For visual purposes, here is how I created my version of Robin through all my playthroughs: Build 1, Face 4, Hair 3, Hair Color 12, and Voice 2

PART 1

She stood before him with her sword drawn. She was fully prepared to do what must be done...or so she thought.

" Don't make this harder than it already is Robin...please" Lucina said

She had grown close to Robin in the short time they knew each other. She believed in her heart that her convictions for this course of action were justified. She tightened her stance, hoping that confidence would flow from the sacred blade into her. Robin looked up at Lucina, and their eyes met. She saw no ill intentions in his face, which surprised Lucina somewhat. The way his eyes glistened from the setting sun's reflection took hold of Lucina's focus.

"Lucina, I understand your decision in wanting to do this. If it is indeed true that the version of me from your time is a traitor to Chrom and all of our companions, I would enact the vengeance myself. However as that is not an option, all I can ask is for you to do is not take my life. Let me prove myself to Chrom..."

He smiled tenderly at Lucina as he took a step towards her. He moved slowly, in order to show he was no threat to her. Lucina instinctively backed up a few steps in response.

"...and let me prove myself to you Lucina."

"Robin...I..."

Lucina was startled by his words, as she was not expecting this kind of interaction when she played this scenario in her head. Robin took another step forward towards her as he continued his speech to the Ylissean princess.

"In the end, if you feel you can not trust me and this is the only option you see as just...please know that I would gladly give my life for Chrom's sake. However, I...

Robin paused his speech and took another step towards Lucina. His smile never faltered once.

"...would also give my life for you Lucina."

A gust of wind flowed through Lucina's hair as his words took her by surprise. She wondered why Robin was telling her such things at a time where his life could end at any moment.

"Wait...what...?"

Robin looked at Lucina and wondered how to continue this conversation. The woman before him had her sword at the ready, and one wrong move could cause her to strike at any moment. He decided that if this was indeed his last day to live, he would tell her his feelings. The feelings...he has for her. The feelings that he had so long kept hidden in his mind, heart and soul. He took a small step forward.

"Lucina, since your arrival, I was always curious about you. You are an amazing warrior, and a powerful ally to our cause. Those were my initial thoughts about you. When your companions from another time arrived shortly after, I was very intrigued to learn about the version of our world you came from. I learned a lot from our discussions, and found myself creating strategies in the event of future similar situations. However...over time I looked forward to our time together for different reasons. My thirst of knowledge was strong, but not for your world...but...for you … Lucina."

Lucina slowly lowered her guard. Robin's words stunned her once again. She was unsure if Robin's monologue was meant to distract her from the task at hand, or if his words were sincere. She kept eye contact with him the entire time.

"Robin, what are you saying?" Lucina inquired.

Robin took another small step forward to which nearly closed the gap between them. He smiled warmly at her, as the gloss in his eyes had her full attention. He took a deep breath, and proceeded with his confession.

"I'm...in love with you Lucina...madly in love with you." Robin said bringing a hand to her cheek.

At this point, Lucina was in total astonishment. She had never expected to hear these words spoken to her, let alone come from someone she drew her sword against. However, this wasn't just some random enemy, this was Robin. The man who served as her father's military tactician as well as his closest friend. Though he is the one who brought great calamity to her world, this wasn't the same person. This was a person who loved her father, loved this world, and now who apparently is in love with her.

"I'm sorry for telling you this now, trust me my timing couldn't be any worst. But if I am to die today, I wanted you to know how I felt."

Robin reached out with his other hand to grab the tip of Lucina's Falchion. He quickly brought the tip of the sword up, holding it within inches of his throat.

"ROBIN STOP! WHAT ARE YOU DOING?!" Lucina shouted trying to pull her sword away.

"Just...promise me you'll find someone else who cares for you. I want you to be happy Lucina. That's all I want for you." Robin said still holding the tip of the Falchion.

Robin closed his eyes and prepared himself for his untimely death. If this were indeed his last moments alive, he knew he would die at peace. The evening wind stopped flowing momentarily. Everything was at a standstill. Lucina was the only one who could decide his fate at this point. She too felt frozen in her indecisiveness. This was a moment for her to change the fate of this world, in order to prevent history from repeating itself. She looked at the man in front of her, who just confessed his romantic feelings .. his love for her, and was willing to die if she deemed it necessary. The thought of killing someone she had grown close to was haunting. She felt her body buckle from underneath, as she fell to her knees releasing the grip of the Falchion. Her hair covered the pain that was clearly visible in her face. She looked at the ground as her eyes began to welled up with tears.

"I'm so sorry Robin...I'm sorry...please forgive me...I..." Lucina sobbed.

Her tears flowed from her face and trickled down onto blades of grass beneath her. Robin knelt down on one knee in front her, and placed the blade he was hold in front of her. Lucina looked up at him, and saw that same warm smile he dawned earlier. She was in awe with Robin; how could he possibly be smiling, when he could have died moments ago? He reached his hand out and wiped a tear from her face. The same way Chrom did when she revealed her identity to him. Robin noticed that the brand in Lucina's eye had an amber tint to it. He was unsure if it was mixed from the sun's reflection or if it was a natural occurrence, but he found her even more enchanting.

"Easy now Lucina, it's alright. I know your intentions were just in this course of action. Please don't cry anymore." Robin said as he stroked her hair.

Lucina's face was flushed from all the emotions that overcame her. She felt fatigued from the events of the last few minutes, she found her self leaning into Robin. Her head was now buried into his chest, as she tried to regain the strength to think clearly. Robin was so focused on Lucina, he was unable to hear the grass behind he rustle with the movement of heavy boots. At the last second he looked up to see a familiar face staring back at him. Lucina raised her head in response to Robin's body shifting.

"Well, this was surely unexpected."

"CHROM!"

"FATHER!"

Both exclaimed at the sight of the Ylissean Prince. He stood before them with a half smirk forming in the corner of his mouth.

"Good evening Robin. Good evening Lucina." Chrom said nodding to the two of them.

"Chrom...how long have you been there?!"

"Long enough to see my daughter have her sword pointed at you. I thought you both were going to spar or something of that nature. Never did I expect to hear...well .. what I heard..."

"Father, please let me explain!"

Chrom extended a hand to Lucina, helping her to her feet. Lucina knelt down to grab her Falchion, returning it to her belt.

"There's no need to explain Lucina. I know your heart was in the right place. Just know that the faith I have in Robin will not falter. We swore to be two halves of a greater whole. Do not under estimate those ties and the bonds we share. Our bonds have been ever so strong in this timeline, have they not? We can change things, and continue to do so."

The conviction in Chrom's speech was strong and spoken with conviction. Both Robin and Lucina were left speechless as his words rang true in their minds. Lucina, still a bundle of nerves and tangled emotions, turned in Robin's direction.

"Robin, again I apologize for my actions earlier. Please forgive me." Lucina said bowing towards Robin.

As her head came up, their eyes met and Robin blushed a deep shade of crimson. They both stared at each other for what felt like an eternity. Chrom looked at both of them and cleared his throat to break the silence.

"Well, with this behind us now, we should head back to camp for supper. Lissa is on cooking detail tonight, and we don't want to miss that." Chrom said as he walked in the camp's direction.

I had this story in my head for a while now, so it was about time to get it written and uploaded. Combining Robin and Lucina's S support with this scene is an option I wish were available in the actual game. Please let me know what you think and thank you for taking the time to read it.
