He yells only when he's in a position that most people would be shot in or kicked out of a place for, most people would.

Cheerleader's dad knows because somebody tells him the words "claire cheerleader texas" or he connects the dots in Isaac's paintings.
Again, he knew nothing that would give him any indication that she would die at the homecoming game. The only painting that indicated that she would die precisely at the homecoming game is the one Nathan destroyed, and which only Nathan, Peter, and that, uh, other chick had seen.

It seems the universe is fatalistic because Hiro cannot save charlie. . .she dies anyway, but Peter and the Glasses dude have no problem changing the future when it comes to the cheerleader. You can't have it both ways. The future is either changeable or fatalistic.
