There's an urban myth that Ben Affleck appears as a diner at around the 26 minute mark but it is not him, the man looks like Ben Affleck but analysis of his forehead and earlobes prove it is not him aside from the unlikely randomness of a Hollywood star appearing as an extra. A second profile glance as Gunn gets up to leave shows the man does not have Affleck's distinctive chin either.
In Guise Will Be Guise (2000), Gunn, having rarely ventured out of the neighborhood he had sworn to protect from vampires, expressed surprise upon learning of Los Angeles' hidden demon community and its haunts, such as Caritas. However, this episode depicts him, in flashback, visiting precisely such an establishment, Jenoff's casino, long before meeting Angel and company.
Angel tells Cordelia that Connor "was going to be a southpaw for sure." He was wrong.
It is confirmed that Cordy and Groo have sex, Cordelia's first half demon lover.
Starting with this episode, Cordelia, who had previously chose to rekindle her romance with Groo over getting together with Angel, shifts her attention from Groo to Angel.
