"I'm not going to talk with you. Not after you confused me with him, Producer."

Well.. Ritsu was mad. What happened? A quite simple thing. You confused him with his older brother, and called Ritsu 'Rei', by plain accident. You produce both of their units, and with their similiarities it's quite easy to mistake one for the other. But Ritsu didn't care.

And now? Now he refuses to speak to you, wrapped in a burrito blanket. No matter how many times you tried to apologize, he just ignored it.

Perhaps you have to try something that'll speak through to him? You don't want him to be mad at you, after all...
