The fanfiction around Robin finding out they are you-know-what are so freaking good!😁 Thank you so much to the people who worked on this game, and to the fanfic writers who gave me such a delicious amount of angst, while also solidifying Robin as one of my favorite characters ever.
Lucina: In my future, you... You are my father's murderer. Robin: No! That's insane! Why would I kill Chrom? Lucina: I was not certain myself, until now... I knew he had been killed by his closest friend. Having witnessed your bond with him, I doubted it could be so... But today's events make it clear. You are at Validar's mercy. I suspect it's he who forces you to take my father's life, and very soon... Robin: Lucina, wait. Lucina: If my father is right, then we can change our fates. If this dark future is to be averted, sacrifices must be made. I am sorry, Robin! I know this is murder, I... I know that... Robin: Lucina, you don't have to- Lucina: Don't make it harder! Don't resist, and your death will be swift and painless. If you hold any love for Chrom, then let this be done... Robin: ...... Very well. My life is yours... It always has been. Lucina: D-don't look at me like that! I love you! ...Do you have any idea how hard this is for me? Robin: I would give my life for Chrom. ...And for you. Lucina: ...... Robin: Just...promise me you'll find someone else who cares for you. Promise you won't be alone... I want you to be happy, Lucina. That's all I've ever wanted. Lucina: N-no... Ah gods, no... Robin: ...I'm ready now. Do what you must. Lucina: I... I must... Robin: ...... Lucina: Damn me! I can't do it! I love you too much! I'm sorry, Robin. I'm s-so sorry! Please forgive me! Robin: Easy now. Easy. It's all right...
I cryed than I saw it first time (as Lusina's mother). This moment is one of, if not the most, strongest moment in fire emblem. After death of Robin: Lucina: You saved us all, lady. (or something like that) Me: *very angry* (now I understand why Morgan is a better child)
On my playthrough, Robin was Lucina's mother. All that time I was like: LUCINA, LET YOUR LITTLE BROTHER BE BORN AT LEAST, PLEASE. And when the choice came, I thought that Robin would of course give up her life for Chrom and Lucina.
