This would be when he would end the pain of the animal, but yeah, he didn't do it. Ziio was wise to question how he was reacting. Since there were no other prey, there was no need to be silent anymore.

He knelt down toward the chirping animal.

He only looked up and spoke when addressed.

"Mother," he replied. "This is not an ordinary animal."

Which was an invitation to come see.

There was a small bird. With or without the knowledge on THEIR person, but it was a Rufflet, a Pokemon. A very small Rufflet. It was chirping in pain.

"It is wounded...the wing is broken," he said. "It must have been out here for a few hours, judging from the snow caked on its body."
