Suddenly there was a rustling sound in the forest...

Stormbird Sentry: Well what do we have here?

Onyx was trotting through the forest lost and angry

Onyx: I cant believe I'm adopted and nobody decided to tell me, not even mom and dad tears coming out of his eyes

Stormbird Sentry stunned: This little brat is my brother! Hmmm, maybe I can use this to my advantage.

In the opening of the Everfree forest

Flying: Onyx has gone so far we'll never catch up to him.

Shiny: We'll find him I just know it.

Stardust: Yeah, Shiny is right we'll find him.

Brooklyn: I hope so, it's my fault that he ran out of the castle like that.

Stardust: It's not your fault Brooke.

Brooklyn: I just hope it's not too late

At the Tree of harmony

Onyx: Woah, this must be the tree of harmony...

The tree of harmony suddenly sense Onyx's present and opened a portal as if the tree knew he was coming here for a purpose. Onyx was about to enter the portal until suddenly,

Brooklyn: Onyx, wait!

Tears streaming down his eyes

Onyx: You lied to me and kept this from me my whole life...how can I trust you..

Stardust: Onyx, please wait think about where you're about to enter.

Shiny: Onyx, don't do this.
