conversation about planning a birthday party for Johnny, Claudette off-handedly tells Lisa: "I got the results of the test back. I definitely have breast cancer." The issue is casually dismissed and never revisited during the rest of the film. Similarly, the audience never learns the details surrounding Denny's drug-related debt to Chris-R, or what led to their violent confrontation on the roof. Beyond being Johnny's friend, Mark's background receives no exposition; when he is first introduced, he claims to be "very busy" while sitting in a parked car in the middle of the day, with no explanation ever given as to his occupation or what he was doing. In The Disaster Artist, Sestero states that he created a backstory for the character in which Mark was an undercover vice detective, which Sestero felt united several otherwise disparate aspects of Mark's character, including the secretive nature of various aspects of his behavior – including marijuana use – his mood swings, and his handling of the Chris-R incident. Wiseau dismissed adding any reference to Mark's past to the script. The makers of The Room video game would later introduce a similar idea as part of a subplot involving Mark's unexplained backstory, much to Sestero's amusement. At one point, the principal male characters congregate in an alley behind Johnny's apartment to play catch with a football while wearing tuxedos. When Mark arrives, he is revealed to have shaved his beard, and the camera slowly zooms in on his face while dramatic music plays on the soundtrack. Nothing that is said or occurs during the scene has any effect on the plot; the scene ends abruptly when the men decide to return to Johnny's apartment after Peter trips. Similar to most of the other plot points of the film, the event is introduced abruptly and is never referenced elsewhere in the story. Wiseau received enough questions about the scene that he decided to address it in a Q&A segment featured on the DVD release; rather than explaining the scene, though, Wiseau states only that playing football without the proper protective equipment is fun and challenging. Sestero has been questioned about the significance of Mark's shaving, though his only response for several years was "if people only knew." He describes in The Disaster Artist that Wiseau insisted he shave his beard on-set just so that Wiseau would have an excuse for Johnny to call Mark
