Curate, connect, and discover
Hear me out. What if at some point during the Chain's adventures they come across their past selves WHILE in the middle of their own quests. Like (example) they walk into Wild's era and he's there fighting his first lynel. And now you can either choose the angst or crack path.
Angst: This is Wild like two weeks after waking up in the Shrine of Resurrection. He is fighting this lynel with the same amount of finesse that I did. As in he is losing. Badly. So they either send in one or multiple or maybe they YOLO it and it's the entire gang. They get past Wild back up on his feet, maybe give him a weapon that won't break after like 5 hits, and help him out. Then they go back and present Wild is like 'yeah that happened but I'm better now' or something. Yeah.
Crack: On the other hand, you could also go full speedrunner Wild mode and write him absolutely destroying this lynel. Like this poor thing has no chance against the physics-defying and mindbogglingly unpredictable Wild. This kind of situation is the reason why you can't spell the word "bewildering" without 'Wild' and he fucking owns it. Fuck it, maybe past and present Wild even team up and briefly break the universe via accidental glitch. Yup.
So yeah, this would happen for the entire Chain, ideally. I'll probably write this at some point. Maybe. Who knows. I just thought this up while studying for a math test and it's way too late at night for me to be functioning properly so yeah.
