Along with its inevitable corollary, "My brother, Mr. Suckling!" Although not as much fun as Miss Bates's soliloquies, Mrs. Elton's have the advantage of Emma doing a slow burn as she listens, and then giving us her opinion. Here in Chapt. 33, Mrs E. discusses her plans for Jane Fairfax:

"My dear Miss Woodhouse, a vast deal may be done by those who dare to act... [blah blah] We [note how she puts herself on the same level as Emma] have carriages to fetch and convey her home, and we live in a style which could not make the addition of Jane Fairfax, at any time, the least inconvenient... [blah blah] ...Jane Fairfax ...[blah blah] ...Maple Grove... [blah blah]... my brother, Mr. Suckling... Jane Fairfax [blah blah] ...I shall introduce her wherever I can... and shall be constantly on the watch for an eligible situation... [blah blah]...I dare say we shall sometimes find a seat for her in the BAROUCHE-LANDAU in some of our exploring parties."

It seems to me that the above abbreviation is a fairly accurate representation of what Emma actually heard, as shown by her inner commentary afterwards: "'Jane Fairfax and Jane Fairfax.' Heavens! Let me not suppose that she dares go about, Emma Woodhouse-ing me! But upon my honour, there seem no limits to the licentiousness of that woman's tongue!"

But now Emma is off the hook: "Emma had not to listen to such paradings again -- to any so exclusively addressed to herself -- so disgustingly decorated with a 'dear Miss Woodhouse'." Mrs. Elton simultaneously takes herself out of Emma's everyday sphere, and takes any obligation to be sociable to Jane Fairfax off her hands, by monopolizing Jane's society.
