We're getting closer. The type here should be QuoteRelation. A quote is too big of an object to point to, plus you get into recursion problems quickly that way. This should be not nested because the potential links can be so large and because Quotes are not an exclusive child to prospects the way, say, comments are to their parents. The name of this should be "quoteRelation" which is the convention we use for non-nested to-many joins of this type.
