Upon coming back to the warehouse he noticed something odd. "I sense a barrier. Well crafted at that."

The Kaiba got up and cautiously made his way toward a window that showed the front of the warehouse. Sneaking a peak he says Yami and Serena. But whomever he saw made him tense. "Dartz is out there with them! That idiot!" 

Joey perked up at the name. "Dartz?! How?! He should be gone. Passed on and all that!"  

"I know that Wheeler! It's not making sense either." Kaiba answers.
