Thanks tons for the reply, naw I wasn't confused about route or path, I was more asking if like there was an overall driving plot towards Dave ending up with someone specific (Dean) or if our choice was what the game would end with. In all honesty, I should just keep playing and see for myself lol. So thanks muchly for the answer!
Well no, thats why routes exsist. The reason people push dave towards dean is for their own benefit really.
Examples: tysons confused and planning to leave but wants someone to look out for dave or orlando not being able to be there for dave and wants him to be with someone before he goes.
Other than that the only thing the story pushes is if you're not on deans route you get pushed to clear the air and clearly tell him where you stand.
