When Eli turned to him, Nate started to feel uncomfortable. The enclosed environment and the close proximity?..Nate was worried Eli may try to kiss him. Thankfully that never happened and Eli decided just to answer the question. Nate could understand the desire to do what he thought was right and it showed that there was at least some hope for Opie. He couldn't understand what the hick thought was right about slaughtering the LAPD though. Maybe Eli was just insane. 

But as Eli stated, time would answer his question. Nate would just have to keep an eye on Eli until that time came. In the meantime, it seemed Mr Craigh wanted to check in in the woman he brought in and asked Nate where she was. Nate lifted s finger between them and stated "That I can do" He turned back around and pressed the button for the floor the infirmary was on.
