That’s an interesting theory. In my understanding base from the novel. You can imprint base on several reasons..
Imprint at first sight… extremely rare, you guys have to be super compatible. Pheromones cause this mutation (it’s been long)
Long relationship.. this applies to widow alphas and omegas. Which shows after the death.. but this is years of long relationship (so this is a ‘no’)
If you read s1… Kloff is already imprinted before the birth of Rapiel Jr. After Aeroc tried to commit suicide.. when Kloff found him.. his eyes are violet which is indication of the imprint. The fact he keeps finding Aeroc when he tries to commit suicide is his instinct telling him to save his omega… it’s hard to pinpoint when exactly they were imprinted… was it during the five years he was obsessing over Aeroc? Was it during their meeting its weird how obsessed they were of each other…
I think that one is called a bond. a bond is different from an imprint
In omegaverse stories (even hetero ones where werewolves are involved), there is actually a way for the omega to curse their alpha because only the alpha takes the suffering from an imprint which is basically the omega “marking” the alpha and it cannot be broken.
a bond however takes the worse toll on an omega. and yes bond and imprint are different in that sense.
the eyes being purple is an indication of a bond or a rut of an alpha (again, just a common thing I see in some omegaverse stories and kiss me liar and one other bl i forgot the title had them)
it is a bond not an imprint. but yes you could be right in the part where it could be when they spent so much time together, thats possible too
not that nerd for omegaverse but ive been seeing a pattern in the imprint vs bond thing that I think people need to understand because klopp did not imprint on aeroc but aeroc imprinted on klopp?? maybe Im wrong
both need to be in consent in some form to make a bond(but it can be forced by the alpha if they induce the omega)
but usually its the omega that does the imprinting (even in hetero romances where they are wolves and even in the famous Blood Link bl) not the alpha
so in a way aeroc cursed klopp before he died in the 1st timeline
again, this one is on mere speculation
