Summary:

Bood: And what would this person need to get Roz to settle down?
Roz: must be most beautiful person you have ever seen
Roz: very funny but does not know they are funny
Roz: and suck dick like their life depends on it

Or: The Centaurs know that Roz is sad, and probably a little lonely. So they do their best to set him up with someone who matches his specific list of requirements. What they don't know is that their captain has already found that person.
