What the actual fuck was that ending. Im so confused can someone explain? Absolutely blindsided me.

Spoilers from here on out





So from what im understanding, isaac was the killer all along? He was the one who killed all those people?? Or he just killed colin and her husband in a manic state because hes a closet yandere (but also because he rightfully hates her husband) and took the blame for all the other murders? I think I can see why he killed colin because maybe he thought that colin was going to “take giselle” away from him by finding the cure to their immortality. And isaac wanted giselle to take the pills because he wanted to live forever with her, so if colin cured them both colin would essentially be “taking away” what he wanted for himself and giselle. Im just so confused as to why he suddenly said he was the murderer all along because I thought we already saw a scene where he and giselle encountered the actual murderer in the forest? Did I make that up or what thats why im so confused rn.

Also what was up with that last scene with the little kid who looks like him and that creeper who im assuming is supposed to be isaac? Why did giselle shoot him? Is the little kid a trap layed by isaac for giselle? So many goddamn questions
