I think it's interesting to note that in the previous episodes involving the production of Shakespeare's "Macbeth," Father Meehan played the lead role of MacBeth. However, in this episode, Ryan's mother implores Ryan to help her find a lead to replace "Shibetta," who never played the lead in this play. Although it's not made very clear, Peter Schibetta did have the lead role of Macbeth. In one episode we see him come in for an audition. In a deleted scene we see Ryan yell at his mother for giving Schibetta the role of Macbeth.
