Yes, C.C. does regain her memory.
C.C., a pivotal character, indeed recovers her lost memories during a significant turn of events. This happens after Lelouch's true identity is exposed to the Black Knights. In the ensuing chaos, Rolo is compelled to prioritize Lelouch's escape and secure his safety, which results in C.C. being left behind.
The Restoration of C.C.'s Memories
The process of C.C.'s memory restoration is facilitated by Marianne vi Britannia. While inhabiting the body of Anya Alstreim, Marianne successfully finds C.C. and actively triggers the awakening of her previously dormant memories. This crucial moment allows C.C. to fully retrieve her past, including her true name and the extensive history spanning many centuries of her immortal life. This recovery is a key development for her character, deepening her understanding of her existence and her profound connection to the Geass system.
