Moira Sullivan is portrayed by Lynda Carter, famously known for performing as DC female superhero Wonder Woman in the 1970s television series. This is her first live action appearance in a DC-based television series since then. She later performed as President Olivia Marsdin in three episodes of Supergirl (2015); though not directly related to Smallville (2001) in and of itself, the title character is Clark's cousin Kara.
This episode ends with Erica Durance in a public service announcement for the Christopher and Dana Reeve Foundation.
When they find out about the mystery driver who crashed Lex's car, Chloe asks Clark if they know who Racer X is. Racer X was the mysterious driver in Speed Racer.
Moira's file contained a reference to Project Ares, the details of which are revealed in Prototype.
This is the final episode of the series directed by Terrence O'Hara.
