AN: I'M SO SORRY! I didn't notice that this Chapter got wiped away. This, of course, gave me a chance to change a bit the chapter, but I'm glad I managed to fix it. Now enjoy!

The ground bridge opened to the Omega one base where others were waiting for Autobots to return with their leader. First to come in were Jack and Arcee then one by one Bumblebee Bulkhead and Ratchet until finally the 'bot that they waited; Optimus Prime himself along with Elena on his shoulders.

"Optimus?" Raf asked to make sure he does remember them.

"Hello, Raphael," he replied kindly to youngest human. The kids were all glad to realize he was back. Optimus, however, was wondering what he has missed since he had Decepticon symbol.

"Optimus, it has truly been our darkest hour, but know this: from every indication your spark never ceased being that of an Autobot," said Ratchet to him before everyone welcomed him back.

Elena was so happy to have father back. After losing one, she was glad that she hasn't loosed another. In this, she hugged him by his neck hiding her face from him and from others.

"Elena?" asked Optimus confusedly.

"You have no idea how much this means to me, father," she said, while tears had started to appear in her eyes.

Optimus was surprised to hear that. She called him father. Normally, as Orion Pax, he would have been leaking by overjoy, but as a Prime, he simply smiled and rested his hand on her. He may not remember what happened, but he could guess she has feared to lose him as well.

"I won't ever leave you like that, my child," said Optimus. Hearing this, Elena let her tears fall down from her face. Without anyone noticing the tears change a bit her left arm and leg add some pink line and changed her right optic to look like her real eye.

Others simply smiled for them. Knowing what was told to them and what has happened, they deserved this moment.

"So, does this mean a Welcome party?" Miko suggested.

"Miko!" Elena shouts while dried her tears.

"Primes don't party." remind Jack.

"Like a father, like a daughter," said Agent Fowler. Everyone chuckled and agreed to that.

SweetStar simply watched from the side the happy reunion. Elena was officially a Star. Who knows what else is waiting for her and for the Team.

In night-time, humans had returned to their homes. Autobots had to check themselves in sickbay and like expected, some dents here and there, few scratches. Some painkillers and a good night sleep should be enough for everyone.

Optimus just came from the shower from his bathroom, before he heard knocking on his door. He went to open it and find Arcee behind the door.

"I'm sorry to bother you, sir," she said, while looked away blushing to realize he just got from the shower, having nothing but a towel around him. "I-I just came to talk..."

"Okay," he said letting her enter to his quarters. She first stood there, since she wasn't sure if she would sit or not. After closing the door Optimus came to her. "What you wish to talk about?" he asked. She blushed a bit more since he was still wearing only a towel.

"I...I failed you, Optimus," she said and looked down.

"Failed me? On what?" he asked confusedly.

"On Elena," she said. Optimus was still bit confused. He moved to his berth and sat on it to listen well what she was talking.

"Arcee, what happened?" he asked. In this Arcee came front of him without looking at him.

"You asked me to look after Elena until you return, right?" she said.

"Yes," he said. "You asked me to promise that I will before you agreed to." why she is telling this could it be something to do with the Decepticon symbol on his armor. "Did something happened?" he asked.

Arcee started to tell him, about what happened after they defeated Unicron. How he didn't remember them and went with Megatron. How they were all worried, mostly her and Elena. How they tried to find him in many days. How Elena get herself into the warship. How they tried to get to Cybertron and there to Vector Sigma. All to the point where they got their him back.

Optimus was speechless. All that happened and all that pain it caused to the team. Especially to his little girl and especially to Arcee.

"I couldn't look after her," she said while tears started to appear in her optics. "I should have stopped her back then, but she just she knew that we needed to get to Cybertron. She wanted to make things less worried for us, but she caused more worries for me and SweetStar. I..."

She was cut off by Optimus who gave her one passionately kiss

"No, Arcee," he said. "You have no reason to be sorry. I let it happened. I should be the one to ask an apology."

"You did it to protect us all," she said. "None of us didn't see it coming."

"You didn't either on Her," he said. "I know it was too dangerous, I don't blame you for it. You did best you could to look after her."

She only nodded quietly before she felt once more his lips on hers. Gosh, how she missed him kissing her. She never gets enough of it. Before it could get any heated, he broke the kiss.

"I guess I need to make it up all this to you," he said.

"Perhaps..." she said before he moved her to his berth.

M rate in this part.

Early in the morning, Optimus woke up finding Arcee next him. He couldn't help but admire how beautiful she looked during her sleep. He just stood there watching her, before he caressed her face and gave a kiss on her helm. In this, she started woke up as well.

"Morning, sir," she said.

"Morning," he said giving warm smile. She just loved when he gave that smile.

"What you think she would say about us?" she asked.

"Hard to tell. How she reacted to our first Interface?" he asked.

"She took it pretty well," she said. Then something else came to her mind. "You think she will start to call me a mother?" Both starts chuckled at that idea.

"I think you should ask that from her," said Optimus before he started to kiss her passionately, which she responded in the same way.

"Dad, I Think we need to talk about..." heard a voice of Elena, who came out from her room and stood up right there, once she spots them. They both stopped making out, while Arcee tried to cover herself and Optimus got up. There was deep silence.

"Scrap..." said Arcee and put her hand on her face.

"Elena, don't you dare..." said Optimus.

"Okay," she said blankly. "Excuse me..." she said before she went back to her and close the door. Then huge scream was heard from the door. It was hard to say first what she was yelling, actually, it was just yelling.

Optimus look on Arcee.

"Took well?" he asked amusedly. She could help laugh a bit on that.

Most of the day Elena didn't do anything if not laying on the couch. Kids tried to ask what was wrong with her, but no one didn't answer. Others had a pretty good guess what was wrong with her, but they didn't tell the reason.

REVIEWS, PLSS ^^

AN: There *sigh* I was so worried about this.
