In Of Mice and Men, what does Lennie's second visitor in Chapter Six tell Lennie that recalls an earlier conversation he had with Crooks?

I think I get the question, but it is awkwardly worded. 
In my opinion, the "second visitor" would be the giant rabbit that emerges in Lennie's
sight as he is hiding from the lynch mob at the hiding place that he and George
established at the start of the narrative.  The rabbit is almost tormenting Lennie about
how Lennie will be beaten and abandoned.  This is reminiscent of how Crooks tormented
Lennie in chapter 4 about George leaving him and Lennie being all alone.  At this
moment, the death of the rabbits and the abandonment issue all come together in Lennie's
vision and it is horrifying for him, as it represents a world spinning out of control. 
It is a moment where much of Lennie's experiences unify together.  It is also
significant because George's arrival results in the rabbit disappearing.  Yet, all of
these thoughts remain in his mind, only to be replaced with one last hopeful vision of
the farm and the dream it represents.  In the end, the second visitor reminds Lennie of
the discussion with Crooks about loneliness and abandonment and the pain experienced
with such emotions.
