Question: do aya and bayek break up?
Answer: The beginning of the end starts with Bayek and Aya standing on a beach with Aya preparing to set sail to Rome to kill Septimius and Caesar, and finally complete her (and Bayek's) cycle of vengeance. On the beach, Aya informs Bayek that they're breaking up. That their love was lost the day their son, Khemu, died.
