He later appears in "The Penultimate Peril" where he and Charles were at Hotel Denouement and staying in room 674 which was reserved for people in the lumbermill industry. Klaus takes them to the sauna down the hall. Charles explains to Sir that he wants to apologize to the Baudelaires for their treatment. While in the sauna, the two of them talk about a party on Thursday held by a person with the initials J.S. as well as Charles addressing to Sir about fires being used in the lumber industry. Sir planned to do business with some rich people there in order to save his lumber business. In addition, Sir mentions that lumber from Lucky Smells Lumbermill was used to build Hotel Denouement. Frank or Ernest Denouement appears and states to Sir and Charles that the sauna has to be cleared out. To satisfy Sir's claim of liking the burning wood smell, Frank or Ernest has Colette posing as a chemist waiting outside to take them to room 547 where Organic Chemistry is. When Dewey Denouement is accidentally killed during a confrontation with Count Olaf which woke up all the patrons, Sir claimed the Baudelaires caused accidents at the Lucky Smells Lumbermills where Charles stated that Count Olaf was responsible for them. During the blindfolded trial, Sir submitted employment papers as evidence. When Count Olaf starts a fire at the Hotel Denouement, Sir was last seen holding hands with Charles on one of the floors arguing about the use of fires in the lumbermill industry.
