"In all honesty, we are perfectly fine without your help if it comes to exploiting our discovery. In fact, I'm quite certain we could have it running for years before anyone would get even the slightest hint of it."

Chihiro suddenly stopped his words and just… stood there, leaning over the table while staring straight into Clayton's face, as if making sure to put a great emphasis on the point he was making. 

"Then again, if we do it on our own, once it comes to the light, we won't be able to bear the consequences this discovery will have upon the world," Chihiro stated while spreading his arms out. "That's why, we are here for three reasons," he added while stretching his hand out and showing three of his fingers.
