Curate, connect, and discover
fyodor probably let sigma see his memories because, by the time he'd wake up after seeing literal centuries of memories, Fyo would have wrecked havoc already (as we can see 🥲). once he'd wake up (god knows when), he probably would , but again dazai and chuuya are in France and the journey would take a heck of a long time. then finally, we know fyodor is gonna escape (probably to avoid dazai even!), so unless they catch the man before they leave, this arc ain't ending anytime soon.
ok wait so if sigma knows everything about fyodor after the exchange, and dazai and chuuya are trying to wake him up, cant he tell them everything? also if dazai kills fyodor, does he permanently kill him because he nullifies fyodors ability? is the only way to kill fyodor to have dazai directly kill him, and can sigma supply dazai with enough knowledge to do so?
