What happens in Everhood 2 if you don't interact with anyone?

Thought I'd make this small video because I didn't see anything like this. Other minor changes include the nicknames Irvine and Sam give you, and the pseudo NG+ but i hate that so I'm not including it.

00:00 - early Dragon fight.
07:05 - Phase 3 Dragon
09:39 - reaction to beating the Dragon early
10:44 - Meeting Bobo for the first time in Mushroom forest
11:18 - The speedrun door. (Unrelated but also haven't seen a video of this)
13:24 - Going to the arena after Death mountain without meeting Lucy.
14:10 - Going to Neon district at the end of the game.
