Last month, Birds of Prey alum Ashley Scott joined the long list of guest stars who will appear in "Crisis on Infinite Earths," this year's Arrowverse crossover. While details about her role are being kept under wraps, her former co-star Rachel Skarsten -- who currently plays Alice on Batwoman -- dropped a new clue about Scott's involvement.

"I am not allowed to say anything about my involvement in the crossover. However, I can say I'm very excited for Ashley Scott to come back because she played the Huntress in Birds of Prey, which I was in, and we've been chatting, and she's bringing back -- actually, she kept a lot of the costume pieces, and she's going to wear the original costume pieces in the crossover," Skarsten revealed at New York Comic Con.

"I think the crossovers are so lovely because fans of all the shows, you know, get to have their favorites back and, and I too get to have my favorite back in Ashley Scott. So I'm really excited about that," she added.

Notably, Skarsten declined to comment on her involvement in "Crisis on Infinite Earths." Since she also starred in Birds of Prey, there are two possible roles she could play: Black Canary or Alice, aka Beth Kane. Indeed, considering the multiversal nature of the crossover, she could even do both. However, it looks like we won't find out until the crossover airs this December.
