AU were Emmets selfcare and self preservation subconiously takes form of Ingo to stop him from doing unhealthy things or destroying his own body.
Has the negative side effect of Emmet keep doing things because he is "with Ingo in a way".
Honestly sounds interesting and could also lead into a Emmet gets therapy situation.
(On the other hand the image of Ingo having this unknown man in white encouraging to keep going and avoid danger even if his amnesia sometimes frustrates him would also serve as a nice parallel. He doesn't know who he is but everytime he gets told to keep on going he can't help but do what he says)
subconcious Guardian Angel?
Hmm! That’s pretty much what this smoking series is sorta doing? These visages of Ingo are just his own subconscious (and old memories of his brother) trying to get him to not fall into old habits sksksk Emmet cares and depends on routines in his life, so having “Ingo” there, even if its not really him, aids as a reminder to not derail too much -> coping mechanism
As for Ingo’s case, this “man in white” that keeps appearing in front of him mostly appears only when he’s in danger, as a sort of “third man factor” phenomenon, to help guide him/encourage him to safety, which is something that has happened to actual people and something super interesting to read about!
“Subconscious guardian angel” au is an extrEMELY cool au name tho and I might have to snatch it whenever I draw something similar to these comics sksksks
