Since in DRS4, Lloyd will be meeting versions of himself from "paths not walked", then how do you imagine DRLegacy!Lloyd would feel about meeting Alter!Lloyd?
Same goes for Lucina assuming she goes with him (from the trailer it looks like he has to do this part "alone", but I can see her loopholing herself into helping)?
(hey Lucina also holds the Green Element, and she's roughly 13-14 when DRS4 happens, so maybe she hears her own call and winds up where Lloyd is by coincidence. bam loophole found adffghhjhgfd)
but noooooooo you're gonna make me wanna write a story where "path not walked" Lloyd is Alter!Lloyd (but only a mirage/vision/what have you) (or he's for the trial Lucina has to go through so then we get Tween!Lloyd too lmao) and Lucina gets her hopes up on getting to be with him again and if Lloyd's going through yet another self-doubt phrase then seeing the ~perfect~ version of himself that his daughter clearly misses certainly wouldn't help matters and Lucina has to deal with letting her bio!dad go again and Lloyd has to contend with the fact that he doesn't have to prove anything to anyone and that he's the best him that could've come out from his circumstances-!
*inhales*
but those are just thoughts
(and ofc father-daughter hi-jinks along the way too)
