After agreeing to help Lasko's shipmates, Caelan walked over to Jack and asked, "Tell me, what binds you here Jack? I want you to find peace."

Jack smiled lightly, "Thank you pirate. Before I joined up with Ratbeard, I worked for Captain Avery. But I held a shameful secret. The Cutthroats were paying me to spy on him. They're planning something big, and Avery may be in trouble. I can't move on until I know Avery is safe. I was going to meet the sharks down in that tunnel after dinner. Look how that turned out."

Caelan nodded, and went through the tunnel, followed by his shipmates. When they got to the other side of the tunnel, they saw a Cutthroat waiting for them, "You're not Jack! Boys, take 'em down! They've already seen too much!"

A crew of sharks attacked Caelan and his crew, but the sharks were far outnumbered, and outmatched. When the last shark was on the ground, Caelan growled at him, "Alright chum-breath, what's this plan of yours?"

As Caelan wound up a punch with his left arm, the shark begged, "All right, I'll talk, I'll talk! The plan is to do Avery in. With him gone, Skull Island will fall."

John growled, "We've got to tell Avery about this!"

"Aye" Caelan and his crew hurried back to their ship and set sail back to Skull Island.

When the pirates returned to Avery's office and explained the situation, Avery didn't seem worried, "Those bully cowards don't have the gumption or the brains to run Skull Island. Then again, after that business with Finn, I can't be too careful. Go over to Mordekai, he's the head of security on the island. If he thinks this is something to worry about, he'll be able to help."

When the crew went and explained the situation to Mordekai, he sighed, "I knew Jack was up to something, but I never expected this. The Cutthroats have been muscling in on Skull Island. But still, we must make sure Avery stays safe. Next to Swashbuckler's Hall, there's a grate, it leads to Avery's secret escape dock. That's where I would go if I were trying to sneak in." When the crew started to leave, Mordekai called out, "Wait. I know you five have gotten stronger, but your skills still need polishing. John, you stay here with me, and the rest of you should go to your own trainers. There's no such thing as practicing too much."

Caelan nodded, "Thanks, that's a good idea. All right guys, train with your trainer, if the Sharks are making a move against Avery, we're going to need to be a lot stronger than we already are."

Sarah put her hand on Caelan's shoulder and asked him, "Captain, if you don't mind, can my crew, well... your new shipmates. Well, you get what I mean. Do you mind if we train with you?"

Caelan smiled at Sarah, "Of course, we're a crew now, together through thick and thin. Why don't you come with me to train at Swashbuckler's Hall?"

As the group split up, Caelan went to Swashbuckler's Hall to train with Morgan and Sarah. Sarah smiled at Morgan, "It's been a while since we've sparred Morgan, you don't mind do you?"

Morgan smiled, "Of course I don't! Especially if you're with my dashing prodigy." The three swashbucklers started to clash swords, Caelan gaining the edge against both Morgan and Sarah.

As they took a break from training, Sarah asked, "Captain, I hope you don't mind me asking, but how did you lose your hand?"

Caelan sighed, "That happened a long time ago. Me and the others were running from the Armada, when we tried hiding in a lake, a crocigator bit my hand off."

Sarah winced from the explanation, "Sorry if I was prying. I was just curious."

Caelan nodded, "It's fine. Come on, let's get back to the others and go down that escape tunnel."

When the crew met back up, they had gone down the tunnel to meet the guards there. When they explained the situation, a rat called Sergent Seeger said, "That's terrible! Terrible that is that somebody's clearly been talking too much. Get 'em!"

Caelan and his crew quickly knocked past Seeger's men, seeing a shark who talked ridiculously, as if it was his first day being a pirate.

John growled when the shark got away, but seemed content enough that they'd caught Seeger before he could escape. "All right, traitor, start talking before we bring to to Mordekai. I don't think he'll be happy that you've turned traitor, and his teeth are a lot sharper than mine, and he's much more skilled than I am with a blade."

Seeger cringed at the thought of being brought back to Mordekai, "All right! The sharks, they said they wouldn't eat us if we helped. I met a Thresher in Devilfish Hollow, he gave me the details. They've got some new master, aims to take back the Skyway. They're building a fire ship out in the skies near Jonah Town."

Caelan's eyes widened when Seeger said the sharks were building a fire ship. "Alright Seeger, we'll let you go for now. But if you warn the sharks, we'll be giving you a proper burial at skies."

The crew hurried back to Mordekai, who was shocked when they told him about the fire ship, "This plan, it is too subtle for the sharks. Somebody is helping them."

Susan nodded, explaining, "While I was training with Madame Vadima, she helped me see past the magic that I believe if being used by this new master. We couldn't see him with Vadima's crystal ball, but he isn't something normal from Skull Island. I already cast a charm so the magic will not block our sight of them."

Mordekai nodded, "Good, good. Go to this fire ship of theirs, and destroy it before it can set course for the docks. If the docks are destroyed, there will be panic, and no means to escape."

The crew nodded and headed back to their ship. As they came into view of the fire ship, they landed at the dock it was tied to and jumped onto the ship. A strange creature, looking like a shrimp looked at them, "Heh, seems like those meddling cretins have arrived."

Caelan chuckled, "So, the sharks are led by a shrimp."

The creature growled, "The proper term is Prawn. Your vision does you credit, but it's too late. The ship is ready to sail. Soon-" suddenly, a creaking sound could be heard, and the prawn looked over to the mast of the ship, seeing it was falling, "Oh shit..."

As the mast fell across the hull of the ship, John yelled, "Take that ya bloody appetizer!"

Caelan laughed heartily and walked up to the battered prawn, "So, you going to talk?"

The prawn pulled himself out of the rubble above him and said, "Your persistence is incredible. I surrender. Take this key, it unlocks the fort behind the top of the place you call "Skull Mountain." By all means, go there. You will find nothing but your doom."

As they left the fire ship, Caelan looked over at John and Barnabus, who were laughing about what John had done and growled, "Which one of you came up with that plan to begin with? You could have blown the ship to bits, with us on it!"

John cringed and sighed, "I'm sorry cap'n, I should have thought about it before I went through with the plan. It was my idea, Barnabus just supported the idea, he didn't have anything to do with it."

Caelan sighed, "We'll talk about this later, for now we have to stop these prawn things from overtaking the island." The crew sailed back to Skull Island and went to the fort, right where the prawn from the fire ship said it was. Once the lock was opened, Caelan yelled, "Charge!" charging forward, followed by his crew.

After the crew fought their way into the temple, a larger prawn growled at them, "Inconceivable! How can you thick headed cretins oppose us with such success!?"

Caelan drew his sword and said, "Those who fight for nothing but themselves will never know what it means to care for others. As long as I stand, I will not let people like you win!"

When the fight was over, the prawns were defeated and Bonnie Anne cheered, "Let's go tell Mordekai the plot's been ruined."

Before they left the temple, a voice called out, "Wait!"

Caelan turned to see the voice and saw another Prawn and sighed, "Another one? Don't you guys know when to give up?"

The prawn shook his head and explained, "I mean no harm. I... this isn't easy, but I've developed a sort of respect for you. With the Prawn society in tatters, we will go separate ways. But my respect for you draws me to your side. Please, allow me to join your crew."

Caelan was surprised that the prawn wanted to join his crew, and smiled, "Of course. A person willing to swallow their pride and admit their mistakes is fine by me. What's your name?"

The prawn smiled, although it didn't really show, "My name is Sarigoz. Thank you for your kindness... captain."

Caelan's crew went to tell Mordekai, who was wary of the prawn, but said, "I believe that Jack's heart is in the right place trying to protect Avery and the residents of Skull Island. Tell him he has made up for his mistakes."

Once the crew got back to Traitor's Cave, Caelan told Jack, "Everything's been set right Jack. Mordekai has forgiven you, and Avery is safe."

Jack's ghost smiled, "Thank you pirate. We might have been enemies in life, but you've set me free. Tell Lasko we're square."

When Lasko saw that Jack had moved on, he told Caelan, "Thank ye pirate, but there's still work to be done before I put you on Ratbeard's trail."
