What will happen to Littlefoot, given what we know or can suspect now?
Can we assume that he marries Ali?
Will he become enemies with Chomper or has some big choice in the future along the lines of that?
Will he be a good herd leader or a bad one?
Will he stay in the Great Valley or someday get himself banished for going too far in breaking the rules?
Is there anyone, other than Pterano, that he doesn't trust and that isn't an openly declared enemy of his (and isn't Rhett lying to Ali)?
Will he stay friends with the Gang of Five as he gets older or, as happens with some friends as they get older, will they go their separate ways?
Will Grandma and Grandpa longneck live till he reaches adulthood or will they die and will he have to leave the Great Valley and his friends and go live with his father Bron?
Will he suffer future heartbreak or will his mother's death be the last tragedy in his life?
Will he ever beat Cera in a fight or will she always best him?
Does his relationship with Bron ever go south as he gets older and he might wonder why he didn't come back nor did anyone go looking for Bron?
If he does have a family, will he make a good father and husband or, based on his qualities, would he be irresponsible?
