Thor and Isolde landed on the roof of Stark tower while Stark attempted to get Selvig to shut the device down.  When that failed he attempted to destroy the machine with his blasters only to get blown back.

"We're too late," Isolde said. "Let me see what I can do."

"Have at it, Svengali." Stark's voice came through the earpiece Fury had provided. 

"I don't understand that reference, Metal man. It better not be an insult," Isolde said as she stepped away from Thor. She began to make her way toward the doctor. Maybe if she could repair the damage to his brain he'd be able to shut everything down. It was a long shot, but it was worth a try. A screech filled the air and Isolde stumbled backward as the Chitari general stepped between her and the man. He appeared to have no lasting damage from Coulson's well-placed shot. Annoyance flared through Isolde with the realization.

"I could use a little help here, Odinson," Isolde said as the being continued to screech at her. 

"Already on it," he answered as he began to spin Mjolnir and clouds gathered overhead. Isolde widened her stance with her shield in front of her and sword in hand. 

The general hissed and fired a blast from his gun. She lifted her shield only for the bolt to go straight through, missing her head by millimeters. 

"Well, then." She tossed her useless shield to the side. "I guess we'll do this the old fashioned way."

"Yes. Let's," Thor said and she glanced over to see a wide grin on his face. A bolt of lightning shot from the sky, striking the machine. 

The impact threw everyone back and Isolde closed her eyes against the bright, glaring light. Getting back to her feet, she frowned to see the device still functioning normally. "That didn't work, Thor."

"I see that, Isolde," he snapped back. 

The general had managed to slip closer to her while she was distracted and he pressed the scepter to her chest. She glanced down before glancing back up with an arched brow. The general shrieked and repeated the action two more times. "Sorry, ugly. Doesn't work on me. Guess mine's bigger than yours."

"I like her," Stark said with a laugh which trailed off. "Shit."

"What?" she asked but answered her own question when she realized a beam of light had shot up into the sky from the device. Everyone looked up to see the hole open in the sky. 

The Chitari made a sound that resembled laughter. 

"Thor, help the metal man," she called without looking at her friend. Instead, she swung her blade at the alien in front of her. Her sword glanced harmlessly off his armor. "Oh, come on," she yelled as he screeched at her. 

She stumbled back, putting more room between her and her foe.

"Holy hell," Raven breathed out as the alien army streaming from the sky came into view. "They must not have made it in time."

Loki leaned against the back of her chair. "This is only a small portion. They will keep coming. They are unrelenting and unending."

Clint glanced at him from the seat beside his wife. 

Natasha looked out the window from behind her partner. "Stark. We're flying into the city at your three. Heading northeast."

"What did you do go for drive through?" he snarked back. 

"How did you know?" Raven asked even as she adjusted their trajectory to bring them in at a better angle. 

"Everyone's a comedian," Stark grumbled. "Go down Park. I'll lay 'em out for you."

"Way ahead of you, tinman," Raven said.

Loki's stomach sank as he took in the destruction in front of them, knowing the part he played in all of this. His eyes darted from location to location looking for any sign of his brother or his love. He resisted the urge to ask after her in the device the archer had given him so he could hear everyone else. 

The jet took out several of the aliens as they flew in front of them. They veered away and flew by a large tower. It was there he spotted Isolde, battling the Chitari general. He gripped the back of the seat in front of him. "You need to get me down there. I have to help her," he said. 

"We're working on it," Clint replied and flipped a couple of switches as Raven changed the angle of the jet. Several rounds were fired toward the general only for him to turn and fire at the jet. His aim was better than theirs and one of the engines exploded in flames. 

"Shit. Hold on," Raven snapped and the three who were not in seats all scrambled for something to grasp onto. 

The jet crashed into the ground tossing them all around. Quickly they were up on their feet and out the back. "We've got to get back up there," Loki said looking at the tower. 

A sound like a sick beast sounded through the air drawing everyone's attention to the portal. 

"No. no. no," Loki breathed out as the hulking beast flew into view. "Too fast. This is all happening too fast," he muttered. 

He had to get to Isolde. Now.

***

Isolde kicked at the general and he lost his footing, falling to a lower part of the roof. Taking advantage, she lunged toward the disheveled doctor. Placing her hands on his head, she fixed his brain as quickly as she was able. It undoubtedly hurt the man as she couldn't use the finesse she was used to. 

"Oh, God," the man said as he came back to himself. "What have I done?"

"We have to shut that machine down," she told him.

He shook his head. "We can't it's impossible."

Her heart sank. Was there no way to stop this invasion?

"We can't do anything without the scepter."

Her head jerked up with those words. "Start talking, doctor."

***

"We've got to help these civilians," Captain America said as they all hid behind a car. 

"Go, we've got this," Natasha said.

"Are you certain you can hold them off?" he asked.

"It would be my genuine pleasure," the archer answered.

"I need one of those flying craft," Loki said as he observed several whizzing by. A plan was slowing forming in his mind. And it was just crazy enough to work. 

"Well, let's see what we can do," Natasha said with a grin.

***

When Isolde went to engage with the general again, she was surprised to find Thor already there. And, of course, the prince wasn't wearing an earpiece so she could tell him to go for the scepter. 

She watched as Thor swung Mjolnir hitting the Chitari on the side of the head. He jerked away with a hiss and dropped over the side of the building. They both ran over to see him fall onto one of the vehicles as it flew by. 

Things just got a lot more difficult. 

"Go," she said to Thor with a jerk of her head. He didn't wait to be told twice.

She watched as vehicles zipped by then dropped onto one with perfect timing. The Chitari on board swung his gun around and she smacked him in the face, shoving him from the vehicle. She took his place and began the search for the general, taking out those she could along the way. 

"If anyone can hear me, we need that scepter. The doctor built in a way to shut down the device but we must have the scepter. Does anyone hear me?"

"Everyone copy? Get the scepter to Svengali," Stark said and Isolde smiled in relief that she had been heard even if she still didn't know what the metal man was talking about.

"Isolde?" was the next thing she heard, surprising her. 

"Loki? Where are you?"

***

The three SHIELD agents and the god were taking out as many invaders as they could while they attempted to get civilians to safety. Loki would use his magic to confuse and distract so the agents could take out the Chitari with more ease. 

Natasha fired her guns while Clint fired his arrows and Raven threw microexplosives, directing them where they needed to go. "Just like Budapest all over again," Natasha said as she emptied her guns once more.

"You and I remember Budapest very differently," the archer said with a scowl as he fired arrow after arrow.

Raven shrugged. "I can see it," she added then pressed a button to blow up more Chitari. "See?"

Clint shook his head. "You two spend entirely too much time together."

Several bolts from an alien weapon fired around them and they all turned as Isolde landed nearby. She nodded a greeting. "I'm here to borrow my fiance if you don't mind," she said. 

Loki hurried over and swung up behind her. She moved aside to let him drive so she could focus on firing the weapon she'd stolen at the enemy. "Find me that general," she told him.

"As you wish, my dear," he answered as they lifted into the air.
