Mrs Jennings and Elinor talk at cross-purposes
Mrs Jennings believes Elinor and the Colonel are engaged; Elinor assumes she knows that the Colonel is offering the living at Delaford to Edward. Fortunately, the confusion only lasts this chapter, and doesn't spread to anyone else. Say what you will about Mrs Jennings, but when she's asked not to share news, she keeps it to herself. And both of them are vastly amused at the end of the day when they sort out what was really going on and what the other person was thinking.
Poor Elinor! Elinor and Edward talk at cross-purposes, too
Poor Elinor is trying to figure out how on earth to phrase a letter to Edward when who should appear but the man himself. He was there, dropping off his card as a leave-taking, as Mrs Jennings headed to her carriage, so (operating under the assumption that Elinor wanted him to perform her wedding to the Colonel) Mrs Jennings sent him on up to Elinor. SURPRISE! Let the awkwardness commence!
Edward: Wow. So, uh, this is . . . awkward. But Mrs Jennings sent me up. And I am actually glad to see you prior to my leaving town, since I'm heading to Oxford and we might never see each other again.
Elinor: Well, whenever and wherever you go, you would have taken our good wishes with you. So, uh, Colonel Brandon asked me to offer you the living at Delaford. Unfortunately it's only going to pay about 200 pounds a year.
Edward: Colonel Brandon?
Elinor: Yes. Colonel Brandon. He means it as a way of expressing his sympathy for the fact that your family is a bunch of assholes - a sympathy that Marianne and I share, of course. And besides feeling sorry for you, Colonel Brandon wanted to give you the position to show his approval for your upstanding conduct.
Edward: Colonel Brandon wants to help me. Are you sure?
Elinor: The unkindness of your family makes you shocked to find other people are still nice.
Edward: Not to find that you're kind, even though it's more than I deserve. I'm sure you must have talked Colonel Brandon into this.
Elinor: Dude, you have got this so very wrong, but obviously you are going to misconstrue the relationship between the Colonel and me.
Edward: Regardless of what you say, I am going to misconstrue the relationship between the Colonel and you. Which is why I'm going to tread perilously close to wishing you every happiness in your married life with him.
Elinor: I hope you really like the Colonel, since you'll be living near his house. Where I won't be living, but as we've already agreed, you won't be listening.
Edward: I kinda wish that my future rectory wasn't so close to Delaford, since I assume you'll be living there with the Colonel.
Elinor: *in an aside to the camera* I told you he wouldn't listen.
Elinor: *to Edward* I wish you every happiness.
Edward: FML. But at least I'll have somewhere to live. *mopes off into the sunset*
