Silent Heaven is hell and heaven combined in one, life and death and your choices to escape the nightmare or succumb to it, thus failing yourself, as the maria ending proves. My canon ending is leave, although the game makes itself pretty clear with the theme of water i still think James survived and chose to honor his wife in some way by killing Maria once and for all. He escaped the town with Laura and started a new quiet life, living as he always wanted to and always remembering the events of the town. Eventually James Sunderland passes away of age and he is reunited with Mary in Silent Heaven, their special place.
I've seen almost every Better Call Saul X Let It Happen Edit on RU-vid but this one managed to convey the bittersweat vibe of the series the most. Great Clip and Voiceover selection, my favorite BCS Edit so far. Thanks for that.
