Sam's burns for a few moments, then leaned back against the headboard as Dean pulled a DVD from his bag. Dean inserted the DVD into the laptop, and crawled up on the bed next to Cas as the opening music played.

Castiel sighed with contentment. Tomorrow he would seek revelation. Tonight, he would watch Star Wars with Dean.

A/N: That's it, folks! Thanks for reading, and for all the reviews. Congratulations on making it all the way to the end.
