HBO's first YA drama, Euphoria, has had its third season premiere on Monday, with a new trailer featuring Eric Dane, Jacob Elordi and Sydney Sweeney at the altar. The new season, which follows the transition from high school to the real world, includes more mature material for the cast, including Zendaya's Rue and her former high school peers. The trailer also hints at a new character, played by Darrell Britt-Gibson, playing a bloody electric carving knife over a screaming man. The show's main character, Rue, is seen being interviewed by DEA agents about her involvement in the drug game and potentially in trouble with drug dealers again. The third season of Euphoria is set to begin.
