I was looking at some things on the Fire Emblem Wiki, and I noticed that all of the characters have words of encouragement for the Avatar if they chooses to sacrifice themself. I have never seen any character do this. Any idea how you see it?
I'm kinda having trouble understand what your asking but I'll try to answer. When grima takes you away in that weird vortex thing and you lose all hope all the characters you bring into battle give you a kinda of "hey get up don't give up on us now" type dialogue leading to the avatar getting back up, if that's not what you were asking then idk
The thing is, I've done that, but I've never seen anybody say anything. Do you need to be paired up for them to say something, or is my memory just gone?
You might be misremembering. After you choose No, Chrom will go on a speech about how sad it is that you've been sacrificed and whatnot, and everyone chimes in their opinion. That's when the dialogue occurs. Of course, this dialogue will not show up for dead or unrecruited members.
