Warnings: Spoilers for season 11! Starting next line!

Inspiration: Season 11, episode 14 "The vessel". Where Lucifer, uh, misses submarine (lol) and plunges into the ocean instead. Also, reference to "Changing Channels."

Summary: Angels ambush Dean and Cas in a warehouse to ask some question. What questions? Doesn't matter. What matters is how Dean gets rid of them, and what happens to Cas when he does.

I wanted this to look... authentic, something that could happen in a general sense. But I needed a good enough reason for Dean to banish angels with the sigil, when I remembered the angels aren't very nice most times.

"Dean! Dean, you okay?"

"Yeah, yeah. I'm good. You?"

"I'm fine, but what happened in that warehouse? I tried to get in, but it's like the doors were sealed tight. Were these angels? Demons wouldn't have left me out like that,"

"Yeah, freaking angels had us ambushed, wanted to ask a few questions. I banished them before it could get ugly." Dean told his brother and looked around in alarm. "Hopefully they got what they came for and won't be back for seconds."

"Well, as long as you're good. I didn't know what the hell was happening, so I—wait, where's, uh...?" Sam drifted, leaving Dean to pick up the question and looked around. Dean swallowed. Sam gave him a bitch-face, understanding.

"You banished him too, didn't you."

Dean had the decency too look abashed. "I had to, okay? We were outnumbered, they started bitching and getting hostile—I didn't plan on sending him away, he just got caught in the blast." he tried to reason. "look, I'm sure he's fine. He recovers fast, usually make it back in ten. Not like it's his first rodeo."

"Next time, a warning would be nice." a deep, grim voice gritted behind them and the two jumped in alert.

"Cas—"

"Save it."

"Look, I'm sorry, but—why are you wet? Is that blood? You hurt? What the hell happened to you? You were gone for like five minutes!" Dean sputtered the moment his eyes laid on the angel. Castiel stood with his shoulder to them in the empty lot by the warehouse, squeezing his trenchcoat like a rag, both him and the coat dripping so wet they were creating a pond on the concrete around his feet. Cas was drenched, not like getting-caught-in-the-rain wet, but fell-into-a-lake-with-clothes-still-on wet.

"I'm fine, Dean." Cas growled in exasperation without sparing a glance, clearly tongue-in-cheek. "Why wouldn't I be?"

"What the hell happened to you, man?" Sam drawled slowly, looking him up and down, freaked out. Castiel wasn't just soaked to the bone, he was a mess; his white dress shirt was tucked halfway out of his pants and completely torn apart, pants ripped and his blue tie was missing a crucial chunk of it's overall structure. He had bloody red stains all over him, which might be fresh, but Cas was generally still dripping water right now, and Sam was certain Castiel's hair would have been standing up wildly if it wasn't so wet and flattened. It seemed like he also lost the black suit jacket along the way. Whatever that... way... might be.

All in all, he didn't seem to have any injuries (but he's an angel; he heals fast), but his clothes looked like scraps of some Zombie Apocalypse movie set.

"Well, I believe Dean used the banishing sigil to banish the angels, not minding collateral damage, which sent me halfway across the planet." Dean fidgeted under Cas's accusing stare.

"Yeah—no, I-I mean, why are you... Soaked, and why are your clothes ripped?" Sam's stuttered, brow creasing in confusion. "You're covered in blood. Where the hell did you land?"

"Earth, not Hell. Thought it might as well have been. The South Pacific Ocean." Cas gritted, tossing Dean another accusing glare. "Specifically, six-thousand and something feet underwater. These sharks weren't very happy when I dropped out of nowhere right in the middle of their territory."

"Ow." They visibly flinched, face twisting in pain.

"Cas, I'm really sorry, buddy." Dean pleaded, trying to keep a sympathetic expression. "I'll give you a heads up next time, 'K? Sorry about that."

Cas tilted his head. "You think this is funny."

"What? No! Not at all!" Dean's poker face could be convincing most times. Other times, he was a horrible lair. "Plunging into Jaws lair? Not funny at all! Right Sammy?"

"N-no, of course not." Sam cleared his throat. "Nothing funny about that." he shook his head.

"I'm sure this seems funny to you two, but I haven't seen this much teeth since Gabriel and his nightmare piranha tank when he—;" he paused offendedly, focusing his glare back on them. Then looked down to his clothes in irritation. "I need to change." he declared and vanished before anyone could stop him. Dean released a breath, dropping his arms to the sides in a hopeless gesture. "Great."

Sam stared at him. "You're a jerk, you know that?"

"Please, like you don't think it's hilarious." Dean glared back. His brows went up in question. "So... Do we wanna know about this, uh, nightmare piranha tank with Gabriel or—"

"God no."

"Thought as much."

*We still don't know what Gabriel did with Cas in Changing Channels, when he trapped Sam and Dean in TV Land. We only see a bruised nose, but let my imagination run wild for a while.
