The lovers, at last alone and freed from the constraints of courtly life, declare their passion for each other. Tristan decries the realm of daylight which is false, unreal, and keeps them apart. It is only in night, he claims, that they can truly be together and only in the long night of death can they be eternally united ("O sink' hernieder, Nacht der Liebe"). During their long tryst, Brangäne calls a warning several times that the night is ending ("Einsam wachend in der Nacht"), but her cries fall upon deaf ears. The day breaks in on the lovers as Melot leads King Marke and his men to find Tristan and Isolde in each other's arms. Marke is heartbroken, not only because of his nephew's betrayal but also because Melot chose to betray his friend Tristan to Marke and because of Isolde's betrayal as well ("Mir – dies? Dies, Tristan – mir?").
