I know that a lot of people are either saying that they are hoping that the children or any other character makes a return but I just can't get the idea of them returning out of my head, which is most likely because I loved their development (Mostly) and how truly awesome they are. You see, I can't get all these ideas of how they return out of my head, so I decided to just ask if they are plausible and to actually stop myself from continuing to fixate on the ideas.
The first thought I had was that they return as reincarnations, and I know that Rhajat, Asugi and Caelodori were rather cringe-worthy but hear me out, as this idea would allow them to return without story inconvenience as it could easily keep to a vague fates story choice as it could e that as hey are returning home they are ambushed and killed by assassins, and when the odin reincarnation supports with selena's it can go that he keeps having nightmares of being ambushed by scary men and he remembers a red haired girl with him and her getting shot by an arrow and feeling despair and then it goes black. Then I realised that may not be very realistic as in Birthright Laslow dies so it could never be that he was with them. So if they did do a support similar to that it could never be with the laslow reincarnation, unless only it their deaths were from odins view, which in that case if laslow dies after odin it would mean he did not see his death, or of course odin reincarnination in the support says he remembers seeing an arrow going towards someone and jumping in their way. I also like his idea for the reason that they could make a shy laslow who was not told to flirt to get rid of his shyness plus who doesn't want more manhandling moments.
Another thought I had was that after they were returning to ylisse, another being transported the three of them to a another new place, but the person says that it was a mistake that the trio was brought here it was supposed to be the children (Purposely Vague) and they being their noble selves take the childrens place thus entering in their 4th war.
Also could you tell me if it is plausible or just a horrible idea and you don't want to see any more characters returning and I am being stupid
