The CW’s Scarlet Speedster will visit the CBS drama when he finds himself transported to National City from an alternate universe. In exchange for a way back home, he helps Kara fight Silver Banshee (the alter ego of Cat Grant’s assistant, Siobhan Smythe, played by Chasing Life‘s Italia Ricci) and returning baddie Livewire (True Blood’s Brit Morgan).
“It is the most joyous occasion to have these two superheroes together in the same place, at the same time, working together,” star Melissa Benoist told TVLine on Sunday prior to Supergirl’s PaleyFest panel. “They are both so happy with their powers and what they get to do and how they get to help people, that it’s kind of infectious and exciting and upbeat and happy.”
The two crimefighters also enjoy “quite an adorable banter,” sparking some jealousy from Kara’s potential suitor James Olsen, executive producer Ali Adler added.
