The line on p. 27/26 about "'If he invites you up for toast in his study, don't go'", may refer to the incident where Tom is roasted in front of the fire by Flashy and his cronies. The reference to blanket-tossing on p. 45/44, which Arthur puts a stop to, is also an incident in Tom Brown, on Tom's first day. The scene in the dormitory on the first night, when Arthur gets down to say his prayers, also has an equivalent in the book.
