I think that the line "But I found my mouth stitched shut with glossy pink thread," is a reference to Loki, the trickster god. In Norse mythology, Loki is famous for using persuasion and dishonesty to cause harm. He has mouth sewn shut by a dwarf Brokkr after Loki loses a wager to him, but probably Brokkr has the additional intent of prohibiting him from using lying words towards destructive ends.
