This is sublimely ridiculous, from Rilian's pronoun confusion to Trumpkin's (occasionally deliberate?) inability to hear the nuances of what Rilian is trying to say, to Jill's adoption of Trumpkin's "this and that!" exclamation pattern, to Eustace's plan to lock them in a room if they hadn't sorted themselves out by the time he got home. I love seeing Jill and Eustace staying and growing up in Narnia -- it always seemed a shame they were denied that experience -- and I am glad Jill and Rilian get a chance at happiness together. :-)
