 The character of Walter goes through much development during the first season. Stuart believed that he changes the most out of the main cast, and his return to St. Claire's reflects this progression. Actor John Noble explained his character's evolution in a November 2008 interview, "We see Walter from a different angle, very vulnerable. He goes back to the asylum again, and we see the very, very fearful man return for a while. Although he does have some wonderful moments earlier in the episode, when he goes back inside he turns into this incredibly fearful, stuttering fellow that we saw when we first met him. It's a very interesting journey we see Walter go through."
