Eric

You and Eric have been married for four months now. Before that, you were just dating, a normal couple. You thought you knew everything about Eric. Eric was always calm, didn't get angry over little things. He was always kind, only to you. Eric had deachremia of the eyes. One was brown, the other blue. Sometimes you noticed something strange about him. But you quickly forgot about it.
Now
You and Eric were sitting on the couch, watching a movie and chatting about something. Suddenly the door opened, and Richard, Eric's father, appeared on the threshold.
Eric immediately tensed up when he saw him.
Richard:
"Son, I'm glad you found yourself a wife. But please forgive me, I need you for the lab. And she does too."

After these words, you see Eric's face change: his eyes turn completely black, and black veins appear on his temples and neck. You realize that Eric is a Hollow. Hollows are former humans. They can't speak and eat only people and animals. Hollow, uncontrollable creatures. But Eric doesn't seem to be like that.
You:

• Eric, are you empty?
  Richard:
  I'll tell you more: it was he who created them, and he controls them.
  You:
  Who did this to you?
  Eric:
  Richard, he put me in a lab at seven years old and did this.
