@Kalenabear I'm not sure there's a technical criterion for what a hook has to be. To the best of my knowledge it's a short piece of melody, harmony, timbre, dynamics, or rhythm, or some combination, that stands out from the overall composition and grabs the ear. What Brahms, if I recall correctly, dismissed contemptuously as "effekt"--he was on the anti-Wagner side of German music. And you are right, Eric's Song is rather short on hooks; the melody flows pretty seamlessly; great melody though. If anything, the major hook is what Vienna does vocally at the very end, after the lyrics finish, vocalizing without words. Coming after a long, slow build-up in the song, to me that's an amazing moment of release, sounding as if she simply could no longer find words great enough to express her emotion.
@aaparallel Vienna seemingly never does anything on just one level, and your feeling about black vs. white keys signifying the divide between life and death is quite reasonable, probably true. Not being a pianist I had no idea about the black vs. white keys until Vienna wrote about it, and when she did my mind immediately went to the racial divide in New Orleans that the Katrina disaster made so obvious.
