Khelfin tried to think fast. A part of him wanted to let Aro take off but a part of him wanted him to stick around. He rolled his eyes and asked Maya: "Shall we go after him?" 

Before Maya could answer, Amy nodded and said "Good idea, let's."

Khelfin stretched out his arm and stopped her. "Not you. Horrible idea. You go work things out with Cooper. Maya and I got this."

His opinion got supported by Cooper, who then took Amy out of there.

Khelfin withdrew Porygon to its pokeball to rest and got ready to follow Aro if Maya was up for it.
