The shots of the crew have them very upset, So this: a. Means it is a beloved crew member giving his life, Or (and more likely) b. a redeemed Harrison, winning the trust and affection of the crew and then being very distraught over his sacrifice. I can absolutely see it. From all his menace, Cumberband Bendersnatch is a beloved actor. Him finding redemtion would make sense and the awudience I think woulld love to cheer for him. That would add to the emotional impact of his sacrifice. Just thinking like a screen writer here.
