Do you think Sergey and Oleg's arc have any parallels?
gonna be honest bestie, i had literally never considered this before today, but now that i have i SO many thoughts.
(sorry, not entirely sure if you mean if sergey and oleg's individual arcs have any parallels to each other or if their shared arc has any parallels so i'm gonna blab about both)
comicverse only, as oleg does not pass the sexy lamp test in the movie.
i don't think there are many parallels between sergey and oleg's individual character arcs (maybe because they're willingly apart for approximately half a second in most of the comics), but the main one that i do think about is that they both go back to their "destruction" for the sake of each other: oleg consistently breaks sergey out of prison (the game, time of the raven), even after he shoots him, and sergey takes on the characteristics of the bird to save oleg from altan.
as for parallels between their shared arc and any other character pairings, i think the biggest one i can pick out is yulia and igor. aside from the fact that oleg is literally meant to be as important to sergey as yulia is to igor during the game, there's also a sort of parallel during time of the raven, with both oleg and yulia being catalysts for their respective partner's kuthk decisions. igor rejects kuthk because he used yulia; sergey accepts kuthk because, with oleg "dead," he has nothing left (yeah ik it's not completely canon but come on).
AND if we take the epilogue into account, you could maybe argue that oleg leaving sergey in the cell parallels igor's vision of yulia, with both being their ways of coming to terms with the game (this one's a bit of a stretch though).
a popular comparison for serovolk is vadim and altan, but honestly it's not really my favourite? surface-level, yeah, they're both rich villain/mercenary combos with things about vengeance, but i personally see them as having very different dynamics. we've only had altan and vadim together for, like, three volumes thought, so maybe this'll change lol.
one more, because i'm on a roll: i think there's a surprising amount of parallels between sergey/oleg and anna/olga from just like a fairytale (major grom). gay criminality aside, both pairs are made up of a rich mastermind hell-bent on revenge and someone willing to do anything to make it happen for them, and both revenge plots are theatrical and personal (sergey fighting igor intellectually, olga taking away her father's wealth). and, in the end, both anna and oleg are fatally shot because of the plots except anna doesn't have the luxury of being besties with local italian politicians
(bonus both get fucked up by igor lmao)
and i know i wasn't going to talk about the movie, but i think it's pretty interesting that both comic!olga and film!sergey get rid of suspicion on themselves by "falling victim" to their own crimes (olga being "kidnapped," sergey getting his shit wrecked by that dude at the casino), even if sergey's not doing it on purpose.
in conclusion: crime is forgivable when it's gayi
