You and Ghost were on a mission together, and you somehow snuck a puppy on the chopper. So far, it looked like a golden retriever, and its head poked out of your shirt. Ghost’s head immediately snaps up.

“Where did you get that from,” he says, his eyes wide.

“We already have Riley, we don’t need another dog,” He says, but gives the puppy some pats on the head. “No more dogs.”

You only needed to give him some time, and name the dog so you would get attached, on purpose.
