"I do miss Rue," she told InStyle at the time. "She's like my little sister in a lot of ways. And going back to that character is a home base for me." "There is a beautiful second season that has been written, but in order to do it the way we want to do it, we need to wait until it's safer," she continued, noting the challenges of filming amid the pandemic. In order to hold fans over while the cast and crew waited to film season 2, Euphoria released two special standalone episodes over the past year — one in December and the other in January.
