Sunset would of arrived in the forest via parking her Teeny Ship at the nearest exit spot before getting off the cockpit. She looked around while walking through the woods, holding her Fiery Bravery Keyblade on her left hand.

"Alright... Should be clear enough to focus... I need to avoid telling the others about me literally sending a world into the darkness... Otherwise i may just get a lecture from Twilight..." 

Sunset blurted out while walking, as she sat down on a stump of a tree and began meditation practice as her darkness aura formed as a small purple and black fire. She was trying to change it back to a normal color, but she was having no luck and kept sitting.
Marvin
He would be flying is teeny ship and would land it in the middle of the woods he would step out and would start thinking about what happened to Clayton before still being suspicious of Clayton sudden transformation to a heartless but didn't have a enough evidence to prove his thought he then begins to walk around the forest making sure that there weren't any heartless in the area he would then see Sunset remembering her from before he then began walking towards her and said "Hey Sunset right? Remember me?"
Carl
Sunset opened her eyes before getting up from the seat she had. Soon enough she turned around towards the voice, and had a chill down her spine.

"Y-Yeah... I do... Mehki right? Look, about the outburst from before... That wasn't me... But uh... A different version of me in my head so to speak... Who which guided me to plunge a world into darkness to fill her craving for chaos... Sooo..."

Sunset spoke to Mehki about her situation, and rubbed the back of her head while holding her Keyblade still on her left hand.
Marvin
"Excuse me? You can't be serious right!?" He said with a irritated tone more focused on the plunge the world in darkness part he would then say "Look I know this other version of your guided you to do it but still! You can't just do that!"
Carl
"I... I was..." 

Suddenly her grip on her Keyblade tightened as Sunset's eyes were not visible due to her hair. But then she looked at Mehki oddly with her eyes closed before opening them though her irises were now that of a cat. With a deeper voice, she spoke and said something completely off.

"I was just doing my job hun~! Chaos and darkness are my hunger cravings... But my favorite meal... IS LIGHT ITSELF! And you will NOT stop me while im in this girl's pathetic body!!"

The voice would of aimed her Keyblade while activating Phase Two and fired a Prism Rain at him, trying to hurt him in this now grudge match brawl.
