Cover art for Bride lyrics by Mountain Goats, The

A couple of things here. Most importantly, this song takes its inspiration from the film The Bride of Frankenstein (James Whale, 1936, starring Boris Karloff). At the end of the film, the monster's now animated Bride is repulsed by him, when all he wanted was a friend (his only friend, a hermit, he has now lost). He is upset, and shouts to warn Doctor Frankenstein and his wife to leave as he grasps a lever to explode the laboratory. To the Bride and the duplicitous Pretorious (who had the bride created) he blocks their exit and tells them to stay. He shouts to them: "We belong dead!" The laboratory is destroyed, killing them at the monster's pulling of the lever.

The Monster at this point has a limited vocabulary. He has been taught a few words by the hermit in the woods, and only through him does he seem to gain the concept of friendship and love. He is dumb in two senses, of course. He has spent most of his life unable to speak. He is also unable to meaningfully articulate or understand his feelings. The song must be taking a liberty with the fact that if there is a love story here, it is not for the two beings given life in Frankenstein's lab. It does however reflect a lot about the Monster's death at the end -- he makes his gesture count. He is now aware through his Bride of his own creation, but she is not. He can choose their only logical end, regardless of what he feels.
