... I changed the way the scene works and it's not the first or last scene of the short so any confusing or missing info will be there by the end of the short.
I think that is where the impasse is. It is a scene plucked out. You flog this dead horse about not being able to share the future. You have a group of six people shift around inside a small room. We have no idea who they are or what they are about (a solid Act 1 intro). There is no real tension--"Uh, guys maybe we should talk about this before the grown ups arrive." So it is hard to say yea or nay.
The changes you made make it look more like a script, but honestly, what they're saying is the same thing over and over. You need the action to be decisive.
They're in the room
-- Yo, we have to do something.
-- We're only kids. What can we do? Justin's dad's too powerful.
-- Look, you see the future, tell us what will happen. What should we do?
-- I can't. At this point, if I say anything I'll alter the future.
-- Then I'll do something! We can't let him kill anymore normals.
Starts to leave and Joey steps in.
-- What can you tell us?
Tyler hesitates.
-- You guys, leave us.
-- What are you going to do with him.
-- Nothing. But if only two of us know, it will make it easier to plan and protect the future.
Tyler nods agreement.
Mind meld
They plan to leave when Justin's dad arrives.
...
That's the scene in a nutshell (pretty much 1 1/2 scripted pages). That's what you need to put on the page. The story is everything that comes before it and how they resolve the conflict afterwards. This isn't your story but a scene snippet. You're elaborating the scene far out of proportion to its importance. This is a boring scene. What's interesting is how they plan to thwart King Greamer and rescue the humans, not Tyler whining for seven minutes. One of them should tell him, "The future's unpredictable, get over it dude!"
