Leading the way, Regina simultaneously side steps into one mirror and out of another. She arrives in her vault with Harry and Ron trailing behind and Robin at the rear. The two newcomers watch patiently as both Robin and Regina are welcomed home with enthusiasm.

"Mom, Regina, Daddy!" The children call out; the two older rushing forward as the littlest one complains sweetly, "Henr-yyyy, Lemme go, Daddy's back!"

Hugging Roland first to give her oldest time to pass his little sister off, Regina breathes a heavy sigh of relief as she catches sight of someone not seen through the mirror. "Oh good, Daddy, you're here."

The elderly king smiles amiably, deliberately keeping his tone light and comfortable. "I've nowhere else to be just now. As a veiled warning, he offers, "I tried to get your sister to come with us…"

As she looks around, Regina touches young Henry's shoulder in appreciation for his care of his younger siblings and kisses her daughter's forehead, briefly opening her arms, offering to take the girl who refuses with the adamant shake of her head; sending short dark curls fluttering the instant before she nestles deeper into her father's arms. "I guess she declined to come." Regina sighs, knowing without asking that there's certainly trouble beyond the safety of these walls.

"That she did. And, quite colorfully too, I might add. Foolish girl. She went off to try to deal with that thing."

Regina stares hard. "Daddy, what do you mean she went off to try to deal with that thing? You don't mean on her own?"

"I'm afraid that is precisely what I mean. Hades brought her down from Olympus. They left Eliana there temporarily because she was playing with some young family members close to her own age and wasn't ready to leave yet. Hades and Zelena went straight to the underworld. As best I could understand what your sister later relayed, Hades is rather furious with his executive officer. Apparently these dementors can only travel realm to realm courtesy of the underworld. However, Hades has agreed to an embargo restricting the travel of dementors. Fiona failed to honor that embargo. It's not quite clear which one of them is using which, but Fiona has aligned herself with someone your sister referred to as an asylum reject; someone she called Bella. Also, Hades apparently possesses some sort of magical box that is quintessentially a trap for the dementor. Zelena helped herself to the box and left her husband to pass judgment on the guilty. Despite my best effort to convince her otherwise, she's out there chasing after that thing, intent on trapping it all by herself."

Dread paralyzes Regina for a single second. The next, she springs into action. She glances at Harry. "We've got to go now! She's going to get herself killed!" Already moving toward the exit that will take them above ground, she motions rapidly toward their visitors. "Daddy, this is Harry Potter and Ronald Weasley from the Rowlingshire realm, home of the dementor. They've come to lend a hand. Gentlemen, this is my father, King Henry of Covarachia."

Henry waves politely, understanding their need to hurry away. "Forgive me for being abrupt gentlemen, but there will be time enough for us to become acquainted later. If you've come to lend a hand, I'm afraid you're each going to need both - and then some. Emma just reported, there may be as many as five of them now."

"I was afraid of that." Regina says with regret as a wide-eyed Norah tells her father. "Too many, Daddy. Too many ugly monsters."

Robin rubs her back affectionately. "Don't be scared. You're okay. My little firefly is safe here, and Mama brought our new friends to help get rid of the ugly monsters. You stay here with Papa and the boys. We're going to go have a little conversation with those ugly brutes."

When she resists, Robin must forcibly hand his daughter over to his father-in-law.

"No Daddy!" Norah wails pitifully; reaching for him with outstretched arms.

"We have to go. People need our help. You'll see me in just a few minutes; I promise. Stay here, mind your grandfather, and hands off! Don't touch any of Mama's magic things."

As Regina waves goodbye from the top of the stairs, Norah folds her arms over her chest; sulking as Henry and Roland manage to look concerned but confident, and her father smiles with pride as worries that he keeps silent deepen the lines around his eyes. "Head toward Granny's. You'll find them." He calls out in parting as she and the men rush to the mausoleum doors in the room above.

Once outside, Regina pauses only long enough to seal the doors; magically locking her loved ones inside. When that's done, she wastes no time taking Robin's hand in hers and instructing Ron and Harry, "Follow me."

Ron stares agog for ½ a second when she disappears in a swirling vortex of purple smoke He stares until Harry grabs him by the collar and disapparates hastily before there is time to lose his sense of her location.

Regina and Robin materialize in front of the Storybrooke mural on the patio outside of Granny's with Harry and Ron three seconds behind them. Though she isn't surprised to find Main Street abandoned, she wishes she had found differently. It's midmorning. The heart of Storybrooke is usually alive with activity and heavily populated this time of day. She opens the door to Granny's and pokes her head in to find the old woman behind the counter with only two patrons to serve.

"Granny…"

Before Regina can say more, the old wolf tosses a bar towel over her shoulder, places her hands on her matronly hips, and gets right down to business; quickly glossing over any of the usual pleasantries. "Bout time you got back, Mayor. Head toward the dock. Trouble went that way."

Regina nods. "Thanks, Bev." She closes the door and sets out on foot, motioning for the rest of her group to follow. They stride quickly, the four of them shoulder to shoulder, down the center of Main Street.

Henry acknowledges regrettably, "I haven't even had time to teach you anything about the Patronus."

Regina thinks it over briefly and shrugs. "I may not know how to conjure anything like that impressive stag you displayed, but I think I understand the basics. Darkness draws them in. Light repels them. I scared off one yesterday. I can do it again today. Though, I can't handle five of them, not my own."

"Whatever you did yesterday, do it again. Ron and I will help, but we will need a few seconds to set the traps, especially if all five of them are gathered together. We can perform the Patronus if need be, but all that will do is scatter them. It will not capture them."

"I can buy you a few seconds."

"I'm sure that will be essential to our success. Since you disapparate slightly differently than we do, I'm betting magic is different than what we're used to here. We can do it, but we'll need time to compensate for that difference." With just a hint of apology in his words, he admits, "I usually like to have more of a plan in place before going into these things. Not that anything ever goes according to plan – "

Regina nods in understanding. "It's okay. Nothing ever goes according to plan here either. We're used to doing things on the fly."

Three blocks from Main Street the docks come into view along with a sight that causes Regina's heart to accelerate into overdrive and drum loud and harsh inside her ribcage; pumping oxygen-rich blood to her legs as she breaks into a dead run.

Zelena is 50 yards ahead, and down. Laying on her back, on the edge of the dock, about to go over the side with two dementors hovering over her and Emma is a few feet away preparing to blast the things.

Regina yells. "Emma wait! Don't do it!"

Both Emma and Zelena glance her way in profound confusion as the dementors seem to stall momentarily.

"What the bloody hell you mean, don't do it?" Zelena shouts with equal parts fear and anger as her unborn child activates his protective bubble once again. "Have you lost your mind, or do you just want to stand there and watch them kill me?"

Regina ignores her sister's heated words. The element of surprise gives her the extra second she needs to act. Stepping up beside Emma, she raises both hands and unleashes massive amounts of darkness effectively claiming the attention of one dementor. Doggedly, the other remains focused on its original target. Forming a plan in an instant, Regina informs Harry and Ron, "I got this one. You two, help Zelena. To Emma, she says, "They have a trap they need to set up." Regina points to him as she yells, "Follow Harry's lead."

Emma nods. "What about you?" She asks as the dementor glides intimately close, invading Regina's personal space. "What are you going to do?"

Shivering against the encroaching chill of death, Regina lowers one hand long enough to roughly shove her husband a few steps away. Making meaningful eye contact with Emma, she asks, "Remember the Chernabog?"

Emma squints in confusion for a mere second before understanding flickers in her eyes. "Regina no! She objects to late. Even before the words out of her mouth Regina turns her full attention to the hovering hideous black specter of death and whispers provocatively, "You wanna dance? Just you and me; Let's go." Before the dementor can flee, or even react, a spinning vortex of purple smoke envelops both it and the mayor. They disappear and reappear sporadically as they go, like some half-seen apparition appearing fleetingly in the corner of the unsuspecting eye. They struggle and fight, one against the other, each of them grappling for the upper hand until they can be seen no more.

"Bloody hell!" Robin roars in anger as Emma throws up a kind of magical blockade, effectively trapping the remaining dementor between it and the white light erupting from the end of Harry's wand.

Unable to either attack or flee, caught between two layers of light, the ghastly creature moans, howls, and screeches as if it's enduring unspeakable torture.

Emma casts a fleeting glance in Robin's direction. "if she lives, you can kick your wife's ass later. We'll hold him. Get Zelena out of the way, and then help Carrot Top set up the trap."

Zelena grouses. "Don't touch me. I can get myself out of the way, thank you very much!"

Robin shrugs, as Ron extracts two small boxes, each of them half the size of a shoebox from his knapsack and opens one before gently tossing it to Robin who is standing three feet to his left. Following his example, Robin places the box on the ground and backs slowly away as Ron lifts his wand.

"Hold steady, blondie." Ron instructs before informing Harry, "Ready when you are, mate."

The two wizards catch the dementor and imprison it between the magical streams emitting from their wands. Struggling as if they each fight with someone four times their size, they force the dark thing down as it pitches left and right; casting about side to side and up and down relentlessly until Emma catches on and shrinks the size and altitude of her barrier, giving the trapped thing less room to maneuver, less room to fight.

It screeches pitifully, it's noise fading slowly as it loses ground and strength until it finally appears to be caught in a downdraft and gets sucked into the box. After a blinding flash of light, the box slams shut, trembles, and gives the appearance that it is burping as if it now suffers from a bad case of indigestion.

Harry and Ron lower their wands and Emma doubles over, momentarily placing her hands on her knees. Robin wastes no time snatching up the remaining box. "Where the hell did she go?"

Emma pants breathlessly. "Town line."

Harry and Ron squint. "Why?" they ask in unison as Robin places a hand on her shoulder and demands. "Take me there."

Nodding and placing a casual arm around Robin, Emma explains. "She's gonna force it over."

"Over the town line?" Ron queries. "What bloody good is that going to do." And Harry squints. "Exactly, how is she going to force that thing to cross the town line?"

Emma starts to speak then shakes her head. "You wouldn't believe me if I'd told you. It's better you see it yourself." She tilts her head in a – follow me – gesture the instant before magically relocating both herself and Robin.

Arriving a mere ten feet from the road sign that announces, "Leaving Storybrooke." Emma and Robin, Ron, Harry, and Zelena stare, momentarily stunned as they watch Regina, stumble and spin not one, but two dementors around in the necessary direction. With her left hand, she uses light magic to repel the things; keeping them a safe distance away from herself. With her right hand, she casts a wide half-sphere of dark magic around behind them; holding them close, locking them in, and forcing them to retreat in the path of her choosing. She walks slowly, driving the dementors back an inch at a time.

"Holy cricket!" Ron exclaims in quiet awe; sounding very much like his wife. "Harry, She's a… She's a…"

Harry grins in response to the spectacle before them. "She a shadow caster, Ron."

Ron nods; mesmerized. "Yeah, that!" He whispers breathlessly.

Harry lifts his wand and Ron and Emma join in; adding their own barrier of light, which they stretch the entire width of the road and beyond. They expand it further, higher than what Regina can manage on her own while splitting her strength between the light in the dark. When the ghastly creatures are right up against the town line with nowhere else to go but over, Regina drops the dark arc behind them and allows white power to flow from both raised palms in a final dazzling burst as they glide screeching over the town line that is spray-painted a bold shade of orange, and instantly turn to ash that descends slowly and settles in a pile on the road before it disintegrates and completely disappears from existence.

Several seconds elapse before Ron can find the words to ask, "Where'd they go?"

"Into oblivion," Robin says simply.

Emma supplies a bit more. "There's no magic beyond the town line. Therefore…"

"Therefore, magical creatures cannot exist beyond the town line." Harry catches on.

Regina nods weakly as she pants. "One of them was here waiting when I transported in. Probably standing guard in case Zelena decided to leave town. You get yours?"

By way of reply, Ron holds up and gently shakes, the occupied box.

Regina removes her hands from her knees and straightens her spine. Tiredly, she says, "Three down; two to go."

Before anyone can agree or object, heavy dark clouds roll in, obscuring the sun and blue fire erupts out of the dark oily shadow that materializes on the ground the instant before Hades blinks himself into town.

Not caring that they have an audience both he and Robin glare at their wives and demand simultaneously to know, "What the hell were you thinking?"
