Same Night: Roxxon Norco
Outside: Catwalk
Dipper continues running towards where Pacifica on the platform is being moved. Pacifica gasps as she holds on and glances back, Dipper running full speed, panting. He doesn't think twice before turning, jumping, and landing down on a metal crane. He grunts when he lands.
Mabel's voice tells Dipper, "The President is secure, Dipper. I'm clearing the area."
Dipper replies, "Nice work."
Wendy's voice asks them, "What about Doctor Fenton?"
Mabel's voice confused, "Wendy?"
Dipper answers Wendy, "I had Jarvis take her out of here."
Mabel's voice asks them, "Should I know how and why you're here, Wendy?"
Wendy's voice answers, "Uh, I'm in the middle of a fight right now, Mabel. That question will have to be answered later." Dipper rolls his eyes at the answer.
Back in her Iron Woman suit, Mabel sighs in annoyance at Wendy's answers before turning to the President, holding his waist.
Inside: Mabel's Iron Woman Suit
Mabel looked at the President, "Ready, sir?"
Outside
The President puts his arm around Mabel's suited shoulders as he asks, "What do you mean 'ready'?" Before he can finish his sentence, Mabel/Iron Woman takes off, making the President scream at the sudden move.
Dipper climbs up the ladder, Pacifica whimpering as the platform moves closer to the end. Dipper climbs and steadies himself on the railing. Dipper reaches up to Pacifica and tells her, "Pacifica, I got you." Pacifica leans down, holding onto the pole with her left hand and reaching her right hand out towards Dipper, "Relax, I got you." Pacifica screams a bit as she tries to reach down. Dipper tells her, "Just look at me!" The platform stumbles, making Pacifica groan as she swings a bit. Dipper tells her desperately, "Honey, I can't reach any further, and you can't stay there. All right? You've got to let go." Pacifica hesitates to let go. Dipper shouts, "You've got to let go! I'll catch you, I promise." Pacifica nods. The platform stumbles again, and Pacifica yells as she slides out, her fingers brushing Dipper's. He yells, "No!" Pacifica screams as she falls into the fire, where the container explodes. Dipper has tears in his eyes, shocked and hurt, as he watches the love of his life fall to her death.
Across the catwalk, Bill, with the EXTREMIS running through his veins, casually walks up the stairs onto the catwalk as Dipper jumps over the railing to stand on the catwalk, looking down as he's still in shock that Pacifica's gone.
After a moment, Dipper looks up to see Bill standing at the end. Bill says loudly, "A shame. I would've caught her." Dipper's expression is hard as he walks toward him.
Bill narrows his eyes a bit and starts walking fast before full-on running. Dipper starts running. Bill raises his arms and jumps up. Dipper quickly drops and slides underneath. Bill lands on his feet, turning to face Dipper, who stands up, stepping into a suit that flies down and opens up for Dipper.
Wendy blasts an EXTREMIS soldier as she flies past a catwalk. She flies up and suddenly gets grabbed by an EXTREMIS woman 4. Wendy gets caught off guard and falls as the woman straddles and punches her twice before the woman raises and heats up her hand.
Inside: Wendy's Suit
Wendy's eyes widen, and she tells JARVIS, "Jarvis, eject."
Outside: Sky / Catwalk
Wendy falls out as she's ejected out of the Iron Man suit as EXTREMIS woman 4 punches through the chest reactor, but looks confused as she sees Wendy fall out before jumping off the suit onto a catwalk.
Wendy turns, holding her arms out. She yells out, "Jarvis!" An Iron Man suit near her turns its head and scans before quickly flying down to her.
Wendy's eyes widen as she sees she is close to the ground. The Iron Man suit then opens and flies under Wendy. She falls into the suit and quickly activates the thrusters as the suit closes up around her.
Wendy flies up fast and lands on the catwalk behind EXTREMIS woman 4, who turns around to face her and starts running to her. Wendy punches woman 4, who then elbows Wendy in the face, making her fall on the floor.
EXTREMIS woman 4 stands over her, raising her right hand to punch Wendy until something blasts EXTREMIS woman 4's right arm off.
Wendy gasped as EXTREMIS woman 4's right arm fell to the ground. EXTREMIS woman 4 flinched and screamed as her orange eyes shot open, seeing her missing right arm. Her screams faded as she was shocked by what she was seeing.
Wendy's Ruby suit was standing on the catwalk, raising it right hand towards the woman. The woman fell to her knees, unable to scream or whisper. Her wide-open eyes looked up. The Ruby suit was looking straight into her eyes as it said, "Now you're unarmed... dick."
EXTREMIS woman 4 looked at the Ruby suit as the EXTREMIS grew her arm again. She clenches her teeth before getting up and ready to fight the Ruby suit until Wendy blasts a large hole in the EXTREMIS woman 4 chest. Wendy crawls back as the woman falls dead on the catwalk.
Inside: Wendy's Suit
With a cut above her left eyebrow, Wendy is breathing hard as she looks at dead EXTREMIS woman 4 with a stern expression.
Outside: Catwalk / Sky
Wendy silently stands up. She glances up to see her Ruby suit walking towards her. Wendy's mask opens as she quickly aims her hand at the Ruby suit.
The Ruby suit yelled, "Woah! Don't shoot!"
Wendy hissed, "You have three seconds away from getting shot! Who are you, and what are you doing in my suit?!"
The Ruby suit's mask opens, revealing that it is Candy in the suit, "Wendy... it's me."
Wendy looked at Candy, bewildered by this encounter, "Candy... w-what are you... h-how..." Wendy was left speechless as she was overwhelmed with conflicting emotions. She limped towards her with tears in her eyes and hugged her tightly, "I thought you were gone... I'm sorry, that's not what I should worry about."
Candy hugged her back and smiled, "No, it's okay."
They both stopped hugging each other as Wendy wiped the tears from her face and sniffled. She then looks at Candy and asks, "Candy, where's Phillip?"
Candy answers her, "I took him to my parents house so they can watch over him. Don't worry. He's safe."
Wendy sighs in relief, "Oh, thank god."
Candy asks her, "So what happened in your house after I got shot?"
Wendy answers her, "I don't know. I saw you get shot in front of me. Then the next thing I know, I found a woman outside holding a gun, so I went out there and tried to kill her."
Candy looks at her in disbelief, "Why didn't you take Phillip to safety first?!"
Wendy replies, "It was a long ass day! I needed to figure out what the hell just happened! I thought you were dead, Candy! I lost my cool, okay?" Candy remained silent. Wendy wiped her eyes again and apologized, "I'm sorry."
Candy says, "Hey, I'm sorry. No need to apologize for that. I would have done the same thing."
Suddenly, Wendy hears footsteps behind her. She quickly turns her head to see two EXTREMIS soldiers run towards them. Wendy turns to look at Candy in her Ruby suit, "You know how to use my suit, right?"
Candy answers, "Yes... Dipper has shown me how to use these things."
Wendy nods at her, "Alright, let's fly."
Their iron face masks close as they quickly activate their thrusters, flying straight up. The two soldiers stop running, looking up to where Wendy and Candy/Ruby flew off to before both of them get blasted by an Iron Man suit.
Dipper/Iron Man turns to face Bill, who backhands Dipper/Iron Man in the face. Dipper/Iron Man retaliates and punches him in the face. Bill takes off a layer of metal on Dipper's Iron Man right arm before swinging to punch Dipper/Iron Man in the chin, but Dipper/Iron Man quickly moves his head away and tries to blast Bill, who smacks his hand away, making Dipper/Iron Man miss.
Dipper/Iron Man swings his arms to punch Bill, who moves his head back and punches Dipper/Iron Man in the ribs, taking out another piece of metal. Dipper/Iron Man swings his arm back and elbows Bill in the face before grabbing the back of his neck and pushing his head down to the railing, but Bill grabs the railing, stopping Dipper/Iron Man from hitting his head, the EXTREMIS heating up the railing, making it sizzle.
Bill moves away, grabs Dipper/Iron Man's hand, and rips the metal off his hand, throwing it away. Dipper/Iron Man goes to punch Bill with his other metal hand, but Bill punches his metal fist, making Bill's forearm break, and he groans in pain as the EXTREMIS heals him. Dipper steps back from the push of the punch.
Bill runs and pushes Dipper/Iron Man off the catwalk, breaking the railing behind Dipper/Iron Man to a platform below. Dipper/Iron Man lands on his back. Bill quickly jumps down and lands on top of Dipper/Iron Man.

Dipper grunts, feeling the impact as Bill lands on him.
Outside: Catwalk
Bill raises his EXTREMIS arm to punch Dipper/Iron Man.
Inside: Dipper's Iron Man Suit
Dipper demands, "Eject." JARVIS pushes him out.
Outside: Catwalk / Sky
Dipper ejects out of the Iron Man suit and slides out of the platform just as Bill punches down, hitting the suit's chest reactor. Bill looks confused when he sees an empty suit, taking his arm out.
Dipper falls and turns as another Iron Man latches onto him. Dipper/Iron Man activates his thrusters before he hits the ground and flies up to where Bill's looking down by the railing. Dipper/Iron Man grabs him, flying up and hitting the platform above them, making Dipper/Iron Man let go of Bill, who backflips mid-air before landing on his feet. Dipper/Iron Man back rolls before going on his knee.
Bill is standing up, now shirtless. The EXTREMIS glows in his chest, where his dragon tattoos are visible. Dipper blasts at Bill, who jumps out of the way before somersaulting toward Dipper, who stands to punch Bill.
Bill ducks and punches a part out of the metal of Dipper/Iron Man's abdomen and then punches again, taking out the other part. Bill goes to punch again, but Dipper/Iron Man dodges and pushes Bill to a metal-cable wheel behind him. Bill watches as Dipper/Iron Man raises his hands and blasts toward him. Bill's eyes widen, and he moves out of the way.
Dipper/Iron Man then steps up and raises his right hand to blast Bill, but he quickly grabs Dipper/Iron Man's hand and twists it to blast Dipper/Iron Man in the face. The blast pushes Dipper/Iron Man off the platform, but Dipper/Iron Man quickly activates his back reactor, making him steady before grabbing Bill's wrist as he goes to punch him. Dipper/Iron Man knees him in the gut, making Bill lean forward, and Dipper/Iron Man quickly activates his left foot thruster to knee Bill in the face, making him grunt.
Dipper/Iron Man then activates his hand thruster to backhand Bill. Dipper/Iron Man kicks up at Bill's back, but Bill grabs his leg, turns, and raises his EXTREMIS hand. Dipper quickly takes his leg out of the suit as Bill chops the metal leg off, and Bill hits Dipper/Iron Man with the metal leg before throwing it away.
Dipper/Iron Man goes to punch Bill, who grabs his arm, moving it away before grabbing him, jumping up, and flipping Dipper over. Bill smugly walks closer to Dipper/Iron Man, who goes on his knees and quickly tries to blast him, but Bill grabs his metal hand, moving it away with a tight grip.
Inside: Dipper's Iron Man Suit
Dipper groans at Bill's right grip on his wrist.
Outside: Catwalk / Sky / Ground
Bill looks down at Dipper/Iron Man, "Well, here we are on the roof." He raises his hand, heating it up, and goes to slice Dipper/Iron Man, but Dipper ejects out of the suit and falls back as Bill slices through the empty suit.
Dipper falls and lands on the platform below. Bill looks down at him. Dipper then looks up as he hears something in the distance.
JARVIS's voice informs Dipper, "Mark 42, inbound." The suit flies into view.
Dipper, staring at the suit impressed, mutters, "I'll be damned. The prodigal son returns." The prehensile suit flies closer as Bill watches. Dipper gets up to his knee, reaching his right arm back, waiting for the suit to come to him. As the prehensile suit gets closer, it tries to balance itself before it hits the pole and breaks apart. The pieces land beside Dipper. Dipper looks over to the pieces, sighing in annoyance before looking up to see Bill, who's giving him an amused disbelief look. Dipper rolls his eyes, "Whatever."
Bill shakes his head a bit, saying to Dipper, referring to Pacifica, "You really didn't deserve her, Dipper." He's looking down at Dipper, "It's a pity. I was so close to having her perfect." He jumps down to the platform, making Dipper quickly stand up.
Dipper holds his arms out, "Okay, wait, wait, wait! Slow down! Slow down!" He tells Bill, referring to Pacifica, "You're right. I don't deserve her." Bill looking at him amused, Dipper lowers his arms, "Here's where you're wrong. She was already perfect." Dipper quickly kneels down as he motions his arms up, the pieces of his prehensile suit activating. Dipper signals towards Bill, who starts walking towards Dipper, raising his arm to punch him. The prehensile suit attaches to Bill, flying him up to the wall, Bill straining as he struggles to move. Looking up at Bill, Dipper commands, "Jarvis, do me a favor and blow Mark 42."
Bill screams, "No!" He gets cut off by the helmet closing around his head.
Dipper jumps off the platform to a metal bar and slides down as the prehensile suit explodes, taking the entire platform with it. Dipper screams as he jumps off the metal bar and falls into a suit that barely latches onto him.
