When Aro seemed to take the lead, Khelfin didn't protest much. It was only natural since Aro had the most experience in the fossil hunting. When Team Mewtwo was mentioned in a warning, Khelfin spoke up. 

"Well, I met with some of those Mewtwo Corpers and to be honest, they didn't seem all bad to me. I know Ms Amy puts them up as the villain but I think I know why. Rumor has it that she and Cooper, the leader of Mewtwo Corp, used to be lovers before the Apocalyps. If this is true, she has a personal grudge more than they are actually hostile."

The second he finished his sentence, he realized he revealed quite a lot about his own sympathies and tried to give it a twist. 

"Then again, if Cooper holds the same grudge against Amy, their staff will give us a hard time so we better watch out."

While they were walking, Porygon subtely drew Khelfin's attention, trying to do this without the others noticing. Khelfin knew what it meant. He looked at Aro and Maya and noticed they were talking. Khelfin quickly nodded to Porygon and it rushed over to something in the distance and brought it to Khelfin, seemingly without being seen. [i]An electric memory, this will be perfect for Silvally[/i] Khelfin thought to himself and quickly put it away. 

They both adjusted their walking speed so they caught up with the others. "So Maya, is Zombie your first pokemon ever or do you have experience as a trainer? I used to have more partners than just Porygon but now its my only one left."
