When Raven is attempting to drown out A.L.I.E., the words she is quoting are a verse of the poem "The Raven" by Edgar Allan Poe. The poem is about a grieving person trying to forget their lost loved one and, in this verse specifically, begging the titular raven whom he believes to be sent as a prophet whether that will ever be possible, to which the bird responds the only word it says: "Nevermore." In the context of Raven trying not to forget Finn completely, and to remember what she's already lost, she could be taking this as a promise.
Murphy says "The things I do to survive." This might be a reference to Game of Thrones (2011) in which a known line from Jaime Lannister is "The things I do for love."
