Hayley looked at the new mech. He looked like Optimus from the first three Bayverse movies. They had already come to the conclusion that the two sisters were transported to an alternate universe where Cybertronians do exist. And strangely enough, Hayley felt drawn to this mech. She didn't understand it. It was like how she was first drawn to Ratchet.

While Ratchet worked on the counterpart, the two talked through the bond. And when the new Prime was fixed, he and Hayley spoke a lot, getting closer with each other. Hayley healed his mind the same way she helped her sire. Hayley and Ratchet had agreed to allow a three-way bond with the new Prime as well.

In addition, a good version of James Savoy had shown up. Hayley knew by the looks James, Optimus, and Kate looked at each other, they would already form a three-way bond as well. But the most important thing that happened changed their family for the better.

Hayley wanted so badly to surprise her sire. She got jumpy, trying to contain herself. She had told Optimus to cover his optics, well offline them and not look. She had first tried to pull and push the large mech to where he was needed, but that didn't work for obvious reasons.

"Sire, can you help me out a bit without peaking?" Hayley asked.

"Of course Little One. Direct me where to go," said Optimus.

"Okay. There's nothing in the way, so go forward," Hayley said.

Optimus walked forward before being directed to take a left, then a right before stopping.

"Stay there sire. Don't move," Hayley said, motioning for another to come forward. With her Prime's help, she was able to help give this to Optimus. "Okay, open."

Optimus onlined his optics, gasping in shock. He trembled, optics wide. His voice glitched up a bit, not able to say anything. Tears came to his optics, streaming down. The mech took a few steps forward.

"B-Brother...? Is... is it truly you?" Optimus asked.

"My baby brother." Megatron went forward, catching his brother into his arms when he fell. "I'm here now brother. I'm here now."

"H-How?" Optimus asked.

"You have Prime to thank. He freed me and took me to you," said Megatron. "I'm so sorry brother. I wish I could have been there for you. But I ma here now. That's all that matters. I won't ever leave you again."

"I'm so glad you are here," said Optimus.

"I'll leave you two to get caught up," said Hayley, taking her leave to go find Ratchet.

The medic was busy working with Knock Out and Breakdown. Upon seeing his mate, Ratchet stopped and leaned down.

"Hello sweetling," said Ratchet.

"Hey Ratch. Sire loves his surprise," said Hayley.

"Yes, with Megatron coming," said Ratchet, looking away for a bit. He picked up his human mate, walking away for some privacy. "Hayley, I've already spoke to Megatron. You already know I was his mate before we found out he was alive. Megatron knows I love you and our Optimus. He wants us happy. I'm sure he will find another. Ironhide and Alpha Trion have had their optics on him for a while."

"Well, I'm glad he will find another and that I won't lose you. I love you so much Ratchet," Hayley said.

"I love you too Hay," said Ratchet.

Kate looked to James, both knowing something was up with Optimus. They sensed him crying through the bond and got up to see why. They walked outside, going to where Optimus was at. Kate saw him hugging a silver mech. She was confused for a bit, not sure who is was. The mystery mech had to be a new addition.

"Optimus? Are you okay?" Kate asked, coming up to her mate with James. Optimus pulled away, looking down to his mates.

"Yes. Kate, James, this is my older brother, Megatron," Optimus introduced. He turned back to the older mech. "Brother, these are my mates, Kate and James. You've already met my daughter and Kate's sister, Hayley."

"Ah, yes. I remember her. Though it is a pleasure to meet you both," said Megatron.

"Same," said James. "We're glad you're okay Optimus."

"I apologize. I don't mean to worry you," said Optimus. "I will make it up to you two."

"Then I shall leave you to that brother," said Megatron.

"Is it all set up bros?" Hayley asked.

"Yep," said Wheelie.

"Then let's get this plan started. Brains, go get the lights. Wheelie, go get the music ready. I'll go light the candles and get the food out. Then when that is done, go get sire, sis, and Daddy James," said Hayley. "Operation: Romantic Night Out is going to be a blast."

Hayley brought out the romantic dinner, lighting up the candles on the table. She popped open a bottle of Rose apple cider, pouring them into the fancy glasses set out. The lights in the room dimmed for a romantic mood, soft music dancing through the air. Hayley quickly left before her sister came in, Optimus and James following closely behind.

"What is this?" Optimus asked, surprised.

"Let's ask the mini- never mind. They're already gone," said Kate.

"Well, it is for us from what Wheelie said," said James, taking Kate's hand and sitting her down. He took her left while Optimus took her right. "This is rather romantic."

"Indeed it is," said Optimus.

Kate nodded in agreement. The three dug into their food, loving the flavor bursting from each bite. Kate had a feeling that it was her sister that set this up, but she wasn't complaining. It was nice to be able to spend time with the loves of her life. She couldn't have asked for anything better. It was simple and not too complicated. She loved it. Having her mates here just made it even better.

Once they were done, James lifted Kate into his arms. Kate squealed a bit in shock, not expecting him to pick her up. James nodded to Optimus, giving the hint on what he had planned. Optimus smiled in understanding, optics flashing with arousal. James carried Kate to their bedroom, laying her down on the bed with a breath taking kiss.

Optimus climbed into the bed as well, massaging and exploring while James engaged in French kissing. Kate moaned, trying to turn the tables on the two. James saw it coming, pinning her wrists to the bed.

"You're so beautiful like this Kate," James said, kissing her neck. "You should be here more often."

"What if I don't want to?" Kate asked with sass.

"Then we will make sure you do," said Optimus. "You are OURS. No one else can have you."

"I'll always belong to you two, and you two alone," said Kate. "Now love me. You two are such teases. If you don't hurry, then I'll make sure you regret it by getting you both back."

"So sassy. Though I am the one who gives orders," said Optimus.

"Then take me and I won't have to be demanding," said Kate.

The two laughed before both kissed Kate to silence her. They spent the night in passion and love. Both James and Optimus curled around Kate, each wrapping an arm around her as they joined her in sleep. They would never let go of each other. Kate belong to Optimus and James and vice versa. Nothing could break such a strong love.
