I guess that "that night when he started this whole thing" was when hen and him started being intimate or when he decided to be close to hen and help him w/ his health by being intimate (on the first parts of the series) to stabilize the effect of their snakes' pheromones (? I dont remember what its called) on hen's body. Coz everytime ivan and hen gets to sex, hen gets weak coz ivan's "snake thing" is unstable (mentioned by the doctor) that makes hen weak and sickly.
And on the very first part, its explicitly shown that ivan and hen had sex and ivan marked him. Alek just served as a stabilizer lol and he was able to do so coz he's also a snake.
thats what I remember tho. Correct me if Im wrong.
So uhhh the mark is probably from Alec and not from Ivan, because hooooo boi what happened at the storage(ch.80; page 14) and that flashback(ch.79; page 19) from Alec pov where he stated that “THAT night when he started this whole thing... he didn’t expect to turn out like this” something, am I overthinking or what?
