"Somebody call the fire department!" David yelled as people ran to find water to put out the flames. Buckets were filled and thrown at the car to try and contain the flames. Finally sirens were heard as a fire truck arrived at the scene. Within minutes hoses were connected to hydrants and the fire was put out.

Once the fire was extinguished Emma and David began asking people what they had seen happen. "I told you. I was walking to the party and I saw the car on fire. That's all!" Leroy explained.

"Alright, no one's blaming you or anything, I'm just taking a statement," David told him.

Just then Emma noticed a familiar figure walking from the crowd. "Hook?" She weaved her way past people to see it was indeed her pirate ex-boyfriend. "Hey, hold on a second."

"What is it Swan," he answered impatiently. "I'm pretty sure when a relationship is ended you stay away from one another."

"I just wanted to know if you saw anything regarding the fire."

"Fraid not. I just got here."

Emma frowned, sensing he wasn't being truthful. Her frown deepened as she picked up the scent of gasoline wafting from his clothes. "Why do you smell like gas?"

Killian silently cursed himself for having accidently splashing the gasoline on himself. "If you must know the Jolly Rodger has some rotted wood planks, so I took care of it with a controlled burn."

"And that's why your hand has soot on it too?" Emma said in a way that showed she didn't believe his story.

"Emma!"

Emma glanced over as David came over. And in that second she was distracted Hook took off like a bat out of hell. "Hey, get back here!" she yelled as the two of them chased after the pirate. She took on a burst of speed as she tackled Killian to the ground.

"Get off me! I'm innocent!"

"Innocent people don't generally run," Emma explained as she and David pulled him off the ground. "You're coming with us to the station."

"Why?"

"Because I think you were involved in burning the patrol car."

"Where the hell is it?" Regina yelled as she continued tearing her vault apart. She was methodical when it came to keeping the place organized. But now she couldn't find the one book she needed. If she had to guess, it wasn't where it should be because Emma probably moved it during one of their magic lessons.

Finally Regina located the book, entitled Natural Phenomenons and the Properties They Hold. She opened to the chapter on Blue Moons and skimmed until she found what she was looking for.

"While double month moons are powerful conduits for spell casting, they are particularly powerful when they occur during the month of October, on the night of All Hallows Eve," she read out loud. "When the second full moon falls on that day, the veil between our world and the spirit world is at its most fragile, and those who were powerful practitioners of magic in life can temporarily cross back over to the world of the living during that special night. While they can return as corporeal beings instead of intangible ghosts, their power is directly connected to the full moon, and they will return to the spirit world once the sun rises on the first day of the preceding month. However, if the returned magic practitioner died an unnatural death at the hand of another, they can remain permanently in the world of the living if they take the life of the one who shorted their life."

Regina put the book down, fear forming as she took in the words she just read. While she had no definite proof, she had a feeling a certain powerful magical practitioner who had died because of someone in Storybrooke had found a way to cross over into this world. And if that was the case, Regina had to warn Mary Margaret, David and Emma, for this would mean one of their lives were definitely in danger tonight.

Just then a burst of flame appeared in the air, following by a scroll falling in front of her feet. Regina picked up the scroll and unrolled it, reading its contents to herself.

Dearest Daughter,

Your presence is requested tonight for a family reunion. Come to the town hall basement right away, where we will right the wrongs that were committed. Don't keep me waiting.

Regina took a deep breath, uncertainty flowing through her. While the note had no signature, it was very obvious it was sent from Cora. And if Regina had to guess the 'right the wrongs that were committed' were killing Snow for casting the curse that killed Cora.

Regina stood alone in her vault, torn at what to do. Despite their shared history she and Snow, while not exactly friends, had become allies within the last couple of years. And she knew Snow's death would be devastating to Emma and Henry (not to mention David.) But Cora was still her mother, and Regina couldn't deny that in spite of everything, a part of her wanted to see her mother and help her not return to the world of the dead.

Honestly not sure on what she was going to do, Regina prepared to poof herself to town hall. But then an idea came to her. She pulled open a drawer and took out a set of shackles that would render the wearer unable to practice magic. She wasn't sure what was going to happen with her mother, but she wanted to be prepared for anything. She placed them in a nearby satchel before poofing from her vault in the blink of an eye.

"Is this really necessary," Killian asked from the back of the other, non-burned cruiser. "I told you, I'm innocent."

"We'll see about that once we get to the station," Emma told him. She then looked over a David, catching the worried look on his face. "Everything okay?"

"Snow's not answering her cell phone," David replied. In all the excitement with the fire and apprehending Killian he hadn't even thought about her until they had started driving to the sheriff's station. Now his guilt was turning to worry as all he got was her voice mail.

"I'm sure she's fine," Emma said, though she couldn't help being a bit worried herself. "She can take care of herself."

"Not against who she's with," Killian said to himself, unaware that Emma caught what he had just said.

David looked over as Emma pulled the cruiser over and got out. "Emma?" He got out of the car too as Emma opened the back door and pulled Killian out. "What are you doing?"

"What do you know?" she asked the pirate.

"I don't know anything."

"Is something happening to my mother?" she asked clear as day. "Is that why you burned the other cruiser?"

"I have no idea what you're talking about."

"Why does everyone here forget that I know when they're lying?" she said with a humorless laugh as she balled her hand into a fist and swung at Hook.

"Emma stop!" David yelled as he caught her arm. "You can't hit him."

"You're right," she said as inspiration came over her. "I have a better idea." Before they grasped her plan Emma grabbed Killian's hook and pulled it off him.

"What the hell Emma!" he yelled.

"Tell me what you know right now or I destroy your precious accessory." He made a grab for it but David stepped in front and held him back. Instead Killian looked on in horror as Emma conjured a fireball of red flame. "Little trick Regina taught me. Burns hotter than regular fire, which should be enough to melt your hook. Now tell me what you know or you go around being called Captain Stump."

"Emma," David said warningly. "I don't think-"

"Alright!" Killian yelled as Emma held his hook over the flame. "I'll tell you. Cora has your mother."

"What?" David said as he got in Killian's face. "What are you talking about? Cora's dead."

"I know she is," Killian replied. "But somehow she's back, though she said it's just for tonight."

"The blue moon," Emma replied. "Mary Margaret said it connects the world of the living and the dead tonight. That's why Cora's back. What else?" she demanded as she held the hook closer to the flame in her hand.

"She said the one who killed her has to die so she can remain here past sunrise. She's going to get Regina to kill Snow so they can rule this world as mother and daughter."

At Killian's words David wanted to punch the pirate himself, but fought against the urge. Instead he slammed him against the cruiser. "Where are they? Where did she take my wife?"

"She said she was taking Snow to a room in the town hall basement. That's why I had to distract you two with the fire. That's all I know, okay?"

With that David pulled the back door open and threw Killian in the cruiser with more force than necessary. "Get in there," he said as he slammed the door shut. "Come on, we've got to get back to town hall."

"I'm going myself," Emma announced as she handed David back Killian's hook.

"What?" he said in confusion.

"Take Killian to the station and make sure he doesn't get away. I want to deal with him when this is over."

"Emma, Snow is trapped with Cora and Regina. You're going to need all the help you can get."

"I have my magic. I'm powerful enough to at least stop her. And I won't be alone. Regina will be there. She's not going to hurt Mary Margaret."

David shook his head at Emma's words. He wanted to believe that Regina really had changed. But he also knew how much persuasion Cora had over her daughter. "Emma, I don't think you realize-"

"She's not going to hurt her," Emma stated, while inwardly hoping her belief in Regina wasn't shattered. "Please trust me on this. I promise we'll get Mary Margaret back. But right now you need to get Killian behind bars, because we can't let him get away either."

David reluctantly nodded his head, choosing to trust his daughter's instincts. "If you need me at all call me right away."

"I will." She watched as he got in the car and sped off before concentrating on town hall. But she couldn't seem to poof herself there. She tried again, but felt like her magic was drained or lessened.

It must have been the flame, she thought, realizing it had taken more of her magical energy then she had anticipated to conjure it. She checked to at least make sure she had her gun on her, so she wasn't going to burst in there completely defenseless. Seeing it was still on her Emma ran to town hall as fast as she could.
