Premiering May 2, the twentieth episode of Season 3 will feature guest star Anne Dudek as scientist Tracy Brand, who both Team Flash and Killer Frost are after. This isn’t the first time we’ve seen Team Flash square off against Killer Frost, but can the gang rescue Caitlin once again from the icy grip of her alter ego?
