A/N: The return of the Short Chapter dawns it's ugly head.

I was going to split Chapter 1 in half but I decided against it.

The Italics are placed here because though all Mer folk can hear Humans underwater there is going to be distortion. It will all make sense later on.

Oh. I may not Tag them but I will be mentioning or giving a brief cameo or some Angels / Archangels and other lovable / hateable Characters. Sam, Dean, Castiel and Gabriel are the four Main Characters. Bobby will be a heavy influence but not as involved as the previous floor. Anyways...

Castiel returned at the bank in the early morning however the two Humans, he remembered being named 'Sam' and 'Dean', had not returned. Disheartened was one word for it, possibly disappointed but however those feelings vanished as soon as he spotted the Sam and Dean walking at the far side of the bank again.

Eager to see them up close Castiel dove back underwater and followed their trail, narrowly missing the fishing hooks that sunk into the water, though it would not of killed him it would still hurt if they caught him in a tender place; his tail and gills being high on the protective priority list. He could listen to their chatter with intrigue

"Dean, we really should be at Bobby's"

"He can wait, besides I want to find out what that thing was last night, it could be a case that we've found early"

Castiel had no clue what a 'Case' was in this context. His focus wavered towards the fish that were being drawn to the skewered worm connected to the wire that were in the Human's direction. Shimmying backwards he watched the fish being plucked away once the Humans realised the first had literally taken the bait.

It was Castiel feel nauseous but knowing that Humans regularly fish and require the innocent to feed themselves Castiel couldn't find himself to be angry

"Sam, quit giving me that look. Bobby would drag our asses down if he was that desperate for our help"

"Dean, if you- Wait, was this your plan? Sit and fish until we find what that thing was last night"

The word 'thing' made Castiel's stomach churn, he was not a 'thing' or 'it' or 'freak' he was a Merman. As far as he was aware only few Humans really knew about them, their potential and abilities however those men were alive in the days of pirates and thieves, it was long since then given how modern Humans travel but road compared to sea now in terms of long distance.

His thoughts were interrupted as a chirping noise trilled over his head, followed by a response from Dean

"Bobby, hey"

"Yes"

"I know, I just wanted to check something- Sam, Sam quit it!"

"Bobby listen... I get it. OK. I just think there is a case here. Ask another Hunter, we're not the only ones out there, maybe Garth if he isn't busy"

"So, this is where you've snuck off to" A charming yet annoyingly familiar voice caught Castiel's attention, as did a silvery-grey tail swirling past him

"Balthazar?"

"Castiel, you know Human interaction never ends well for us. You do remember the incident with Hael, don't you?"

"Yes!" Castiel snapped

"Sam, you hear that?"

"Stay down" Balthazar pulled Castiel behind him

"I am not a child!" Castiel was sick of everyone treating him like a baby. He hated himself for how he became emotional during his re-living of Hael's death. Words must have spread, it never takes long.

"Castiel be quiet"

"No"

"I'm sorry, do you want to be dragged on land and sliced into pieces?"

Castiel huffed, remaining quiet "Didn't think so"

"Sam, I swear I heard something. Let's wait this case out a few days"

"Dean we don't have a case, you're just trying to make an excuse to fish instead of hunt"

"We deserve a break now and then"

"A break? Hunters. Move!" Balthazar snagged Castiel's arm, swimming as fast as physically possible.

Castiel had never heard of 'Hunters' before but he came across whispers or rumours that they were a result of Supernatural Beings deaths, there was no way Castiel would open himself up to these people only to be murdered at their regular shaped hands. They were trained, professional killers and Castiel would prefer to stay alive than be at the mercy of their wrath.
