The next morning, she was in the lab with Nat, going over the computers again, trying to find anything Ultron may have left behind. She went to be alone again last night, still angry with Steve. She honestly didn't know how much longer she could stay mad at him. Between Ultron and trying to find Bucky, which they were getting nowhere with by the way, and the fighting, Cassidy was just exhausted.

She felt it in her soul bond too. The more she and Steve argued, the more hurt and lonely she felt, and she was sure Steve was feeling the same way too. She already felt the hurt of being away from Bucky, she didn't need to add to it by being angry with Steve.

Steve walked into the lab, handing a tablet to Thor. Someone had killed Strucker.

'And they left a Banksy at the crime scene, just for us." Tony said.

"Why send a message when you've just given a speech?" Nat asked.

"Strucker knew something Ultron wanted us to miss." Steve added.

Nat checked the computer, sighing. "Yeah, everything we had on Strucker has been erased."

"Not everything."

They had brought up boxes full of files that may have something to do with Strucker. Thanks to Steve being so old and wanting to have a paper record of things, they had all the information that was on the computer.

Tony took a file from Bruce, saying that he knew the guy in it.

"He's a black-market arms dealer." Tony said. Steve shot him a look and Tony shrugged.

"There are conventions, alright? You meet people. I didn't sell him anything." Cassidy didn't think he sounded very convincing.

"Thor pointed to the picture. "What's this?" He asked.

"Uh, a tattoo, I don't think he had it." Tony told him. Thor shook his head.

"No, this is a tattoo. This is a brand"

They scanned it into the computer and Bruce was running it to see if it popped up anywhere. "It's a word in African dialect meaning 'thief'" Bruce told them.

"What dialect?" Steve asked.

"Wakanda." Cassidy watched as Tony and Steve shared a look.

"If this guy got out of Wakanda with some of their trade goods…" Tony began.

"I thought your father said he got the last of it." Steve finished.

"What comes out of Wakanda?" Bruce asked. They followed Tony and Steve's gaze to the shield.

"The strongest metal on earth."

Apparently the 'nose goes' Cassidy gave out earlier about not going after the scepter again wasn't gonna fly. Even Steve told her they needed her to come, which got him some brownie points. Not much, but some.

The jet landed, Bruce staying on it unless they needed a code green. Tony surveyed the area while the rest of them made their way into the main ship, where Klaue and most likely the Maximoff's were.

They carefully climbed into the ship, subduing the men they had on guard. Cassidy went around with Nat, up top while Clint went around the other side. She could hear the Maximoff girl talking to her brother, but she couldn't make out what she was saying.

"Stark, he's a sickness!" Ultron yelled.

"Aww." Tony said. "You're gonna break your old man's heart."

"If I have to."

"Nobody has to break anything." Thor told them.

"Clearly you've never made an omelet."

Cassidy rolled her eyes at Nat. Maybe Tony and Ultron were more alike than they thought.

"He beat me by one second." Tony joked.

"Focus Tony." Cassidy said into the comms. Tony could banter with him all day and they'd never get anywhere.

The Maximoff boy stepped around his sister, coming up to stand next to Ultron. "Ah yes, he's funny. Mr. Stark. It's what? Comfortable? Like old times?" He said, looking down at missiles.

"This was never my life." Tony told them.

"You two can still walk away from this." Steve offered.

"Oh, we will." The girl said. Steve tried to reason with them, but Ultron wasn't having any of it. Cassidy looked around and saw Ultron blast Tony out of the way as gunfire erupted on the ship. Cassidy jumped down onto the platform and shot two in the chest before she was grabbed from behind. She threw her elbow back into the guys nose, then turned and shoved her knee into his gut, tossing him off the platform.

She turned to help Nat but the Maximoff girl was in front of her. She went to raise her gun but the girl raised her hands and Cassidy was on the ground, holding her head.

Cassidy opened her eyes and she wasn't on the ship anymore. Looking around she realized she was on the Helicarrier in DC. There was fire and falling debris all over and she struggled to stand.

She heard Steve's voice yelling so she ran to find him, only to see Bucky standing over him, punching him in the face.

"I'm with you, until the end of the line." Steve told him. Bucky should have stopped then. He did stop. But this wasn't Bucky. He wasn't in there at all. This was all Winter Soldier.

"Steve!" Cassidy yelled, taking a few steps toward them.

"Sweetheart stay back, I don't want you to get hurt." Steve said, his voice cracking. The soldier went in on him again, ignoring Cassidy's screams.

"Bucky please stop! This isn't you! Please don't to this, you can fight it!"

He ignored her and kept hitting Steve, so much that his face wasn't recognizable anymore. The soldier took his metal hand and wrapped it around Steve's throat. Cassidy willed herself to shoot him, to run, to do anything, but she was frozen. Forced to watch one of her soulmates kill the other.

Steve's lifeless body fell to the glass and Cassidy let out a strangled cry. That got the soldier's attention and he started walking toward her. She tried to move again but she couldn't. This was it; he was going to kill her and there was nothing she could do about it.

He stopped mere inches from her face and looked down at her.

"Please." She pleaded, "You don't have to do this. You're my soulmate, you're all I have left now." She whispered.

"You're my mission." He told her, bringing the metal hand up to her neck. She closed her eyes as the fingers wrapped around her throat, but then snapped them open when the floor fell out beneath them.

She didn't know if she would survive the fall, but the last thing she thought of before she hit the water was Steve's face, and how she'd never see him again. Then she saw nothing.
