Tom Lenk

Appeared in Buffy - Im Bann der Dämonen (1997) {Real Me (#5.2)} as one of Harmony Kendall's vampire minions. He later had a recurring role as Andrew Wells in the show's sixth and seventh seasons, and Andrew later appeared in two episodes of Angel: Jäger der Finsternis (1999)'s final season (which, ironically, was the only season in which Harmony actress Mercedes McNab was credited as a series regular).

There's no such thing as a part-time Buffy fan; people watch it compulsively. [at a BtVS convention in Northern Ireland, 30 Sept. 2002]
