I see, I think that's a byproduct of "not having control" over the date. The orbs actually will keep spawning of different types, the more of each type you have raises the chance of your character to say something of that same type. For instance: if you have more of the green orbs (Humor) it makes it more likely for your character to say something funny. The outcome of that is still out of your control just like in a real date. Thanks a lot for commenting :)
