If it's just about using healing magic on an Android, that could be possible. But Viktor was deeply afraid of the magic somehow hurting K and didn't want to risk it. With time to heal, he may be able to get past that particular fear. Right now he goes back to that same emotionless expression that he's had for much of this conversation.

"I actually don't need to eat now. Sometimes, I will just to be able to taste something. But I don't have that kind of bodily need anymore."

He also had never been much of a fan of fish.
