This song plays in-game during scenes of introspection, reflecting upon past mistakes and shortcomings. There are two versions, this one, in 3/4 time, and one only heard in the final season, in 4/4 (which I have yet to complete.)
I struggled with the percussion for this song. I couldn't ever quite get happy with the sounds, and ended up going with the one that sounded best, rather than trying to layer a billion things like I normally do. I didn't think it would fit the song.
