Vincent meets with Catherine at the Stray Sheep, as promised by Boss. During the meeting, Vincent confesses his love to Catherine, explaining that he is now "free" from the "herd" of society, and makes his proposal to marry her. Catherine is confused by the proposal, but admits that she has felt similarly. However, her answer is cut short by the appearance of Nergal: Catherine's father and lord of the Underworld.
Several weeks later, Catherine and Vincent are waking up in Vincent's room after a wild night. Vincent notices that Boss is lying in his bed, wearing sheep pajamas. Catherine explains that he is there to watch over the two. Catherine hugs Vincent, saying, "It's better when someone's watching...", and she pulls herself on top of him. The camera pans out and, through Vincent's bedroom window, the Underworld and Astaroth's tower can be seen, implying that he and Catherine now live in the Underworld.
