The Fishing Joke

Episode 51 of Nightwing & Batgirl.
== Plot ==
In the Batcave, at the lavatory, Bruce Wayne saw a mysterious bath tub. He asked Alfred if he's installed a bath tub there before, and Alfred took a look. Alfred said he only saw the tub just now as well. Bruce felt something suspicious in it. Maybe some magical or supernatural presence within the Batcave. But, Alfred detected none on the Batcomputer. The tub seemed safe. Bruce just thought that he must have installed this inside the lavatory and they just forgot when. Bruce now took off his clothes, sat at the tub, and turned on the shower. Meanwhile, Talia al Ghul was still sleeping on the master bedroom. Back at the tub, it seemed everything was going fine, until Bruce felt he was sinking and being pulled down by a downward current. He called Alfred who hurriedly came to the lavatory but upon reaching there, Alfred was already late. He was flushed down the tub. The last thing he heard was his yell. Alfred immediately woke up Talia to tell her what happened. Talia doubted it was true at first, but was later convinced that Alfred actually saw what he saw. Batman on the other hand, was transported in the middle of Atlantis. Atlantean women were shocked at the sight of the naked Bruce Wayne with only an underwear on. Due to the scandal he caused, the Atlantean guards brought him to the palace. He kept telling the guards he's Batman but they weren't convinced. When Batman was brought to the palace, he was confronted by Aquaman and Mera. 
"Bruce?", Mera said, recognizing him. 
"Outrageous! It's my old friend Batman! What's the meaning of this scandalous act?", Aquaman asked. 
"I know, it wouldn't make sense but", Batman explained himself. 
Meanwhile at the Batcave, Nightwing and Batgirl came after being called on by Alfred. He explained to them what happened, and the two could not believe it. Back at Atlantis, after hearing Batman's explanation, Aquaman told him to get dressed. He was given by the royal servants an Atlantean clothing with a Bat symbol. 
"Wow. You didn't have to, but thanks for the customized Atlantean suit", Batman thanked Aquaman and his wife. 
The three continued the conversation at the king and queen's private room. Suddenly, there was an attack heard outside the palace. Buildings were crumbling. It caught Batman, Aquaman, and Mera's attention. They went outside to take a look and they were surprised at the sight of the Deep Six, a group of Aquaman's foes. Meanwhile, in the Batcave, there was a breaking news displayed by the Batcomputer where Joker and Harley Quinn are seen polluting the Atlantic Ocean with laughing gas. Nightwing and Batgirl were ready to spring into action but at that moment, Aquaman sent them a call as well, that Atlantis is under attack again. The two are faced with a dilemma. Which would they choose to head to? Good thing Talia al Ghul decided to take part in the action. She told the two that she will head towards Harley and Joker's ship, while Nightwing and Batgirl head below (Atlantis). They all agreed. Now, Nightwing and Batgirl headed to the R-Plane and flew away, while Alfred gave Talia access to the Batplane, and gave her the coordinates to get to Atlantic Ocean. The scene moves to Talia reaching and landing the Batplane onto Joker and Harley's large ship. Joker told his henchmen to attack Talia. Talia took them down easily with her gun and swords. Meanwhile, Nightwing and Batgirl reached Atlantis, and battled the Deep Six along with Batman, Aquaman, Mera, Aqualad, and Aquagirl. Aquagirl and Batgirl took on Gole, Aqualad took on Jaffar, Nightwing on Pyron, Mera on Shaligo, Batman on Trok, and Aquaman took on Slig. The Atlantean army handled their soldier minions. Batman asked Nightwing and Batgirl about Talia, and they told him she went after to stop Joker and Harley's scheme of creating laughing fish in Atlantic Ocean. Batman immediately contacted Talia, who was now currently battling Joker, Harley, and a school of laughing fish. She shot the laughing fish dead. She was also beating up Joker and Harley and holding her own. Batman asked if she's alright and she said she's perfectly fine. Batman told her to go contact him if she needed back up. Talia agreed. However, she was later knocked down by Harley, and Batman heard her groan as she still hadn't dropped the call yet. 
"Talia! Are you okay? Answer me!", Batman yelled. 
Joker sprayed laughing gas on Talia, and all Batman heard was Talia's lunatic laugh, the effect of the Joker's laugh gas. Batman was beaten by Trok. Then, he fought back and knocked him away. Batman called Nightwing and Batgirl to come with him to rescue Talia. Aquaman, Mera, and company told Batman they could leave the Deep Six to them, but the villains would not let them escape that easily. They chased them outside Atlantis. Aquaman, Mera, Aqualad, and Aquagirl followed, and they all rode the R-Marine. The Deep Six shot laser cannons at them, which the R-Plane evaded. Then, after emerging from the waters, they climbed aboard the ship. The Deep Six and the heroes were shocked to see laughing fish jump up and down from the waters. 
"What did you do? What happened to Talia.", Batman asked Joker and Harley. 
"We used laugh gas infected worms as fish bait. Then, we went fishing and put them back to the ocean just for fun. About Talia, we kept her in the storage room", Joker said. 
"That's the most stupid thing you could ever do. Do you know how much destruction it could cause to habitats of sea creatures?", Aquaman yelled at them. 
"How dare you do that to Talia!", Batman said, enraged as well. 
"Yes, and knowing that makes it even more fun", Joker said, enraging Aquaman even more. 
Then, the Deep Six went aboard the ship as well, and went back to attacking the heroes. 
"Hey! Who the hell are you guys? Stay out of this! Mind your own business!", Harley Quinn told them. Harley and Joker helped the heroes battle the Deep Six. Harley hit them hard with her mallet. 
"You know what they say! The enemy of enemy is my friend", Joker said, laughing manically while hitting the six with his gimmick gadgets. 
While everyone were busy, Batman used this as time to search for Talia in one the rooms inside the ship. But searching where Talia was was difficult for him as he faced Joker's henchmen along the way. But he defeated all the henchmen and soon found Talia in one of the rooms. He was shocked to see Talia keeping a rictus grin despite unconscious. He threw a chloroform smoke pill to see if it will help remove Talia's rictus grin and wear off the effect of the laugh gas, and it did. However, Talia was still unconscious. He proceeded to carry her back to the ship deck. When he returned, he saw Joker and Harley Quinn pushing the Deep Six down the ocean. 
"And now to deal with... You, Batman and company!", Joker told the heroes. 
Batman put Talia down for a while, then as Joker was about to spray laughing gas at the others, he knocked the spray from Joker's hands from behind. Aquaman knocked him out with a punch. Batgirl had a little more fight with Harley Quinn before she finally knocks her out. Now, Batman tied them with the Batrope. Talia regained consciousness and ask what happened. Then, when she remembered, she slapped Harley and Joker hard. Talia thanked the heroes, and told them she and Batman will take care of Joker and Harley, as they rode the Batplane, bringing the two villains with them, still tied together. 
"What do you plan to do with the laughing fish, Aquaman?", Batman asked him. 
"We got this. We'll bring them to Atlantean labs to see if these can still be saved. The only problem is the laugh gas spills. We don't know if we'll be able to treat this", Aquaman answered, as he and Mera used giant nets from the ship to catch all the laughing fish. 
"Good luck with that. Farewell for now", Talia told the other heroes, as she clung onto Batman and they shared a kiss, while sitting on the Batplane. 
"Excuse me... but ew", Harley said, as she and Joker saw it. They were sitting behind Batman and Talia on the plane. 
"Shut up", Talia told her, as she sprayed pepper spray on the two, causing them to lose consciousness. 
"So, what do you plan to do, Nightwing and Batgirl?", Batman asked. 
"Aquaman and company, we're going now as well.", Batgirl said, as she and Nightwing bid the Aquaman family farewell. 
Now, Nightwing and Batgirl entered the R-Marine, and turned it back into the R-Plane while Batman closed the door of the Batplane. Batman and Nightwing now flew their planes. The episode ends with the Aquaman family diving down the ocean, bringing the laughing fish, on safety nets, with them, then swimming towards Atlantis.
