I don't know where you're getting the idea that Zak is the main antagonist (stalker).
ok Main-antagonist may be a bit to much, cause there is Harry... but i think Zak is the "stalker" cause he admitted that hew knew where Emma and Charlotte lived, and even that he was in this house before (in a monologue line) so whats the point in that if he isnt the stalker?
And i think the stalking part is just another part in his plan to make Emma miserable and to get close to Charlotte eventually... and if this is the case, thats really dumb.
But i admit, if iam wrong i will take this back... but than there has to be another "bad person" cause Harry has nothing to do with the stalker, that is for sure.
zack sayd he was in the house before, and how he stated that was more like he is the stalker.
exactly! Everything else dont make any sense... of course he was trespassing in Charlottes house and has to be the "stalker" (or should i say, fake-stalker) just to drive Emma crazy so she will run to him when he will pretend to get rid of the stalker (will probably ask one of his followers to pretend)
What other reason is there to give away that Zak already was in the house?
If there is more to it and another guy is trespassing and turns out to be the "real-stalker" it will be ridiculous and just too much...
Johno was paid by Zak to get the photos (some from Charlotte too of course), Zak placed them and wrote the letters and send the mean messages to Emma. And Zak paid the detective too cause otherwise he wouldnt get away with it, its obvious that the detective in the end of this chapter will do something to David to shut him down. Thats it... if the DEV will come up with another thing about the stalker story it would be really weird and would not make any sense why Zak is acting like he was in the house and even paid the detective (for what? only sending mean messages via handy? Of course not..., the detective should cover up the trespassing and break ins too, and the letters)
For Harry, that will be a whole other thing.
And like this, i repeat myself... this kind of plan and acting doesnt fit at all the dumb and stupid douchebag that Zak is... no way a stupid guy like him can pull off something like that. Mean messages and bullying? Yes. Paying a Detective in advance for breaking in a house with security system just to get pussy? Never ever. Not believable, but the only explanation so far for the things that he has said (or thought) in the game.
