Personal head-canon as a result of this scene: Meg is Eloa.
Eloa, for those not familiar with the tale, is an angel born from Christ’s tear. Lucifer sets out to seduce her and succeeds. She is said to have fallen in love with him, although she does not know he is Lucifer—only that he is a stranger at odds with God. He also falls in love with her, but he’s Lucifer and his version of love is kind of twisted. Long story (poem in this case) short, she tries to reunite him with God, but fails. In the end, her love for Lucifer condemns her to Hell—which actually makes him sad. He tells her his name as she falls.
Seriously. Meg is Eloa in my head-canon and no one’s going to tell me otherwise.
