Why is "there" needed here? I think this it not necessary.

"See where things go from there" is a standard English phrase that means "see what happens after that point". "There" here refers to the point when these characters will "bring a little paint" to the location they are at. Therefore, "there" is necessary here. Ex: Let's drive to the beach and see where things go from there, since we have nothing to do today.
