12. Robin - Benediction
In one of Connor's early appearances as an adult in the Angel episode "Benediction", Angel takes him to a bar where Lilah Morgan has arranged for Justine Cooper - a young woman who became a vampire hunter after her twin sister, Julia Cooper, was killed by them - to be present at the same time as a group of vampires in order for Wesley Wyndham-Pryce to watch her die at their hands. As the vampires attack her, Connor heads to save her, prompting the following piece of dialogue...
Lilah Morgan: "Who's the Boy Wonder? He moves just like..."
Wesley Wyndham-Pryce: "...his father." "The Boy Wonder" is, of course, a reference to Robin, the sidekick of DC Comics' icon Batman.
