To expand in the Came Back Right thing;
All his prison tattoos, gone. All his scars, gone. The various enhancements he developed to survive over the years (claws, sharp teeth, heightened senses and healing), gone. Disabilities both mental and physical, gone. He has all the memories and knows the associated emotions, but he doesn’t feel them anymore. Not sure if he still loves Britain, Jakob, etc. He doesn’t have all his survival instincts and strength anymore. He’s no longer an anti-authoritarian revolutionary/ contrarian. Every cornerstone of his identity is just. Gone.
