"Spike often nicknames people, both as insults and as terms of endearment; for example, he calls Dawn "Little Bit" or "the Niblet".Spike also retains something of his literary intellect from his human side, routinely referencing poetry, songs, and literature; on occasion he even waxes poetic on the nature of love, life, and unlife as being driven by blood, reasoning that blood is more powerful than any supernatural force because it is what separates the living from the dead.
