"Why did you say that?" Hara asked Rey.
"I heard him saying strange things about hiding something so he won't be suspected."
Hara looked at Claus, "Is that true?"
"Wait! There's a misunderstanding here! Yes, I indeed said that but I didn't mean anything," Claus argued.
"Then, what are you going to hide?" Rey asked.
"That's my failed prototype. Do you know that vaccine is made from a virus that has been weakened? Those failed prototypes all contained the virus, of course, I wouldn't want the Aeternum to think I'm suspicious because of them, right?" Claus explained.
"That's why I said this is a misunderstanding. It's my fault for muttering strange things, but you shouldn't jump into a conclusion either," he added resentfully.
"I'm sorry, I don't know about your research. I just do what I think is right, sorry for the misunderstanding," Rey apologized.
