Yami had looked to his friends while Shadow was trying to persuade the young Kaiba in helping them. "That must be it." He looked to back to the duel to see that Mokuba was standing as if frozen, like he didn't know understand what just happened but that this voice was speaking to him. That he shouldnt go through with his plan. To let Yugi help. He felt so confused and scared but that was when Yugi spoke up. His gaze piercing but friendly, kind. "Your big brother is just confused. After I defeated Kaiba in our duel, I opened his mind. I removed from him the Dark influences that clouded his thoughts and actions. Free of that evil essence. Kaiba is struggling. Now your brother realizes that his way isn't the right way, and that he's searching his heart for answers. And you know in your heart what you're doing isn't right either." 

Mokuba looked to Yami, obviously scared but willing to confide in Yugi like the voice wanted his to do. "But then...what can I do?" 

Yami smiled softly seeing that Shadow's help had worked. "You can start by trusting in me, and together we will defeat Pegasus. I promise you, we can only bring Pegasus down if we stick together.  We’ll help you protect your brother, Mokuba, but you’ve got to help us, okay?  You’ve got to go back and return those cards and star chips to the kid you stole them from." 

Mokuba seemed to think this over before giving a nod to Yugi. "You’re right, Yugi. Then we’ll take on Pegasus together!" Mokuba and Yugi then got off the Duel Monsters arena and met back with Yugi's friends. Jaden looked to the two. "We got three minutes left till the boat leaves. We gotta hurry!" 

The group then begin to run in the direction of the docks to give the star chips and deck to the kid whom of which Mokuba had stolen them from.
