Judging by his reveal in his chat with The A.V. Club, Woodside likes to imagine that his character got as much of a happily-ever-after as a vampire hunter can get with Faith.
He even has a unique claim to fame as a Buffy alum: of all the principals of Sunnydale High School during the run of the of the show, only Robin Wood survived.
D.B. Woodside’s time as Robin Wood was going to end with the series finale of Buffy the Vampire Slayer no matter what, so it’s no wonder that he can laugh about his character’s possible death in the last episode.
