Well it depends on the Squee's mentality and age...
If they're old enough to drive a car around to find him (maybe they just have to have a vague idea and not be legal about it), and crazy enough that first degree murder means nothing (or, like, "avenging Fang's death" or something)...then JP will probably get EndOf's, Tally's, or possibly Ryan's prediction. Wonder who falls into this category...
They're little squealing twelve year olds, then they'll end up having to do Nathan's prediction like "DX WHIIIINNNNEEE~!!".
Now if we get a group of these two together then that'd surely be interesting indeed. A group of rabid twelve years olds and mental people around or over sixteen (or is the driving age eighteen now? I can't remember.). All I can say is it'd be very messy and bloody and horrible.
I wonder if they would have the courage to boycott the following books, or if they would cling onto a tiny amount of hope that he wasn't really dead and keep reading to see if he popped up again?
But yes. Bad things would go down if he killed Fang. I probably wouldnt have kept reading :P
