Regina, Arrow, and Canary tried to figure out what to do.
"Felicity," Arrow said, over his radio, "have you located the bomb yet?"
"Negative," Felicity said, back in the Loft, "Tockman's an expert hacker, more than even me. He's probably shielded it from being located."
"That's bad news." Arrow said.
"Not quite," Regina said, "I can find it with my magic."
"How is magic gonna help us find a bomb?" Arrow asked.
"You'd be surprised what magic can do," Regina said, "for instance—"
She poofed Clock King and Deathstroke back in the warehouse with a cloud of purple smoke.
"Tell us where you planted the bomb, now!" Regina commanded the criminals.
"What makes you think we'll talk?" Clock King asked.
"Well, for starters…" Regina said, promptly jabbing her hand into Tockman's chest and pulling out his heart, "unless you want to live to see tomorrow, I'd suggest you start talking."
"Go ahead," Clock King said, "death means little to me."
"And even less of significance to me!" Deathstroke said, coming up behind Regina.
"Regina, watch out!" Arrow shouted, as she swiftly flung Deathstroke across the room, knocking him out cold. The Arrow tied him up with a bolo arrow.
Regina squeezed Tockman's heart as he writhed in pain.
"Where is it?" she demanded, "Talk!"
"Judging by the beats of my heart," Clock King said, "I surmise that I have approximately two minutes and fifty-two seconds before I collapse from cardiac arrest."
"You'll get worse than cardiac arrest when I'm through with you!" Regina said.
"Go ahead," Canary said, "give him his heart back. I've been meaning to crack some skulls."
"Fine," Regina said, inserting his heart, "if my methods didn't work, perhaps yours will have some affect. He's all yours."
The Canary started kicking him, and he was pinned against the wall.
"Where's the bomb, Tockman?" she demanded, "I'm asking nicely."
Clock King smiled,
"Well, if isn't Ta-er al-Asfer," he said, addressing her by her Arabic title, "such a pretty name, by the way."
"How do you know that name?" she asked in shock, "Are you working for them?"
"That is of no concern to you," Clock King said, "what should matter is finding my bomb."
"Right," Canary said, "which brings us back to my still unanswered question. Where is it? Tell me now and I'll make sure what follows is slightly less painful…as I beat out info of what you're doing with the League."
"The League?" Regina asked, "The Justice League?"
"No, the League of Shadows," Canary said, "trust me, I will find out what they're up to."
"Of course, but while you're doing that," Clock King said, "time is winding down. Tick-tock!"
"Oliver, I found the bomb!" Felicity shouted over the intercom. "It's here in Central City. It's on a sub-level. Below the intersection of Kitniss Ave. and Berlanti drive. It's in the subway."
"Just like him to hide it in the train station," Arrow said, "I'm on my way!"
"Don't bother," Regina said, as she poofed the bomb to warehouse in a cloud of purple smoke.
"Now how do we diffuse it?" Regina yelled.
"You need the access code," Clock King said, "this particular time bomb is voice activated, keyed to a specific frequency."
"This code is?" Arrow asked.
"I'm not going to say." Clock King said.
"If you don't, you'll die along with half this city!" Arrow said.
"As I said, death means little to me." Clock King said.
"I'll do it," Regina said, "what's the password?"
"I think I've got it!" Felicity said.
Regina magically shapeshifted into Clock King.
"Tempus fugitus," he/she said.
The bomb shut off.
Regina transformed back into her normal self.
"Now to return your enemies to prison," Regina said, as she engulfed Deathstroke in a cloud of purple smoke, causing him to disappear back to prison. Clock King, however, had managed to escape.
"Well, we got Slade," Arrow said.
"But Tockman won't get far!" Canary said.
"Thanks, Regina!" Arrow said.
"You're quite welcome!"
"Can't you just poof Tockman back like you did last time?" Canary said, "I need answers!"
"I'm sorry, but my teleporting powers only work within close range or if I know exactly where a person is, and I'm afraid Clock King has escaped my reach." Regina said.
"Then I'm going after him!" Canary said.
"Canary!" Arrow shouted, following after her.
She got on her motorbike.
"Canary!" Arrow called, "Sara, please, think about what you're doing. Control your emotions. Don't let how you feel cloud your judgment."
"Sorry, Ollie, but I need answers," Canary said, "and right now, Tockman's the only one who can give them to me!"
"This is Arrow paging Speedy," Arrow said over his two-way radio. "Follow Canary."
"Speedy to Arrow," Roy said, "affirmative. Bird is in sight."
FLASHBACK: The Island.
Oliver and Sara were combing the beach, when they found Anatoli Knyazev washed up on shore, unconscious.
"Knyazev!" Ollie shouted, "Anatoli, are you all right?
Sara pushed gently on his chest.
"Oliver! Sara!" he said with surprise.
"Are you ok?" Ollie asked. "What happened? Where's the girl?"
"The girl!" Knyazev said, "maybe Slade captured her, or she drowned! Slade was going to kill us!"
"He won't try it again," Ollie said.
"Maybe the girl rescued you," Sara said, "Look what I found."
She handed him a piece of wet parchment.
"What is this?" Knyazev questioned.
"I found it clipped to your jacket." Sara said.
He read the letter aloud:
"Dear Mr. Knyazev, Thank you for all the kindness you showed me. I will never forget you. Please tell Oliver and Sara I'm grateful to them, as well. You'll defeat your enemy. Best of luck, Ariel."
"Ariel, huh." Oliver said, "she didn't look like an Ariel."
Meanwhile, on the other side of the island, Slade was in a fury.
"Someone stole a vial of mirakuru from me!" he shouted, "they're going to pay, starting with Oliver Queen!"
Meanwhile, Ariel had journeyed back to the Enchanted Forest.
She used the magic potion to give herself legs and went into Regina's castle.
"Well," the Queen said, "have you brought me something of value, mermaid?"
She handed her the vial of mirakuru formula she had secretly swiped from Slade.
"What is this?" Regina asked, "You may speak."
She magically restored her voice.
"Thank you, your majesty," Ariel said, "I journeyed to another land. This vial contains something to strengthen a person. It's called mirakuru."
"Interesting," Regina said, "Why would it be of any use to me?"
"Well, with it, you could build yourself an army of super-soldiers to do your bidding," Ariel said.
"That would come in handy," Regina said. "Samuel, I have need of you!"
"Yes, your majesty?" the guard named Samuel asked.
"Take off your gloves, and roll up your sleeves," Regina said.
"Yes, your majesty." Samuel said.
"Now let's see if this works," she said, as she inserted the needle containing the solution into his arm.
Suddenly, Samuel started to writhe with pain. He then proceeded to knock over tables and other furniture in a fit of rage.
He crashed through the wall and fell to his apparent doom.
"That was a waste of time!" Regina said, "and you've been too!"
She took away her voice.
"Away with you, mermaid. Swim home! You are banished from this kingdom!" Regina said, "if you come here again, you won't ever leave!"
She left the castle and swam away as a mermaid.
Back in the present, in Starling City…
Roy confronted Canary.
"Sara, stop!" he shouted. "It's a dead end! Clock King's gone!"
"I have to go after him!" Canary protested, "Tockman knew something, and led on he was working with the League of Shadows!"
"We'll find him!" Roy said, "but right now, we've got places to be."
Later, they joined the Arrow, Regina, Diggle, Felicity, and Laurel with Amanda Waller, who had found a way to send Regina back to Storybrooke.
"This portal isn't as sophisticated as the magical ones you use," Waller said, "but it'll do the job. Thank you for helping defeat Deathstroke, though, Ms. Mills."
"Think nothing of it, Mrs. Waller." Regina said, "it was my pleasure."
"I should warn you," Waller said, "due to our primitive knowledge of dimension-hopping technology, you may very well have no memory of what happened to you here upon returning to Storybrooke."
"Even so," Regina said, "I did enjoy my time here. I'll cherish the memories while I have them, and if need be, I know that all curses can eventually be broken."
"See you later, Regina!" Oliver said, "it was a pleasure working with you!"
"The feeling's mutual," Regina said, shaking his hand. "If you don't mind, I'd like to have a moment alone with the Canary."
"Yes?" Canary asked.
"Canary," Regina started to say, as they walked off to the side.
"Please, call me Sara." Sara said.
"Sara," Regina said, "I know you want to find out what Clock King knows about you, but take it from me. You don't want to let your emotions and assumptions get the better of you."
"I know," Sara said, "I'm sick of lectures, alright?"
"I'm just telling you because I know what that's like," Regina said, "another blonde birdlike girl back home did something to me. The Swan. She inadvertently shattered my dreams of happiness. Instead going back to my dark ways that I know only too well, I'm going to try to be the stronger person."
"Do you really mean that?" Sara asked.
"Well, at least I'm going to try." Regina said, with a smile. "I should be going. I'm sure my son has no clue where I am."
"So long, Regina!" Oliver called, as he Roy, Sara, Laurel, Felicity, Diggle, and Waller looked on as Regina stepped into the portal.
