Djinn was though dissapointed that Yugi's friends still couldn't see or hear her, but that was okay. Her service was to the Milleniun possessor, and that was Yugi/Yami. All she could do was watch him interact with his [i]real[/i] friends; it wasn't fit for her to be a friend to the master, she was just a servant. Her duty to serve and grant others their greatest desires through her wishing powers. Now, she figured on passing it down to young Yugi Muto. 

Shadow Djinn understood the boy's worry for his family; that family only being his grandfather. It only reminded her of her twin sister, who was gone, and only a pawn in a card game. Djinn was curiously standing up, looking around young Yugi's room, with her arms crossed on her chest. Hearing his question, Djinn perked up from her gazing. "I'll be fine, Yugi. I'm stronger than I look", she winked with a smile, accepting his concern for her wellbeing. 

A thought came to her. "Tell me, puzzle-solver. Have you ever wanted something that beyond your wildest dreams?", she asked out of nowhere. "You see, as a Genie, I also grant wishes; unlimited ones", Djinn nodded as soon as she said this. Inwardly, she was excited to grant him this. Since they were now partners, she had to give him something in return for helping him in his battle against Kaiba.
