Elisabeth Rohm—who left The WB's Angel in 2001 to join the cast of Law and Order—told SCI FI Wire that she would like her character, detective Kate Lockley, to return for an episode of the vampire series. "I would do it in a heartbeat, but I would do it on the side," Rohm said in an interview. "I would come in and have Law and Order work out [my schedule]."

Rohm has met with Angel co-creator David Greenwalt to discuss when her return might fit with her commitment to Law and Order. "I talked to David Greenwalt yesterday," she said. "He's a very good friend, and [Angel star David] Boreanaz is a good friend, so I love the whole family. It's just a matter of timing, and I've been too busy, really. But I'd like to."

Greenwalt executive produced Angel for its first three seasons, after he and co-creator Joss Whedon spun it off UPN's Buffy the Vampire Slayer. As Angel begins its fourth season, Greenwalt is distancing himself from the show, becoming a creative consultant, and will instead focus on producing this fall's upcoming ABC supernatural series Miracles for Touchstone Television.
