Adele’s showed me some sketches this morning, which she said were “yours”
Jane says Mr. Rochester tone seemed to express “What the deuce is it to me whether Miss Eyre be there or not?” That doesn’t seem like something your normal hero would say.
Mr. Rochester tells Jane to stop playing the piano and basically tells her she’s not that good.
Mr. Rochester was shown some paintings/drawings by Adele saying these we’re Jane’s. He doesn’t believe Adele and when confirmed by Jane that they were her originals he still doesn’t believe her. He even goes as far to tell Jane not to lie about them being originals because he can tell.
