Credited as separated roles, Rocha has discussed about her Buffyverse characters, Halfrek and Cecily, being the same entity: “My personal feeling is that they probably are the same person. A lot of people come up to me and they all want to know if Cecily and Halfrek are the same person. So, I always ask what they think, because I’m interested in different perceptions of that. There’s some thought that maybe Cecily went to the party to reject or seek vengeance on someone else, and that Spike somehow got in there, or that I just wanted to spurn him and hurt his feelings, which I did, which made him become a vampire, basically.”
