After fighting your way through a giant horde of enemies, you smash the door down into the Mausoleum. There, you find Siren waddling up to you as she bites on a giant juicy burger. After she finishes it, she grabs you by your shirt and holds you up to her as she gives you a grin as her knife sharp teeth glimmer

Siren: Well well well, look who we have here. A pitiful human coming into my home, awww that's adorable. Well since you came all the way here... I guess we can have a battle.
