I love the way he shows his excessive concern by repetition.

CH: 28
"How is your niece, Miss Bates? I want to inquire after you all, but particularly your niece. How is Miss Fairfax? I hope she caught no cold last night. How is she to-day? Tell me how Miss Fairfax is."

Seems like a very enthusiastic lover.

" And **Miss Bates was obliged to give a direct answer** before he would hear her in any thing else." :-D

Followed by accepting Miss Bates' invitation to come up.

"Well," said he in a deliberating manner, "for five minutes, perhaps."

"And here is Mrs. Weston and Mr. Frank Churchill too! Quite delightful; so many friends!"

"No, not now, I thank you. I could not stay two minutes. I must get on to Kingston as fast as I can."

His sudden change of decision on hearing who else was there shows some jealousy, perhaps?
