One month ago…

Robin laid down on the comfortable, luxurious bed in one of Valm castle's bedrooms. He had a super tiring day before him, and could not remember the last time he laid down on an actual, comfortable bed. After months of living in tents, sleeping on the ground, fighting in battles against Valm in less than optimal conditions such as a volcano, Robin almost forgot the feeling of a real bed for once. For the previous day, Robin had been fighting alongside the Shepherds to seize Valm Castle and defeat Walhart. It had been a super stressful week. Robin had to come up with all the plans of attacking the castle, studying every fort, wall, and enemy positions to ensure victory without loss of life. He had been lacking sleep from the previous week due to overwork. He was just glad all of it paid off, with all the Shepherds living to see another day. He knew that they would have to deal with Validar later, for one moment he just wanted to be stress free and relax.

The Shepherds had just conquered Valm Castle and defeated the conqueror of Valm, Walhart. The entire mood was festive, with many Shepherds now in the massive dining hall enjoying a massive feast and party. Robin was at the feast earlier, seeing Gregor on his Naga-knows-how-many bottle of beer, Stahl devouring anything in his sight, Maribelle chastising others for eating food in a barbaric way and not refined like a cultured person, and other interactions. However, he himself just wanted a place to rest, and asked Chrom to excuse himself to a bedroom in the castle from fatigue.

There was a knock on the door. Robin ignored it at first. It was not that he did not want to go there. He was simply too exhausted and just wanted alone time. However, when the knocking persisted and even became a full force pounding, Robin groggily slumped over to the door, about to get mad at Chrom for disrupting his personal time. However, it was actually Lucina. Robin's anger immediately dissipated and felt his heart beat faster than usual. Even with a scar on her cheek from the earlier battle, Robin practically melted. Ever since the two confessed their love for each other, they have been trying to see each other secretly. It was not easy, with Robin being gone most of the time planning for upcoming battles. They only really saw each other during dinnertime, and even then, all they could do was maybe mutter a few words and exchange a few glances lest it becomes too suspicious.

"Lucina", Robin muttered, "shouldn't you be at the feast?"

"No. I wanted to see you. I missed you so much, Robin."

"But you see me every day! And I am pretty sure you saw me like an hour ago at the victory party."

"I know."- she whispered and move her lips to connect with Robin's.

"Mmmmp."

Although Robin was at first caught off guard, he soon embraced the kiss the two awe-struck lovers were in. They were stuck like this for only around 30 seconds, but to Robin, it seemed like an eternity. Robin could only stare at Lucina in astonishment. He didn't move a muscle. It seemed like he was paralyzed, and Robin looked like he was trying to remember what his name was. Robin blushed, and then invited Lucina to join him in the room.

Present Day…

"...NNGH...AAAAUGHHH..."

"Now, Robin! This is our chance! I'm going to finish it!"

However, Robin had other plans. He knew that if he did not personally defeat Grima, he will eventually just come back and their descendants will have to fight him and potentially lead to the end of the world. Chrom and all of the Shepherds urged him to reconsider, not to sacrifice himself, and tell him there will probably be a better solution in the future. Although nobody in the camp knew of their secret love relationship, Lucina was super insistent, telling Robin that she never had a normal day in life and just wanted to experience a normal life. She promised him that because the war will be over, they can work out all the nuances of the relationship such as getting Chrom to accept the relationship and other details. Robin vaguely promised Lucina he will do all he can to make sure they can live together peacefully after the war ends, but never specified on whether or not he was going to sacrifice himself. In his mind, he already he made his decision. He was going to seal away Grima and hope, through whatever gods or goddesses of luck that exists, that he will survive and make it back. Ignoring Chrom's statement, Robin tranquilly walked forward to face off against his doppelganger.

"... Robin?! Wait, what-"

"...WHAT...WHAT ARE YOU DOING?"

"For once, I'm glad you and I are the same. Now I can give my life to protect those I care for..."

"...YOU WOULD...NOT DARE!"

"I would and I will. The evils you would visit on this world are unthinkable... In some way, I—we share the blame. It's only right we meet our end together!"

"...NOOOOOOO!"

Raising his hand with his tome book, Robin yelled "THORON". A wave of magical electricity came out of Robin's hands, striking Grima. He looked back at Chrom. He was starting to lose his vision and hearing. He could see Lucina in the back, falling to the ground with tears in her eyes, trying to yell something. He could hear nothing. Robin looked at himself to see he himself was dissipating, become a ghost. In a desperate last attempt, he opened his mouth and muttered out:

Thank you, Chrom. For...everything... Tell the others...and your daughter….my last thoughts were of them... May we meet again, in a better life... "

Then everything went black.

Lucina looked on in horror as she saw Robin disappear in the mist. Even though they hid their relationship from the Shepherds for months ever since they met before going to fight Valm, she could not control herself. Tears began to fall uncontrollably from her eyes as she ran to grab Robin, hoping to touch him one last time before he disappeared.

"ROBIN. No. Noooooooo. You can't. You can't just die Robin. You.. You… promised. You promised we were going to live a happy life together after Grima was defeated."

It was no use. Robin simply disappeared like mist into the sky. Lucina watched forlornly as Robin's remains scattered across the air and her hands were touching nothing but the air. It was almost as though he never appeared. Nothing, not even his robe, existed.

To Lucina, the rest of the day was a blur. All the Shepherds were pretty relieved that the war was finally over and that Armageddon was averted. However, nobody felt like celebrating. The death of their tactician, whom personally made sure everybody survived every battle, was heartbreaking for the entire crew. Everybody was making statements about Robin and how they wished for him to come back to him, along with thanking him that he never made sacrifices to anybody in battle to ensure everybody survived. None of this even reached Lucina. Besides losing Robin, there was actually another reason she didn't want Robin to sacrifice himself. Just a few days ago, she realized she was pregnant. After experiencing about stomach cramps and nausea, she secretly stole some of Libra's staffs and using her limited information on staff usage, examined herself and discovered the truth. Worst part was, she was absolutely sure it was Robin was the father. There was nobody else she had been intimate with, and the only explanation was from that night she and Robin spent the night together in Valm Castle after defeating Walhart. It had been one of her happiest days in her life. She knew she should have just stayed in the dining room and not followed Robin when he excused himself to sleep.

Knowing this, Lucina knew that it was not something she could hide from her parents and the rest of the crew months from now. All she could do was mutter, "My father is going to kill me."
