What if Chase didn't teleport?
When he's in the forest, he looks behind him, scared, maybe because he thinks someone's following him, maybe Anti, maybe not.
Let me put this question on the table.
Why did he go to the forest to visit his dead kid(s)?
I think Anti killed his kid(s) at the end of Dark Silence.
Maybe it's a bit crazy, but what if Chase buried them in the forest himself?
He didn't want to go to the police because he thought they were going to accuse him of murder. So he got rid of the bodies...
Anti can get in Chase's mind EASILY (In this case Chase is the one who's making the videos). And it's easier for him when his body, his heart and his mind are weak.
Anti can control Chase and do with him whatever he wants.
Sooo, let say that Chase just... "Sleeps" when Anti possess him.
I could say that the glithes we see during the first Antisepticehe videos are just a representation of Jack and Henrik trying to scape Anti's control because their minds are aware of the danger, but Chase is weaker after Jack's coma blahblah... that's another chapter.
In the next scene, he "teleports", and holds his chest, maybe because Anti gets into his mind through his feelings and heart?
We don't know where that place is for sure, but we know one thing.
There are two people with him, and they would probably freak out if someone just teleported, so maybe he was there before Chase regained control, probably because the trip from the middle of nowhere to the city is long enough to decrease the effects of the alcohol...?
I'm just saying this, Anti wanted Chase to jump.
I'm sorry if I'm killing someone's mood and hype! And for a perhaps bad writing jeje. I really want to believe the teleport thing and see all the egos together in the same place but I just think this theory is a bit more realistic. But HEY IT'S JUST A THEORY.
