"And how do you plan to get past the rest of the Alphas? They won't just stand by and let you have a heart-to-heart with dear old dad."

Derek stepped closer to Gabriella, his tone serious. "If you're going in, we're going in with you. But we need a plan. If we're ambushed, it'll all be for nothing."

"Then let's come up with one," Gabriella said, her voice steady as she turns to face scott "are you in or are you out"

"I don't know about lucas. But if Boyd's still alive, we have to do something. We have to try"

"But?"

"Who's the girl? The one locked in with Boyd?"

"I guess we're going to find out"

[...]

Making a cautious approach through the alley behind the rear of the bank, Scott, Erica, Gabriella and Derek pause beneath the fire escape.

Scott reaches for one of the rungs, but then notices something "Now I kind of wish we'd let Stiles come"

Gabriella looked at him confused "Why?"

"Because he'd be able to come up with something better than I told you so"He points to the BANK NAME and LOGO on the rear door.

The same exact symbol bruised onto Allison and Lydia's arm.

Gabriella rolled her eyes "Shut up and climb"

Grabbing hold of a ladder rung, Scott pauses again "Something I can't get out of my head"

"The moon's rising, Scott. What is it?"

"Risk and reward"

Erica looked at scott in disbelief "are you seriously quoting coach"

Scott sighes and explains "We're not measuring the risk with enough information. We don't know enough"

"We know time's running out"

"But think about it. They put the triskele on your door four months ago. What have they been doing all that time? Why wait until now?"

"My dad is a grade A psychotic asshole, he likes to torture his victims before killing them...he likes making them suffer and I know what I'm risking. My life for theirs. And I won't blame you if you don't follow me"

Gabriella grabs the steel rung of the fire escape and begins to climb as Derek and Erica follow when they reached up  With a last glance at the rising moon, Scott reaches
up to follow.

[...]

A thin shaft of light falls over the interior stone of the vault.

The wall shakes with a low BOOM, something hitting it from the inside. Another hit and a CRACK ripples through the stone.

With a sudden CRUNCH, a FIST SMASHES through. Stone crumbling outward, Derek bursts into the dark vault.

Right behind him, Gabriella, erica and Scott tumbles in through a dissipating cloud of dust.

"Boyd?"

From the opposite side of the room, a DARK SHAPE inches forward. A hulking figure, its breath harsh and ragged.

"Boyd, it's me. It's Derek"

A BUZZING snaps Scott's attention to his pocket. He fumbles for his phone "Stiles, now is not a good time"

Gabriella takes a cautious step toward TWO FIGURES in the dark.

One is Boyd, struggling to keep the transformation at bay.

Gabriella watches the MOONLIGHT spill across the floor of the vault, seeping in.

"We got a problem. Really big problem" Scott said

But Derek didn't hear him, a look of shock spreading across his face "Cora?"

They all look at him confused "Who?" Erica asks

"Cora?"

A dark-haired, beautiful young woman also struggling against the moon steps into the light.

Her name is CORA HALE "Derek, get out. Get out of here"

Gabriella eyes focus on an odd, powdery SUBSTANCE lining the baseboard against the wall of the vault.

"Oh damn..." her follows the line of MOUNTAIN ASH to the vault door. It lies open, moonlight seeping in.

A SILHOUETTED WOMAN appears just past the threshold of the vault.

She opens her hand, letting the last bit of ash fall from her palm "No--no, wait!"

But even as she starts forward, the barrier connects, stopping her in her tracks.

On the other side of the vault, Boyd lets loose an enraged snarl, GLOWING YELLOW EYES locked on Derek.

Cora's head jerks up, fangs bared as the transformation takes hold.

Claws unsheathed, Derek and erica raise their hands to defend themselves.

Boyd goes to attack erica but gabriella steps in and throws him against the wall

Derek lurches forward, SLASHED in the back by Cora. She comes at him, swiping with razor-sharp claws until Scott crashes into her, dragging her down.

Derek pulls Scott back to his feet "You know her?"

"My sister--younger sister"

"What the hell's she doing here?"

"Like I have a clue? I thought she was dead"

Past them, the two werewolves--silhouetted figures with GLOWING YELLOW EYES--rise for another assault.

Catching a scent, Gabriella turns back in surprise to see Allison standing just outside the vault door.

"Look out--" Allison yelled out as Boyd jumps at Gabriella but she SMASHING him against the wall.

Cora runs in Derek's way, attacking with
renewed ferocity.

Allison watches in horror at the scene infront if her, Gabriella sees Allison approach the

MOUNTAIN ASH BARRIER "No, don't--don't break the seal!"

"Boyd!" Allison called out making him spin, YELLOW EYES, focusing on her.

Allison whips her hands across the seal. The MOUNTAIN ASH swirls up into the air and a break appears in the barrier.ROARING, Boyd charges toward her.

Allison whirls back behind the safety of the vault door as both Boyd and Cora hurtle out
of their prison, racing for freedom.

With their FERAL GROWLS growing fainter in the distance, Allison steps out from behind the door and is GRABBED by Gabriella "What the hell is wrong with you"

"Don't touch her" Scott yanks Gabriella's hand from her, locking eyes with him. Gabriella shakes free of Scott's grasp, glaring at Allison.

"What were you thinking?"

"That I had to do something"

"She saved our lives" Scott defended her

"And what do you think they're going to do out there? You have any idea what we just set free?" Derek said

"You want to blame me? I'm not the one who turns teenagers into killers"

"atleast he doesn't torture the innocent teenagers" Gabriella said Leaving the vault trying to find lucas.

Carefully moving around a corner, Gabriella peers about the cavernous bank as Erica follows

She continues on, glancing back with every
few steps. But she stops short "do you smell that?" Gabriella asks

"Yea...yea I do"

The smell was coming from the closet door they push it open and slip inside

Squinting in the dark, they turns to find--
Lucas's dead and contorted face.

Gabriella sucks in a shocked breath at the sight. Paralyzed in an expression of terror,

Lucas looks as if he must have faced something truly horrifying in his last moments.

Hands rising to her own mouth, erica retreats back, trying not to scream as well.

Gabriella staggered back, her heart racing as the reality of what she was seeing crashed over her like icy water. Lucas's lifeless body lay before them, contorted in an unnatural position, a haunting reflection of the terror he must have experienced.

"No... no, no," Gabriella whispered, tears welling in her eyes as she took a step closer, unable to look away. She felt as if the ground had dropped out from under her, the weight of despair crushing her chest.
