Carwin reiterates his innocence in the matter of the murders, although he acknowledges that perhaps his mischief set something in motion that he did not anticipate. As he is concluding his statement, Carwin and Clara hear footsteps on the stairs, and Theodore enters the room. Theodore clasps his hands to his breast and thanks God for leading him to Clara, but he also asks God to confirm again that it is his will that Theodore should kill Clara. He stands a moment, listening. Apparently, he hears no reply because he castigates himself for “eternally questioning the behest of thy maker!” (112)

Clara hopes she can save herself and restore Theodore’s sanity by showing him the devil—Carwin—who deceived him. She tells Wieland that Carwin tricked him with feigned voices pretending to be an angel. Carwin stammers out an incoherent confession. An enraged Theodore orders Carwin to flee, and Carwin does.

When Carwin leaves, Clara sees Theodore’s lips moving. He gazes up to heaven then drops his eyes and looks about as if expecting someone to appear. Each time he does this, he seems to grow more confused.

Clara carries a penknife in her pocket and now takes it out. A moment later, she realizes in horror that she is considering killing her own brother.
