After meeting Skyler, Buffy allows him to depart unharmed rather than slaying him, noting that he seems harmless. This marks the widening of one of the Buffyverse's overall themes, that demons are capable of being benign whereas soulless vampires are not, a concept introduced in Becoming: Part 1 (1998) and explored more fully in Angel (1999).

Eliza Dushku revealed that she and David Boreanaz did Faith and Angel's fight scene themselves: "Day one I did about 2 punches and I've learned as I go on, from the "Enemies" episode with Angel, we did most of our own stunts, me and David have a sick love for fighting. We don't mind coming home with bruises. I love me personally watching the show and my friends knowing it is me. I always want to do my own stunts".
