One day in Kingdom Hearts Daycare.....
Sora: *is playing with Riku and Kairi*
Roxas: *is playing with Lea and Xion*
Ventus: *playing with Terra and Aqua*
Young Xehanort: *gets dropped off*
Everyone: *looks at him*
Eraqus, the owner of the daycare: We have a new friend joining us today! This is Xehanort. Say hi, everyone.
Everyone: Hi!
Xehanort:.....
Ventus: Let's go play together! *Grabs Xehanort's hand* *runs off*
Everyone: *resumes what they're doing*
Meanwhile...
Xehanort and Ventus are playing on the monkey bars
Ventus: So how are you? Where are you from?
Xehanort: Oh, I'm from the Land of Departure.
Ventus: Cool! ^_^ You got any hobbies?
Xehanort: Making clones of myself and talking about darkness
Ventus: O.O Mister Eraqus said darkness was bad...
Xehanort: It isn't it's the best thing.
Ventus: O.O *runs off*
Xehanort: *throws a stick at him*
Ventus: *gets hit and falls down* *starts crying*
Eraqus: *hears Ventus and runs out* Ventus! What happened?!
Ventus: *crying* I - I was running a - away from Xehanort cuz - cuz he was talking about - about darkness, and he threw a stick at me!
Eraqus: Xehanort! Apologize to Ventus right now!
Xehanort: *doesn't want to* No!
Eraqus: Xehanort!
Xehanort: Fine...sorry.
And that's why they hate each other.
