For many decades, Tony has unquestioningly accepted his own preferred version of Adrian’s character, one in which Adrian was an intellectual genius far more clever and mature than anyone else, and one whose mental acumen even, perhaps, justified his own suicide. In some ways, Tony’s realization leads him to reevaluate his own past immaturity, particularly regarding the ways he and his friends paid little attention to imagining the pain of Robson’s girlfriend—comparing her to Veronica, Tony now recognizes that there was much more to the story than he accepted. However, it’s striking that Tony is quick to replace the reigning version of Adrian that he’d always accepted with a new, and newly airtight, version—merely creating a new “theory” about Adrian.
