Alright, here's the first child! I know I didn't do Say'ri, but she was recruited after Lucina, so I'll just throw her in randomly at some point.
"Lucina, do you know why I called you down here?" Robin asked Lucina.
"I'm not sure." She replied.
"Look, Lucina," Robin said. "I'm gonna be frank: I find you attractive. I found you attractive since we first met. And by first met, I mean when you were still going by Marth. That means that, for a good three months or so, I was worried I was gay. Not that there's anything wrong with that! It's just something I know I'm not. Yet, as far as I knew, I was attracted to the Hero-King, Marth! When I was reading history books, I would read about him and go 'Huh. I guess I would do him.' There's still a bit of a awkwardness when I think about it. So I was pretty relieved when you were revealed to be a girl."
"I understand that Robin," Lucina began to say, but was interrupted by Robin again.
"Then I don't see you for a while, and when you come back, it turns out you're the daughter of one of my best friends! That's even weirder! Every time I looked at you, I could see the little baby back at the castle! Needless to say, I had some pretty weird boners."
"...Are you done?" Lucina asked.
"Yes." Robin replied.
"That's...interesting, Robin," Lucina said. "But I already knew that. It's OK for you to be attracted to me. We're married. We've...We've already been through most of this. We have a child together."
"Hi, Father!" A blue-haired Morgan exclaimed, waving at her father from the door. "I want to be a great tactician, just like you!"
"That's great, dear." Robin said to his daughter. "Now go...go talk to your aunt. Or your grandparents!"
"I don't think Chrom is comfortable around me…" Morgan said.
"Well, you just gotta keep trying!" Robin replied. "I heard grandmother is making a pie, and grandfather is there to try it! Go get some! And close the door on your way out!"
"Yes, Father!" Morgan exclaimed, running out of the office.
"...Mother and Father are going to kill you when they find out you gave her permission to call them that." Lucina said.
"They're her grandparents." Robin replied, getting out of his chair to rub her shoulders. "Time-travel put all of us in uncomfortable positions. I've had sex with my best friend's daughter, who's still a baby in this timeline!"
"Stop talking about me in the third dimension." Lucina said.
"I just kinda find all of it funny." Robin replied. He smiled. "Not that I'm complaining." He kissed the back of her head.
Lucina smiled at him. "...I'm not having sex with you in your office."
"Come on!" Robin exclaimed. "Why not?"
"There's a blood stain on your chair and a puddle of urine in the corner there." Lucina replied. "Judging by your stories, there was a corpse on this desk, and, for all we know, someone could be watching."
"I dealt with that!" Robin exclaimed.
"My parents live here." She said. "And there's a giant, gaping hole in your wall."
"I've given up on fixing that." Robin said. "I just figured that, if I was going to tell you that you were fired, you might as well get a nice severance package."
"...Did I seriously travel through time and marry a man who refers to his...privates as a severance package?"
"From what I can tell, you traveled through time to kill Grima, and you ended up marrying him. So good job on that." Robin commented. He felt Lucina tense up, and realized he should backtrack. "Sorry. Sensitive subject. For both of us. I deal with big emotional stuff with bad jokes. "
Lucina sighed. "It's ok. I already know that. Remember when I was going to kill you. If I didn't stab you for killing my father in the future, I would have stabbed you for those jokes."
"Fair enough." Robin replied. "I was kinda asking for it. Like I said, though, you are fired."
"I assumed I was going to be." Lucina replied. "When you told me you were firing everybody, I assumed I was included. Why are you doing it all one-on-one?"
"Tying up loose ends." Robin replied. "It's been...it's been going."
"You got stabbed." Lucina replied. "Should I be here to help you?"
"Nah, I should be good." Robin replied. "It's mainly you guys I gotta deal with. The kids are alright. Unemployed, but alright."
"Well, good luck with that." Lucina said, kissing her husband. "I have to speak with Father. I'll see you at home." She got out of her chair and left the office.
"...I suppose all my meeting can't go like that." Robin said to himself. "Then again, Lucina would probably castrate me if they did…"
So now you know who the wife is! Lucina! I mainly romanced her because I loved the idea of Robin and Chrom having awkward conversations about how he's sleeping with his daughter. Also, MORGAN CAMEO!
I was pretty kind to Robin this chapter. You get a bit of a glimpse into his character, which, if you haven't really picked up on it yet, is pretty different form the character illustrated in the game.
Up next: Owain!
