Call her “Buffy the Bi-Sexual Vampire Slayer.” In the latest issue of the comic-book series, Buffy sleeps with sister slayer Satsu.

Joss Whedon, who created Buffy for the screen in 1992 and TV in 1997, and is the executive producer of the comic which is in “Season Eight,” said the story line “evolved naturally.”

Whedon has written several stories for it, including an opening arc that introduces Satsu, one of nearly 2,000 slayers activated in the television show’s finale. Whedon then developed their liaison over several issues, culminating in the one-night stand in issue No. 12.

This doesn’t mean Buffy is going gay, like old friend Willow. “We’re not going to make her gay, nor are we going to take the next 50 issues explaining that she’s not,” Whedon told The Data Lounge. “She’s young and experimenting, and did I mention open-minded?”
