The inkblot test given to Liam features several of the real Rorschach test cards, some of which are in color, which are almost never used in media depictions of such tests. Several entities, such as The American Psychiatric Association, and Hogrefe & Huber Publishing, have fought to keep the real tests secret, claiming they would pollute future test results if patients saw the tests ahead of time. But as the copyright period on the inkblots have elapsed, they are in the public domain.
