Proof!

"Julius says you behave oddly sometimes. Look at him in strange ways while he gets dressed sometimes. What's that supposed to mean? Do you love him? No. It's nothing to be ashamed of. He's a handsome guy. I'm not homosexual." (McAdam 335).

As the novel progresses and the search for Fall continues more people begin to take notice of Noel's increasing obsession with Julius, including Julius himself. At this point in the novel Noel is being interrogated by the leading officer in Fall's case who begins to question him about his relationship with Fall and Julius. Julius tells the officer that he is uncomfortable with how Noel looks at him, and so the officer begins to question Noel what his feelings are for Julius. 

At the beginning of the novel Noel was able to contain his emotions and obsessions in a less obvious way but as the story progresses he becomes more and more aggravated to the point where he cannot control himself. This helps to support my thought that Noel will attempt to get rid of or hurt Julius later in the novel.
