One of the good things that season 7 brought up but they are going to cut off in the finale, it seems (from spoiler pictures): Roger/Killian 2.0 with a modern prosthetic/"robotic" hand, doing things more normally with two hands thanks to high tech. That is unbelievable and ridiculously forced: making him switching back to a medieval (iconic?) hook is one of the dumbest things in the Pantheon of Dumb Things of OUaT. I guess that might be something contractual due to trademark, some kind of legal right obligation for "using" the character “Captain Hook”, I can't see any other reason for such retrograde “replacement”. It's similar to not making Emma using Light Magic for giving Killian 1.0 another hand, or not making "redeemed" Rumple giving back and restoring his original hand - which we know, because we have been told, he had kept in his shop, probably until leaving SB with Belle.
