Anastasia walked with Optimus Prime down the hall of Autobot Headquarters in Iacon on the planet Cybertron. After courting for years before the war had even started Optimus finally decided to ask her to be his sparkmate. She had a spark of gold, much like her twin Jaston, and was a strong warrior and medic. She could hold her own in a fight and was also Ratchet's apprentice. The CMO had surprised everyone when he agreed to train the femme. Anastasia was what kept Optimus going throughout the war.

Anastasia didn't know his intentions of asking her, it was to be a surprise that only Optimus and Ratchet knew about. She loved Optimus with all her spark, but she held a dark secret that she and Jaston wished to hide. Her bright red optics were soft and her armor was a light gray. It wasn't a real mystery to figure out why Optimus had fallen for her in the first place. She, unlike most bots, knew that Optimus was taking this war hard. She'd try to comfort him after a battle with his brother. No one knew how the war really affected their leader besides her.

The two bots walked into Optimus' room to hang out. They shared different stories about life before the war for an hour or so before Optimus decided to ask her. He cupped her cheek with his hand, earning a smile from her and she leaned against it. He leaned down so that their foreheads were touching. She was an average sized femme so he was larger than her.

"Anastasia," he started softly. "I love you so much and…will you be my sparkmate?" Anastasia's optics widened and tears crept into them. She knew that sooner or later she'd have to tell him the truth, but she didn't want to right after he proposed.

"I'm…I'm sorry Optimus but I can't." Anastasia whispered sadly before standing. She was about to leave but Optimus held her back. He gave her a hurt and confused look and she knew that she'd broken his spark. "I love you, I swear to Primus that I do, but…"

"But?" Optimus asked. Anastasia's spark clenched at the pain in his voice. She felt awful for putting him through this, but he had to know the truth.

"I'm not really Cybertronian. I come from a planet of shape-shifters. We can take a common form of an alien species. This isn't my real form." Optimus felt like his spark was ripped in two. This whole time the femme that he loved was really an alien pretending to be a Cybertronian. She started glowing and smoke swirled around her. "This is my true form." Standing before Optimus was a large gray dragon with blood red eyes. She was about the same height as her Cybertronian form but her wingspan was large. Optimus stared at her in shock.

"Anastasia…" he was at loss for words. The way he said it made Anastasia turn bot and start crying. He was startled at how upset she was about the situation. Obviously she hadn't wanted him to be hurt or to even find out about it.

"Please exile me from Cybertron." she whispered. Optimus kneeled down next to her as she sat. "Please just do it, I don't deserve to help fight this war or even be with you."

"Anastasia I am upset that you hid this from me." Optimus sighed. He wrapped his arms around her affectionately. "But I can't do that. You still mean a lot to me." Anastasia returned the embrace and just sat there for a while, thanking Primus for locked doors. Optimus couldn't believe that this femme wasn't Cybertronian, therefore impossible for them to bond. His optics closed as he held her tenderly. He knew that she felt guilty for not telling him, he understood that fully. But what he didn't understand was why she left her planet. "Anastasia I must ask you a few questions." He murmured. Anastasia pulled back and nodded. "Why did you come to Cybertron?"

"My planet was destroyed by invaders, only Jaston and I remain of our race." Anastasia said quietly. Optimus' spark was pained for the twins. Their people were dead and they ran to Cybertron seeking shelter. "Optimus, Jaston and I have to leave now that someone knows the truth. We're actually being hunted down and once word gets out that there are survivors, the ones who killed my family are going to stop at nothing to get to us."

"If you stay here you'll be protected. Everyone thinks you're a loyal autobot." Optimus countered. Anastasia couldn't believe it. Even after telling him her dark secret, he still loved her. When he tried to put a comforting servo on her cheek she jerked away. Optimus was surprised by her reaction but didn't try again.

"No, Optimus. You're already in a war, I can't and won't allow you to become involved in this. I'm sorry." Anastasia looked up into his optics. They held so many emotions that she couldn't even begin to decipher. "Jaston and I have to flee Cybertron, no matter how much we'd love to stay. But I don't know how without causing suspicion." Optimus sighed in defeat.

"You're really set on leaving, aren't you?" Anastasia nodded sorrowfully. She hated leaving him but she had no choice. She sent a quick comm. to Jaston telling him of the situation and having him come to the room. When Jaston came in he looked upset.

"So we're leaving?" he sighed. Anastasia nodded. "So how are we going to do this? Just say 'Hey guys guess what! We're not really Cybertronian and if we stay you all will be destroyed!'?" Optimus frowned. His SIC was always making witty remarks.

"I think you should fake your deaths." Optimus suggested sadly. The twins shared a look, knowing how hard the team would take it, but it was their best if not only option. The three of them sorrowfully planned the deaths before leaving to their respective rooms.

**The next day**

Optimus worked on some paperwork while the twins were on their "mission." Anastasia painfully said goodbye to him before leaving Cybertron forever. The autobot leader ignored the sore feeling in his spark, trying to focus on his work. He was interrupted when Jazz ran in with a horrified expression. Optimus looked up at him in worry, but he knew what he was going to say.

"Anastasia and Jaston's bodies were found! Con's killed 'em!" Jazz gasped. The mech looked upset as he watched Optimus go into shock. Optimus stood and ran past Jazz and headed for the med bay. Ratchet stood there near tears in front of the few "remains" of the twins.

"I'm so…sorry Optimus." Ratchet mumbled. Optimus clenched his fists and tears filled his optics. This wasn't acting, he was upset that the twins had left, especially Anastasia. "It was an explosion caused by decepticons." The CMO placed a comforting servo on Optimus' shoulder before leaving him alone.

"Stay safe you two." Optimus whispered before leaving the room with a heavy spark.

So what'd ya think? Loved it? Hated it? Review please!
