Tasam1075 requested: Serial Killer - something deadly is happening to the marine life and Gordon's got to protect his 'world'

A/N: This was hard to write. I don't like making Gordon evil! XD

Warnings for death and minor mentions of marine life death

The first time wasn't even intentional.

He'd arrived on the scene, ready to save the crew in the broken down submarine. However, when he saw the oil-stained water, he was so stunned he couldn't move.

He thought that they were past using toxic fuels that damaged the environment, but it seemed that whoever built this sub didn't seem to care about that. Now a leak was causing the oil to seep into the water, turning the ocean around Gordon so murky and black he could barely see past a few metres ahead of him.

He didn't realise how long he had stopped to just stare in horror until John's voice was suddenly in his ear.

"Gordon."

"Yeah, I'm going as fast as I can," Gordon lied, like he hadn't just been sitting there, and grabbed Four's controls.

"No, there's no need."

Gordon paused and frowned, not understanding what John was saying.

"There's no more lifesigns in the sub."

"Oh."

John's voice sounded sullen yet comforting, like he was trying to reassure Gordon that it wasn't his fault. However, Gordon didn't feel regretful that he didn't make it there in time. Instead, he was glad that those people had paid for what they had done to the ocean.

For a moment he was surprised at how he felt. A whole crew had just died. They probably had friends and family who would miss them immensely. But then he remembered what they had done, and how so many sea creatures would also die due to their idiocy. Gordon felt bad for those who would mourn the crew, but he wouldn't be one of them. They got what was coming to them.

The tragedy of what happened to that submarine was something Gordon quickly got over. Rescues continued on as normal, and Gordon tried to save as many people as he could, just like before.

But then there was another incident. A seismic vessel was sinking and Gordon was sent out to go and rescue it.

He went out with great reluctance. He knew what these kinds of ships did. They willingly killed marine life with their seismic blasts just to make profit from whatever oil was left offshore, and he didn't think that anyone who did that deserved rescuing.

These thoughts circled though his head as he headed towards the scene. If it was down to him, he would have left them to drown, but his brothers didn't see the world the way he did, and they wouldn't understand that these people deserved it. However, as he left Thunderbird Two and started to make his way down towards the ship that was sinking beneath the surface, he realised that down here, he was on his own. He could do what he wanted.

Of course, he couldn't make it obvious, or his brothers would know he didn't save these people on purpose. So, he acted like he was intending to save this crew. He got his equipment together, but he took slightly too long to get ready. He dived out of his ship, but swam a little slower than normal. He cut his way into the hull, taking just a few extra seconds than he should.

All of it added up, and by the time he made it to the ship, it had taken on too much water and was now completely beneath the water. Gordon searched the ship for survivors, but there was water in every nook and cranny, and the only bodies he found were those that floated lifeless in the water.

"Any survivors, Thunderbird Four?" Virgil asked as Gordon searched the last section of the ship.

"Negative, Thunderbird Two." Gordon tried to add sadness to his voice despite the fact that he was smiling. "Tagging the bodies for retrieval."

"FAB."

Gordon knew that as soon as he got back to Two, a hug from Virgil would be waiting for him. Gordon would act like he needed it. He would squeeze his brother tight and linger for a few seconds, maybe even give him a watery smile, all to hide the glee he felt at another successful mission.

By the time the call came in about a whaler that had a tear in its hull, Gordon already knew what he needed to do. He spent the journey putting together his plan of how he could pull this off. This would all be so much easier if he didn't have prying eyes and ears nosing in on everything he was doing.

"Going down to repair the hull now," Gordon informed his brothers as he moved out of the module and entered the water. However, before he went under the surface, he caught sight of what was laying on the deck of the ship, and Gordon felt his anger increase tenfold. If there was any lingering doubt in Gordon's decisions, it was all gone now.

The tear in the bulkhead of the ship wasn't too big and it would be an easy repair. How unfortunate.

Gordon grasped the controls of Four's arms and, rather than turning on the foam that would fill up the gap, he moved the arms to grab hold of each side of the tear. He could feel the strain as he pulled the tear even further open, and water rushed in even quicker as the ship was nearly split in half.

He quickly flicked the switch on to start the foam before anyone had suspicions.

"Uh, guys. This tear is way too big, and it's just getting bigger. The foam isn't doing anything."

It was true. The gap was now too big, and would take too much foam and time to seal up. Even then, with how much water was rushing in, he would be too late to save the crew.

"FAB, Gordon. Forget fixing the ship, and just concentrate on saving the crew," Scott commanded.

"FAB."

Gordon manoeuvred Thunderbird Four towards the surface, a bitter taste in his mouth. The ship was sinking, but the crew was currently fine. He didn't think he could wait for them to just drown. His brothers would definitely notice him just not doing anything.

The crew was currently on the deck, which was now much more in the water than it had been when Gordon arrived. The crew of three were clinging onto the bow of the ship, which was the only part still above water. They waved furiously when they saw Gordon appear, and Gordon had to sit there for a moment and work out what he was going to do.

"Gordon?" Scott prompted after he noticed his hesitation.

"I'm working out how to get them off the ship safely," Gordon lied.

He couldn't see how he was going to do this, so he debated just letting these men go. He had put the ship out of commission at least, it was just a shame that these awful people would be able to live another day.

But then a miracle happened. Something jolted the ship, which was likely the ship finally tearing completely in half, and the bow slammed back down into the sea. The men went flying, a couple of them slamming into the ship on the way down and being knocked unconscious.

Gordon tried to seem alarmed as he dove back under the water to retrieve the men. It took him a moment to find their floating bodies, and he was slower than usual as he grabbed them and took them back to Four.

All of them were unconscious by the time Gordon laid them down on the floor.

"Starting CPR," he said into his comms as he pressed lightly against the first man's chest.

He didn't put in much effort, but this had to seem realistic and like he'd tried to save these men. He felt the ribs start to crack beneath his hands, and he panted into his comm to show that he was trying oh so hard.

"Gordon," he heard uttered through his comm when he was onto the third man.

He took that as his cue to stop, not even hesitating to sit up and remove his fists from the man.

"But-" He pretended to protest.

"You tried your best," Scott reassured, but Gordon didn't need it. He knew he had done exactly what he needed to do.

From that point on, it just got easier. He only ever did it to those who deserved it, to the kind of people who harmed the ocean or marine life without a second thought. It was all justified, and he didn't feel guilty about it. Not at all.

So many creatures were saved because of him. All the bad people, the ships leaking toxic chemicals into the water, the oil rigs, they were claimed by the ocean now, left to be torn up by her deadly waves. And it was Gordon who delivered them to her.

He had been picked by the ocean. He'd known that ever since he was little, and so it was his duty to protect it.

"Hey, Gordon?"

"Hmm?" Gordon stopped in his tracks on his way out to the pool, to turn to Scott who was making his way across the lounge to him.

"That cargo ship you were called out to the other day." Scott seemed thoughtful as he looked down at the tablet he was holding.

"Oh. Yeah." Gordon hung his head as he remembered the 'tragedy' that had occurred that day.

Scott sent him a sympathetic smile, before he turned back to the tablet.

"Sorry for bringing this up. I'm sure you don't want to talk about it. I'm just trying to understand how the hull could have deteriorated so quickly."

"Well, there was a lot of acid in the water. That was probably what did it. It was already in a bad shape before I'd even arrived." That wasn't a complete lie, though Gordon did give it a little boost towards its grave beneath the sea.

"Yeah, I guess you're right." Scott nodded, though he didn't seem happy about it. He never liked admitting defeat. "Sorry again for bringing it up."

"It's fine." Gordon sent him a genuine smile, because in his eyes, it really was all fine. Those sailors met the end they deserved, and that was all there was to it.

Gordon then continued on his way towards the pool, the grin still glistening on his face.

He knew the ocean was pleased at what he was doing. He could feel the thanks she gave him as he felt the water propel him a little quicker each time he headed home. He could feel the warmth of her hug every time he went out for a swim. She had saved him all those years ago, and now he was in her debt.

The ocean was his, and he would do anything it took to keep her safe.
