Greg grew frustrated, pushing the sandwich away from him onto the floor. He looked at Theo, knowing this was going to upset him, but unable to help himself.
"This food thing is gonna be a huge problem, Theo. I'm thinking crazy thoughts...bad thoughts..," he said, lowering his voice even though it was only the two of them in the room, "I am thinking about using a way to make you eat. Don't you get it?! If I can't see you eating here, make sure you're going to eat when I get you out of here..," and Greg's voice trailed off and he sat back, and rubbed a hand across his head in his distress. Looking up at a high point in the wall, Greg grew grim, "You can't die on me, Theo. I.. I don't know what I'd do if I lost you again, and I..," and now his attention turned to Theo, redirected at his love, "I'd imperio you to make you eat if I had to. I'm not going to lose you again."
Greg's voice was low with a hard edge to it, even as his face was grim, his insides twisted at the notion. He couldn't think of forcing Theo like they did here, tieing him up and force feeding him; better to put him under an Unforgiveable and making Theo feed himself. But Greg wasn't sure what that would do to Theo's mind; it might send him over the edge.
His biggest fear was that Theo would never speak to him again after being invaded by Greg's demands; the option was to let Theo have his way and starve himself to death.
